Hair health is a priority for many people, seeing that it plays a vital role in their identity. That said, there are many reasons why one might be suffering from hair loss and other related symptoms. There is the unavoidable factor of hereditary hair loss, for starters, which is a natural combination of genetics, hormone levels, and aging. Then there are others including, but not limited to, childbirth, hairstyling products, stressors, crash diets, and alcohol consumption. As hard to swallow that hair loss will take form at some stage in life so that hair supplements can prevent premature conditions. 

Over 50 million men and 30 million women suffer from some form of hair loss in the United States. The older you get, the more likely you are to experience thinning, with a whopping 66% of men experiencing hair loss by 35. Whether it's male pattern baldness, more fancily known as "Androgenetic Alopecia", is ingrained in your family history and genetics, but there are ways that we can reduce hair loss in men and promote hair regrowth too. 

Hair supplements are often sought as means of fulfilling hair-related nutrient deficiencies. In turn, this may help to improve hair quality and, to a certain level, strength and appearance. Fortunately, several vitamins, minerals, plants, and herbs have been proven to help target the root cause for poor hair health. In other words, individuals are looking at solutions that work on the surface and from the same follicles through which hair grows. What might these supplements be? Our editorial team managed to muster brands that met our carefully listed ranking criteria, popular demand, or a combination of the two. Captivated to see how one compares to the other? Well, let’s get started:

Hår Vokse  

  • Company: Wolfson Brands  

  • Starting Price: $59.95  

Hår Vokse is said to be the world’s first premium and natural hair rejuvenating system with a patented Marine Protein Complex™. It also contains a wealth of key vitamins, minerals, and antioxidants intended to stimulate natural healthy hair growth. Simpy put, it’s a lasting, effective hair re-growth solution that works from the inside out.   

Not only does it help to make your hair healthier overall, but it also works to stimulate new hair growth as a result of its unique formula and natural ingredients.    

Discovered and developed by Norwegian researchers, Hår Vokse is actually a breakthrough technology in hair restoration therapy. It was discovered while researchers were investigating the effects of fish protein on hair loss.   

Hår Vokse has been shown to be effective in clinical studies, with 63.9% of test participants reporting vital and significant hair re-growth. The formula works by promoting a thicker, fuller head of hair. It accomplishes this by using natural ingredients to strengthen hair follicles and slow hair thinning.   

The ingredients used in the clinically proven formulation include: Vitamin E, Vitamin B6, Selenium, L-Arginine, Copper, L-Cysteine, Biotin, Hydrolysed Marine Collagen, Rosemary Leaf Extract, and Amla Extract.   

These ingredients work together to create a two-step system that works first to promote healthy hair growth by fortifying and protecting the hair follicles. Then, it nourishes and conditions the hair as it grows—resulting in more hair that’s stronger, tougher, and healthier. It also comes with a 60-day money back worry-free guarantee. Try it risk free here!  

Divine Locks  

  • Company: Inner Beauty & You 

  • Starting Price: $39 

Divine Locks is a hair supplement that has been formulated to increase dermal papillae cells production. Hair dermal papillae cells are specialized mesenchymal cells located in the dermal papilla, where the latter is found at the bottom of hair follicles. These cells are necessary for hair formation, growth, and cycling [1]. Additionally, existing dermal papillae cells are likely to become stronger. Since they work similarly to a straw, essential nutrients delivery will be halted when pinched, giving rise to undesirable conditions such as brittle, wispy, and weak hair strands. 

The ingredients responsible for the perks above have been compressed into a proprietary blend of 1210mg. In it, individuals will find the likes of Methylsulfonylmethane, Hydrolyzed Collagen, L-Methionine, Gotu Kola, Citrus Bioflavonoid, Grape Seed Extract, Hydrolyzed Keratin, Alpha Lipoic Acid, Fo-Ti Root, Amla Fruit, Goji Berry, Silica, Hyaluronic Acid, Bladderwrack, Nori Yaki, Wakame, Olive Water, Astaxanthin, and Di-Calcium Phosphate. In addition, each serving delivers Vitamin C (400mg), Vitamin E (40mg), Biotin (50mg), Vitamin B5 (20mg), Calcium (85mg), Zinc (20mg) and Selenium (140mcg). Simply put, the Divine Locks complex for healthy hair growth vitamin support is a great measuring stick as we go through the best hair growth products in 2021 due to its unique blend of ingredients of highly potent dosages and extracts that all pack a punch together when it comes to fighting hair loss naturally.  

Hair Revital X  

  • Company: Zenith Labs 

  • Starting Price: $59 

Zenith Labs had to make the cut simply because of their strategy. Instead of listing over 25 ingredients per serving, they stuck by 12 believed to stimulate hair growth cycles for both men and women. Deemed a scientifically backed formula, Hair Revital X has the potential to balance DHT levels in the body (i.e., the number one hair loss hormone), stimulate regrowth of thinning and receding hair, and fortify hair follicles and hair cells. What makes their solution interesting is that they’ve considered the most common scenarios for hair loss, i.e., family history, poor follicles health, melanin production, and scalp health. 

Taking everything into account, the ingredients responsible for such healing and maintenance are Vitamin A (3350IU), Folate (667mcg), Biotin (2000mcg), Pantothenic Acid (20mg), Zinc (10mg), Pyridoxal-5-Phosphate (20mg), Saw Palmetto (500mg), Stinging Nettle Root Extract (200mg), Soy Phytosterols (120mg), L-Cysteine (100mg), L-Methionine (100mg), and Pygeum (30mg). Zenith Labs rarely carries a proprietary blend aside from a relatively more uncomplicated formula compared to the other picks in our list. At large, this is beneficial, as it informs everyone of the concentration per ingredient. Because of the high-profile nature the company in Zenith Labs carries given its leadership position in the supplement industry, the flagship hair growth vitamin supplement for men and women is a high-quality formulation that adheres to strict purity, potency and quality standards. It is not hard to recommend a very trusted and reputable brand given the Hair Revital X pills and topical solution for advanced hair regrowth results.  

Hair Hero  

  • Company: Essential Elements 

  • Starting Price: $29.99 

Hair Hero is advertised as a powerful hair growth formula that supports hair health and skin and nails health. According to the Essential Elements team, the whole-body nutritional approach is the best strategy to take, seeing that it is likely to have lasting effects for healthy and full hair. And so, this is what the Hair Hero formula allegedly embodies. With time, individuals will realize hair growth, protection against hair loss, and utmost strength. Regarding ingesting this supplement, some complaints have been made about its strong smell and taste, which is something to consider before placing an order. 

Finally, we have the ingredient list, which is similar to the route taken by Inner Beauty & You by the looks of it. Specifically, each serving delivers a proprietary blend of 1275mg constituting Methylsulfonylmethane, Hydrolyzed Collagen, Organic Kelp Extract, Saw Palmetto, Horsetail Grass, Bamboo Stem & Leaf, Flaxseed Oil Extract, and Borage Oil Extract. Others include Vitamin A (900mcg), Vitamin E (13.4mg), Vitamin K (100mcg), Thiamin (10mg), Riboflavin (10mg), Niacin (5mg), Pantothenic Acid (40mg), Pyridoxine (10mg), Biotin (50mg), Folic Acid (416mcg), Iron (10mg), and Zinc (10mg). 


  • Company: Vita Balance Inc. 

  • Starting Price: $24.95 

Foligray has been formulated with graying hair in mind. As per the Vita Balance team, the latter can be prolonged by making simple tweaks within the body’s processes. Notably, the selected ingredients are believed to nourish hair health and pigmentation. Speaking of hair pigmentation, our hair gets its color from a group of molecules called melanin. Melanin can be further broken down into two types: eumelanin (darker shades) and pheomelanin (lighter shades), where the ratio of the two decides hair color. Unfortunately, with age and oxidative stress, cells called melanocytes process less pigmentation known to dye the hair as it is grown from the follicle, hence, the graying effect. The evident discrepancy in melanocytes’ function is the main issue that Foligray is said to tend to. 

To reverse graying, the team trust that the combination of Catalase (5000IU), Horsetail Stem (100mg), Saw Palmetto Berries (300mg), Para-Aminobenzoic Acid (200mg), L-Tyrosine (200mg), Plant Sterols (100mg), Nettle Root (100mg), Chlorophyll (20mg), Fo-Ti (20mg), Barley Grass (20mg), Vitamin B6 (10mg), Folate (670mcg), Biotin (300mcg), Pantothenic Acid (300mg), Zinc (10mg), and Copper (1mg) will strength our hair pigmentation system altogether. 


  • Company: 

  • Starting Price: $69 

Folital is advertised as the only 100% natural blend that targets a highly poisoning toxin called Thallium, responsible for hair loss and ensures that our hair follicles produce healthy hair. The unnamed team behind this solution makes the case that the toxin makes itself a home within the dermal layer of the skin, where our hair follicles are situated. Their existence prevents hair from receiving vital nutrients, leading to poor hair health. 

To reverse the issue at hand, Folital was created, which is trusted to work in five steps. In particular, each serving is believed to eliminate toxins from the blood, purify the bloodstream, deliver nutrients that revamp hair follicles, condition the scalp, and induce wellness all around. As for the ingredients, 29 of them have been included, i.e., Vitamin B1, Vitamin B2, Vitamin B6, Psyllium Husk, Bentonite Clay, and Flaxseed. In general, Folital appears to have garnered a lot of attention lately, and so, it was included solely based on popularity. But our analysis suggests that it lacks both substance and transparency, making it a very doubtful solution. 


  • Company: Vita Balance Inc. 

  • Starting Price: $24.95 

Folexin is a professional formula that promotes visibly radiant, strong, thick, and beautiful hair while strengthening our hair’s natural growth process. To achieve the latter, the team at Vita Balance Inc. carefully measured a series of vitamins, minerals, and botanicals for utmost nourishment. Speaking of the hair cycle, this supplement is formulated to tend to not one but all three stages of hair: anagen, catagen, and telogen. The end goal is to get to the telogen stage with maximum strength, seeing that this is when hair is released from the original follicle and eventually falls out. 

In keeping up with everything that has been discussed up to this point, the Folexin formula encompasses a proprietary blend of 409mg and a separate vitamins and minerals blend. The same components found within the two include PABA, L-Tyrosine, Horsetail Extract, Fo-Ti, Bamboo Extract, Nettle Root, Peony, Spirulina, Saw Palmetto, Plant Sterols, Alfalfa, Barley Grass, Vitamin A (120mcg), Vitamin C (120mg), Calcium (80mg), Iron (14.5mg), Vitamin D3 (20mcg), Vitamin E (14mg), Vitamin B1 (6mg), Vitamin B6 (8mg), Folate (1467mcg), and Vitamin B12 (12mcg). 

Hair La Vie  

  • Company: Hair La Vie 

  • Price Range: $9.99 to $89.99 

Hair La Vie is a company on a mission to help boost consumer confidence through natural means of enhancing hair health. In 2014, a group of health and wellness entrepreneurs responsible for nutritional products got together to help women overcome hair concerns. After hearing cancer survivor and team member at Hair La Vie, Carla Rivas’ hair journey, clinically proven ingredients were handpicked to prevent women from going through such struggles. Here are a couple of words directly from Hair La Vie: 

“While women may start their Hair La Vie journeys for many different reasons, the positive benefits that result are universal, as feeling good about your hair is directly linked to having more confidence. This is a gift that we believe all women deserve, and one that can unlock endless growth and potential.” 

Seeing how far the company has come, i.e., their processes, level of transparency, and unique solutions, a good portion of our top 2021 solutions have been formulated by Hair La Vie. Each of their solutions targets different hair-related issues, but with one thing in common: nutrients deficiency. In the next couple of minutes, individuals will be introduced to three unique takes on hair repair, rejuvenation, and reparation, respectively. 

Revitalizing Blend Hair Vitamins  

  • Company: Hair La Vie 

  • Starting Price: $39.99 

Revitalizing Blend Hair Vitamins is believed to promote immunity and healthy hair growth from within damaged hair follicles. Hair La Vie and Essential Elements have one thing in common: they both highlight the significance of whole-body wellness, i.e., that is, to work from the inside and out. As for how it’s meant to work, each serving will start by conditioning the scalp. By the second month, roots and follicles are likely to become rejuvenated. A month later, visible improvements to hair health can be anticipated. It is by the fourth month that results are trusted to be ever so stunning. 

Results within four months might sound too good to be true, but as per Hair La Vie, it can become a reality because of the selected ingredients. What might they be? The supplement’s fact suggests a proprietary blend of Methylsulfonylmethane, Hydrolyzed Collagen, Organic Kelp Extract, Saw Palmetto, Bamboo Stem & Leaf Extract, Horsetail Grass, Flaxseed Oil, and Borage Oil (1260mg). Supporting ingredients include Vitamin A (900mcg), Vitamin E (13.4mg), Vitamin K (100mcg), Thiamin (10mg), Riboflavin (10mg), Niacin (5mg), Vitamin B6 (10mg), Folate (400mcg), Biotin (5000mcg) and Pantothenic Acid (40mg). 

Clinical Formula Hair Vitamins  

  • Company: Hair La Vie 

  • Starting Price: $49.99 

Clinical Formula Hair Vitamins might help with hair maintenance, primarily in terms of volume, density, and shine. With reparation, rejuvenation, and care in mind, this formula is expected to deliver a good source of nutrients that, by the third month, might reveal an average hair growth rate of one to two inches every three months. Like their previous solution, four months is all that’s required to see a significant improvement. 

Starting with the proprietary blend of 500mg, Clinical Formula Hair Vitamins relies heavily on Reishi Mushroom, Amla, Flaxseed Powder, Bamboo Stem & Leaf, and Horsetail. A vitamins and minerals blend has also been considered, through which individuals will receive a decent concentration of Saw Palmetto (320mg), EVNol Max® (100mg), Hydrolyzed Collagen (350mg), Beta Carotene (1800mcg), Vitamin D3 (20mcg), Vitamin E (3.5mg), Niacin (18mg), Pantothenic Acid (14mg), Pyridoxine (2mg), Biotin (5000mcg), Folic Acid (200mcg), Iodine (200mcg), Selenium (200mcg), Zinc (15mg), Iron (18mg), and Copper (1.65mg). 

Renewing Growth Treatment  

  • Company: Hair La Vie 

  • Starting Price: $34.99 

The official website describes Renewing Growth as delivering concentrated, multi-level support for stronger, denser-looking hair. As a result, individuals can anticipate improved growth and reduced oiliness within a month. This solution is desirable because it increases volume, promotes hydration, and makes hair resistant to tangles. These outcomes are realistically possible after the 3-month mark. Among the several ingredients found in this formula, the active ones with maximum potential include Ecklonia Cava, Capauxein™G2, Capixyl™, fiberHance™ BM, Procataline™ Biofunctional, and AquaCat™. 


  • Company: Hers 

  • Price Range: $15 to $159 

As a team of women who value their health, the creators of Hers decided to roll up their sleeves to get it done for women facing similar health concerns. Based on our analysis, this company specializes in matters involving women’s health. How did they prioritize which issues to emphasize? Simply put, a solution has been formulated for every possible skin, hair, mental health, and sex drive-related issue women are likely to bring up with their health practitioners. 

Speaking of hair health, women can turn to Hers for any issue ranging from healthy hair growth and repair to hair strength. A facet unique to this brand is the medical advisory board of women who oversee all the products before making them available to the general public. Another one worth mentioning is the customized hair quiz, which helps women narrow down their respective conditions. Consequently, the products that carry the most potential benefits on an individualistic basis. 


  • Company: Hims 

  • Price Range: $15 to $159 

The same team who brought Hers to life is responsible for Hims. Society tends to link it to women when we think of hair health, but men need the most support. Why should they settle for anything less of perfection right? This question led to the creation of a brand that is more accessible and carries affordable prescriptions, products, and medical advice for men. Like Hers, all the listed products include scientifically proven ingredients to promote results. To get started, individuals might want to give the quiz on their official website a try to see what issue needs prioritizing. Unlike the Hers collection, those for Hims are smaller, but our editorial team sees this as a significant first step towards inclusivity. 

Amplifying Glaze


  • Company: Kintsugi 

  • Starting Price: $68 

Amplifying Glaze is a volumizing treatment serum that combines the effects of marine extracts, premium polymers, and restorative protein compounds on hair. Consequently, individuals can anticipate a lightweight, flexible hold that boosts every strand of hair into a fuller, denser, and voluminous one. Other suggested perks of using the Amplifying Glaze include increased moisture, strengthened hair, and protection against dullness and breakage. Key ingredients responsible for such improvements include SymHair Force 1631, Procapil, and Kerastore 2.0. 


  • Company: Kintsugi 

  • Starting Price: $78 

Brought to us by the same creator of Amplifying Glaze, KeraNew is a formula that specifically targets aging hair. The whole-body nutritional approach appears to have been considered here, as the Kintsugi team insists on feeding strands of hair from the inside out. What exactly will our hair receive through this formula? Protein and natural extracts have been infused in a unique blend for fuller, healthier, and more youthful hair. To be more precise, each capsule is said to contain Keraplast DFK GLOW™ (500mg), Hydrolyzed Collagen I,III (100mg), MSM (50mg), Acerola (25mg), Hyaluronic Acid (25mg), Bamboo (25mg), Ginkgo Biloba (25mg), Panax Ginseng (25mg), Saw Palmetto (25mg), Burdock (25mg), Moringa (25mg), Hibiscus (25mg), Aloe Vera (25mg), Ashwagandha (25mg), Nettle (25mg), Horsetail (3mg), Vitamin D3 (125mcg), Vitamin E (15mg), Niacin (25mg), Vitamin B6 (5mg), Biotin (2500mcg), Pantothenic Acid (15mg), Iron (18mg), and Zinc (30mg). 


  • Company: Nutrafol 

  • Price Range: $79 to $89 

Nutrafol is yet another company whose extensive process impressed our editorial team. They couldn’t pick just one product. As a team, the goal is to be a brand that offers well beyond untested alternatives to hair drugs; they spent time and effort into finding means that can help them stand out. What might be the result be? Well, let’s just say that Nutrafol embodies the coming together of scientists and doctors who stress the importance of science in every solution offered. To add to those above, some form of tradition has been instilled using natural ingredients, but at large, only those that synchronize tradition and science are believed to have made the cut. 

Another facet that we admired about this brand is that it didn’t initially help the public. Instead, it stemmed from resolving the founder’s, CIO’s, and medical advisor’s hair issues. How can you go about helping others when you have some healing of your own to do, right? This is yet another piece to Nutrafol, among several others that makes this brand exceptional. Of course, the added benefits of having access to their clinical trials enhance trust in the brand. Honestly, we can keep going about the brand, but let’s jump right into their primary products to keep things to the point. 


  • Company: Nutrafol 

  • Starting Price: $79 to $89 

Nutrafol’s Women has been formulated to improve hair growth with visible thickness and strength in mind. The team claims to have reflected upon specific causes to achieve optimal hair health, including stress, environmental impacts, hormonal imbalances, poor metabolic function, and nutrition deficiency. The doctors and scientists created a formula that can unveil its full effects by the sixth month. The first three months alone marks strengthened, shiny hair with a significantly reduced rate of shedding and breakage. 

As stated on the official website, 21 ingredients have been included, which include a Nutrafol Blend of L-Cysteine, L-Lysine, L-Methionine, Solubilized Keratin, Horsetail, Japanese Knotweed, Black Pepper, and Capsicum Extract (530mg), the Synergen Complex® composed of Hydrolyzed Marine Collagen Type I & III, Sensoril® Ashwagandha, Saw Palmetto, Curcumin, Palm Extract and Hyaluronic Acid (1680mg) and a vitamins and minerals blend of Vitamin A (5000IU), Vitamin C (100mg), Vitamin D (2500IU), Biotin (3000mcg), Iodine (225mcg), Zinc (25mg), and Selenium (200mcg). In the meantime, their 3-minute Hair Wellness Quiz is highly recommended to see what leading factor is causing one’s hair-related concerns. 



  • Company: Nutrafol 

  • Starting Price: $79 to $89 

Like Women, Men targets hair growth and scalp coverage. The approach is practically identical, where the leading causes under consideration include stress, environmental impacts, hormonal imbalances, poor metabolic function, and nutrition deficiency. The difference between Women and Men is the concentration of ingredients. Specifically, the Nutrafol and Synergen Complex blends are slightly higher in concentration for men than women (i.e., 575mg and 1720mg, respectively). Additionally, some of the listed vitamins and minerals are likely to vary as well. As for results, the suggested timeframe is the same. On that note, we encourage all men to give the 3-minute Hair Wellness Quiz a try to see where they stand health-wise. 

Procerin For Men 


  • Company: SpeedWinds Nutrition Inc. 

  • Starting Price: $49.99 

Procerin For Men is a dietary supplement designed to help with male pattern baldness and other related hair concerns. This solution contains clinically proven DHT blockers and nutrients essential for hair growth, healthy scalp, and strengthened hair follicles to witness new growth in the crown and temple areas. Each purchase might include Procerin Scalp Therapy Foam, which targets the scalp as suggested in its name. As for the alleged blockers and nutrients, they are found in the form of Vitamin B6 (5mg), Calcium (200mg), Magnesium (150mg), Zinc (15mg), Saw Palmetto (600mg), a proprietary herbal blend of Eleuthero Root, Gotu Kola, Muira Puama Root, Nettles, Pumpkin Seed and Uva Ursi (30mg). 


  • Company: N/A 

  • Starting Price: $59.95 

Profollica is a hair recovery system created with men in mind. Just like Procerin, this formula aims to prevent DHT-triggered hair loss, is believed to awaken dormant follicles for new hair, and may promote fuller, thicker, and stronger hair. Interestingly, the unnamed team behind this solution claims to have implemented a 2-step system in this formula. In particular, the first step involves interrupting alpha-5-reductase enzymes from binding to free testosterone (which prevents DHT production), while the second step, as hinted earlier, targets the hair follicles. Taking everything into account, this solution can potentially unveil results within two months. How? It’s all thanks to the combination of Pantothenic Acid (30mg), Biotin (200mcg), Millet (420mg), Maidenhair Fern (100mg), and L-Cysteine (6mg). 


  • Company: N/A 

  • Starting Price: $69 

Another hair supplement to have cut on the mere basis of popular demand, Restolin, is said to have been formulated by a 57-year-old William Anderson with over 30 years of experience delving into natural methods for healthy hair growth. Very little is known about how he developed this formula. Still, he does mention the power of vitamins and plants such as Vitamin C, Vitamin E, Beta Glucan, Pine Bark, Essiac Tea Complex, Quercetin, Arabinogalactan, Cat’s Claw, Lycopene, Graviola Leaf, Turmeric, Grape Seed, Mushroom Complex, Pomegranate, Olive, Garlic, Green Tea and Panax Ginseng. At present, the supplement’s fact has not been posted, nor do we know anything about the manufacturing company. Out of all the high-quality hair growth vitamins and supplements to choose from, some may gripe about the lack of information may hurt a relatively expensive formula at $69 per bottle. It is easy to see why some consumers shopping for the best supplements for hair growth might be on the fence about this product, but it is picking up steam in terms of notoriety and branding. There is a compelling video to watch about the formulation's beginning and why the creators think it is well on its way to being a top-rated hair growth vitamin formula on the market in 2021.  


  • Company: Valotin 

  • Starting Price: $22.95 to $73.48 

Valotin is a brand devoted to offering products that represent vitamins and botanical extracts that support hair strength and vitality. Whether women want a solution that promotes hair growth, preserves colored hair, or allows them to embrace their curls, Valotin claims to carry it all. Depending on the goal, any ingredients from B-Vitamin Complex, Chamomile, Aloe Vera, Fatty Alcohol, Vitamin A to Cucumber, Green Tea, and Alanine can be expected. Presently, the product options include Strengthening Shampoo and Conditioners, Hair Growth Support Supplements, Strengthening Serum, Daily Care, Nourished Inside and Out, and Deep Conditioning. 


  • Company: N/A 

  • Starting Price: $69 

Like Restolin, Revifol carries very little substance that explains the starting price of $69. James Connor is introduced in a video presentation, which suggests that a toxic enzyme causes hair loss. The recommended solution is Revifol, which has the potential to eliminate toxins and restore hair growth. The video presentation and written transcript of the Revifol supplement for supporting healthy hair growth spends a considerable amount of time elaborating about the benefits of "cocktail of ingredients" found in the product and how they are safe for consumption for anyone at any age. But with a little digging one can see there is not much to go on other than the word of a pen name spokesman named James Connor who is releasing this formula for "safety reasons against big pharm companies". While some might shy away from this natural hair growth vitamin supplement due to skepticism and lack of details, its recent surge in popularity helped it just make the cut of the best hair growth products to buy in 2021.  


  • Company: N/A 

  • Starting Price: $69 

Next is the most clinically researched hair growth supplement brand in Viviscal who formulated a maximum strength product that helps support and maintain normal healthy hair growth from within. With a wide selection of healthy hair growth vitamin supplements for men and women, it is voted the best hair growth vitamin formula on Amazon too. The advanced hair health solution is 100% drug-free and is scientifically formulated with a marine complex and collagen. The Viviscal for Women and Viviscal for Men hair growth product line looks to nourish thinning hair and promote hair growth naturally. There are numerous customer success stories and video testimonials of men and women using Viviscal hair growth supplements for real results too.

The Deciding Factors: How Does Your Hair Solution Rank? 

Now that we’ve introduced all hair supplements and products that made waves in 2021 (so far), it’s time we uncover our editorial team’s ranking criteria. It is important to note that these are basic requirements that everyone should be watchful of. Furthermore, this list can be easily customized to include preferred factors on an individualistic basis. Let’s cut right to the chase: 

Company Transparency 

With any good or service, the company responsible should own up to it. This usually reflects confidence in their solutions and the processes that brought us the final good. Most of the listed supplements have a strong company presence, where much emphasis has been placed on informing consumers and building trust relationships. Of course, those that cut popularity lacked a lot of that. In the former case, we knew how the company started, what their thought process involved, and the selected ingredients down to their concentrations. In the case where popularity stood out, information was either hidden or lacking substance. These differences alone suffice to help individuals identify potentially effective products from decoys set out by scammers. 

Scientifically Backed Ingredients 

Natural ingredients are starting to get acknowledged by society, but a lot of it has to do with science. If there’s scientific evidence that an ingredient can induce results, individuals are more likely to feel uplifted by it. For many people, traditional uses may either be equally important or even superior for that matter. However, to ensure maximum safety and reduced risk of experiencing side effects, we searched for products that toot both tradition and science equally (with slightly more support towards science). This level of confirmation and verification gives the most reassurance, especially seeing that many people are likely to take other medications and/or support systems. 

Concentration Per Serving 

Often, studies report dose-dependent effects for maximum results. Therefore, any quantities more or less may or may not be adequate if a company decides on a dose that is distinctive from what a study lists. More time may be required to see results, which is least desirable in severe hair loss. In keeping with everything thus far, many of our picks for brands highlighted the power of science. They went as far as reading through clinical trial results or conducting their own to evaluate performance. 

Advertised Benefits 

“Advertised benefits” as a factor was essential to introduce because some companies go as far as boasting unrealistic results. When a product is trusted to work from the inside and out, time makes all the difference. If results are stated to be obvious under a month, individuals should take it with a grain of salt. Hair follicles take time to strengthen, and this is equally applicable to graying and brittle hair, breakage, hair loss on the crown and temple areas, you name it. So, usually, when we see the possibility of immediate improvements with little to no evidence, the entire product is disregarded. 


With hair health, a solution must tend to the root causes. While temporary relief might be of interest to some, it can become costly and tedious. By figuring out the cause and dealing with it, individuals are less likely to spend more money in the future and are sure to understand what their bodies require for utmost wellness. Many of our listed companies devoted time to creating solutions that represent the whole-body nutritional approach, which has lasting effects all around. 


Uniqueness can be perceived as an extra factor that sets a company apart from the rest. For instance, supplement providers rarely conduct their clinical trials to see how effective the solution is. Instead, they rely on existing studies to generate a formula. In this case, a company that goes the extra mile to assess its solution is deemed a unique facet. Similarly, including patented ingredients, providing educational resources, and making quizzes accessible to narrow down options and understand wellness are stepping beyond the basic requirements. 

Money-Back Guarantee 

Not all solutions are one-size-fits-all; therefore, results are likely to vary from consumer to consumer. Matter-of-factly, in severe cases, it may feel as though no improvements have been witnessed. Companies tend to cover their solutions by a 30-, 60-, or 90-day money-back guarantee to protect consumers from the last consequence. Once again, this is not a requirement but a mere policy that reflects how confident a company is in the products they offer. 

Value for Price 

Finally, we have value for the price, which is always the last factor to study. For instance, a $69 product that checks off one of the listed criteria is far from valuable compared to another $69 product that checks off most of our factors. Undoubtedly, price alone depicts nothing unless we, as consumers, have a clear picture of the pros and cons of a product. In general, our goal was to ensure that a wide range of price points are available for all financial backgrounds. 

Let’s Talk Science: Do Hair Supplements Significantly Improve Hair Quality? 

At first glance, consumers are likely to feel overwhelmed by the length of this guide. But, as each piece of information is absorbed, more clarity will have been established. The same applies to the ingredient list. Most of the listed companies have taken the extensive route of including several ingredients. Seeing paragraphs and paragraphs of different ingredients will be tedious until some foundational knowledge is present. 

Accordingly, our editorial team spent some time diving into the scientific community's role in bringing to light effective ingredients from the ineffective. To keep things simple, we stuck by the commonly recurring ingredients across all brands. That said, we actively encourage people to do thorough analyses on the desired product before finalizing their decisions! 

Saw Palmetto 

Saw palmetto is a type of palm that grows mainly in the coastal regions of the Southern United States. As stated by one source, promising research has proven it as potentially likely to improve prostate and urinary health, reduce inflammation, and prevent hair loss [2]. Speaking of hair health, we stumbled upon another piece that questioned Dr. Joshua Zeichner, Director of Cosmetic and Clinical Research in Dermatology, on all matters related to Saw palmetto ingestion [3]. In it, the expert explained that this particular ingredient is known to influence the 5-alpha reductase enzyme, one that has been known to convert testosterone into DHT. 

DHT is the culprit to watch out for those unfamiliar with the hormone, as it is responsible for male and female pattern hair loss. In addition, he noted that Saw palmetto’s ability to target androgen hormones is what has many people retorting to it. In other words, high levels of androgen hormones have been linked to hair thinning. He recommends capsules over topical treatments regarding its uses unless the latter are left for long periods. He also stressed pregnant or breastfeeding women to shy away from as their hair loss concerns are probably driven by pregnancy. 


Also referred to as vitamin B7, biotin helps digest carbohydrates and amino acids while contributing to fatty acids and glucose production. In a piece compiled by WebMD, plastic surgeon and hair restoration specialist Gary Linkov, MD’s opinion was sought. Interestingly, the expert explained that “Biotin supplementation may be helpful for people who are truly biotin-deficient, but biotin deficiency is quite rare amongst the general population.” With the latter in mind, one possible reason biotin is consumed is to help strengthen hair so that it is more resistant to falling out [4]. 

A 2017 systematic review [5] that looked at available literature on biotin efficacy on hair and nail growth insists that more research is needed on its ingestion. Despite increased uses, very little demonstrating its effectiveness is available. This, according to the team, limits our understanding of how biotin deficiency even takes form and issues about brittle nail syndrome/uncombable hair. Bearing the latter in mind, the researchers also pinpointed that such consequences rarely affect healthy individuals. Still, once again, more studies that factor health into the equation are warranted. 

Hydrolyzed Collagen 

Hydrolyzed collagens are broken down into dissolvable amino acids for increased bioavailability and have been shown to support skin, nails, and joints health, among others. According to Nutrafol’s Dr. Melissa Anzelone, ND, collagen supplements help the digestive tract healing and protecting the gut. In so doing, an immediate consequence is allegedly increased protein absorption, and hence, healthier hair. She also explained that collagen works synergistically with hyaluronic acid to moisturize and rebuild the dermis structure surrounding our hair follicles [6]. 

In the same piece where Dr. Anzelone shared the moisturizing effects of collagen, Dr. Julie Russak, brand ambassador for NeoCell, noted its hair growth potential. As per the specialist, incorporating “a daily collagen supplement can also aid in hair regrowth, as hair health starts from the inside.” This comes after her lengthy discussion on causes for poor health, including “iron deficiency, auto-immune diseases, low thyroid, hormonal imbalances and the natural production of hormone dihydrotestosterone (DHT) [6].” 


Keratin is a fibrous structural protein found in the skin, nails, hair, and specific internal organs and glands. While we scavenged our resources for keratin supplementation, we stumbled upon one study that looked at the effects of a natural keratin hydrolysate called Kera-Diet®. Given that keratin hydrolysate is the closest to keratin supplements we can find scientifically, we read further into the study. Sixty women were given the supplement for 90 days, taking 45- and 90-day measurements. In the end, daily oral supplementation of 1000mg is said to have improved both hair and nail conditions. Furthermore, its ingestion led to a positive impact, highlighting the power of essential nutrients on both the acute form of telogen effluvium (i.e., a type of hair shedding) and brittle nail syndrome (i.e., ragged, thin, and dull-looking nails) [7]. 


Methylsulfonylmethane (MSM) is a chemical found in certain plants, animals, and the human body. Typically, MSM is integrated within joint health supplements to ease symptoms linked to osteoarthritis, rheumatoid arthritis, bursitis, or tenosynovitis, among others [8]. However, more recently, other uses have taken form. One team of researchers curious to see how MSM can lend a helping hand in improving skin, nails, and hair health conducted a double-blind clinical study, where participants either ingested 1- or 3-grams of MSM per day. 

By the end, they reported improvements in hair and nail conditions, adding that “the higher concentration (3g/day) of MSM delivered quicker and stronger benefits, as compared to the lower concentration (1g/day).” The reason gathered for such benefits was linked to its action on keratin, which, as discussed earlier, is a protein that serves as a building block for hair and nails [9]. 

Vitamin A 

Vitamin A is the name given to a group of fat-soluble retinoids that serve many roles in the body. A surprising factor worth mentioning about this vitamin is that taking it in excess could give rise to hair loss. This was the case for a 28-year-old who took a daily dose of Vitamin A (5000IU), which led her serum levels to rise well above average (140ug/dL), leading to poor hair health. Mind you that this is just one case reported in 1979, so recommendations have changed. At present, the recommended daily limit is approximately 10,000IU, and anything above the threshold might lead to vitamin A toxicity [10]. 

Vitamin C 

Vitamin C or ascorbic acid is a water-soluble vitamin known for its increased antioxidant concentration. The latter is what prevents damages caused by oxidative stress and free radicals. As for its inclusion in hair supplements, one source simply noted that it is crucial for collagen production. This, as mentioned above, contributes to not only hair structure but also moisture levels and hair growth. Moreover, vitamin C helps with nutrients absorption, one of them being zinc, which we will be diving into shortly [11]. 


Iron is a type of mineral that is naturally found in many of the foods we eat. It is a vital component for hemoglobin's red blood cell protein, responsible for transferring oxygen from the lungs to tissues [12]. So, what role does iron play in hair health? It turns out that its contribution to hemoglobin is crucial because it delivers essential nutrients and oxygen to our hair cells, consequently promoting hair growth. When this process is halted or disrupted – one cause being an iron deficiency – hemoglobin levels will be negatively affected, forcing hair loss concerns to rise. The consequences above are what we see as traditional male and female pattern baldness [13]. 


Zinc is a chemical that has been linked to balanced immune function and blood sugar levels, all while promoting healthy skin, eyes, and heart health [14]. That said, one group of researchers curious to see whether the therapeutic effects of oral zinc supplementation on patients with alopecia areata were helpful enough conducted a thorough study. After administering 50mg per day for 12 weeks, the researchers concluded a significant increase in serum zinc levels, adding that 66.7% of patients experienced positive therapeutic effects. Seeing these results, they commented that they could see zinc supplementation as “an adjuvant therapy for the alopecia areata patients with a low serum zinc level and for whom the traditional therapeutic methods have been unsuccessful [15].” 


Reynoutria multiflora or Fo-Ti is a species of flowering plants belonging to the Polygonaceae buckwheat family. As for its mechanism, one source believes that it works by altering bodily chemicals linked to anti-aging effects, which might explain why it appears several times in hair supplements. To be more specific, Fo-Ti could potentially increase the number of hair follicles, stimulate hair growth, and prevent premature graying of hair [16]. Most existing studies on Fo-Ti and hair are early research and warrant further investigation regarding its potential, risks, and side effects. 

Hair Growth Supplements FAQS 

Q: What are hair follicles? 

A: A hair follicle is a tunnel-shaped structure located at the outer layer of our skin. Through this tunnel (i.e., the scalp possesses thousands of them), strands of hair grow. The root of our hair is made up of essential nutrients, proteins, and oxygen crucial for their strength and wellness. Therefore, a deficiency in any one of its growth-inducing factors can lead to weak hair [17]. 

Q: On average, how many strands of hair are lost per day? 

A: On average, it is customary to lose anywhere between 50 and 100 strands of hair per day. This applies to both men and women. Every month, hair grows an average of one centimeter, and a single scalp hair grows continuously for two to six years before taking a complete break of four months. After the break, hair tends to fall out, and new hair comes out, repeating the hair growth cycle [18]. 

Q: How many stages does our hair cycle go through? 

A: The hair cycle consists of three stages of growth and shedding, referred to as anagen, catagen, and telogen. Anagen is the first stage and is accepted as the active growth phase. Up next, we have catagen, commonly recognized as the stage in which less than 1% of our hair enters. This is where the hair follicle stops producing fiber and regresses, shrinking it dramatically. Finally, we have telogen, where our hair growth cycle takes a break and awaits the anagen phase to take shape so that hair can be pushed out of its follicle [19]. 

Q: How do I know the cause of my hair problem? 

A: There are many causes for hair problems, and deciphering the exact one can be difficult on one’s own. For this reason, it might be best to sit down with a family doctor to get a recommendation for a trichologist, i.e., a specialist in hair and scalp-related problems. The latter can be thought of as an extra step involving several tests to see whether one’s hair problem is severe or not [20]. 

Q: What is the best way to eliminate split ends? 

A: Split ends can be avoided by taking fewer showers, getting in more haircuts, and resorting to hair products free from harsh ingredients. From time to time, applying a hair mask can also help with split ends and, to some extent, breakage. 

Q: What does a greasy scalp suggest? 

A: An excessively greasy scalp implies over-reactive sebaceous glands on the scalp. This is unfavorable, as grease attracts dirt easily, increases dandruff production, and leaves our hair strands stuck to one another. Oil production can clog hair roots when proper care is not sought, further worsening the consequences [21]. 

Q: How often should hair be washed? 

A: On average, hair should be washed once every 2 or 3 days. There’s no one-size-fits-all recommendation, as it boils down to grease level, odor, presence of dandruff, and other factors that might cause discomfort in consumers. 

Q: Why does dandruff take form? 

A: One cause of dandruff is oily skin. Others include the irritated scalp, not shampooing enough, increased yeast-like fungus that feeds on scalp oils, sensitivity to hair care products, dry skin, etc. Mayo Clinic listed age, gender (men tend to produce more dandruff), and certain illnesses as risk factors to be watchful of [22]. 

Q: What are some general hair conditions? 

A: There are several known hair conditions/disorders that consumers need to be aware of. Some worth digging further into are androgenetic alopecia, alopecia areata, scarring alopecia, telogen effluvium, anagen effluvium, congenital hypotrichosis, tinea capitis, folliculitis, trichotillomania, loose anagen syndrome, and monilethrix. 

Q: How realistic is it to assume hair will regrow without surgery? 

A: It is realistic to reverse hair loss without surgery. The FDA has since approved two drugs for treating male pattern baldness, including Rogaine (Minoxidil) and Propecia (Finasteride). The former is available over the counter (OTC), while the latter can only be accessed via a doctor’s prescription. 

Q: Is it safe to take hair supplements? 

A: Generally speaking, hair supplements are safe to ingest because of their all-natural ingredients. However, this is not to say that medication interaction and side effects aren’t possible. We encourage consumers to discuss the potential impact of taking hair supplements with a specialist or thoroughly analyze each ingredient before implementing it for everyday use to avoid negative consequences. 

Q: Do all hair supplements work? 

A: No, not all hair supplements are made equally; therefore, a careful investigation is needed before falling for any claims. Presently, there are only a certain number of all-natural ingredients proven to promote hair health. It might be a good idea to refer to our top picks in this piece! 

Q: How long will it take to see results with hair supplements? 

A: Results come to those who are consistent with the recommended serving sizes. From what our editorial team noticed, individuals are asked to be consistent for at least six months to see its full effects take form. 

Q: To what extent do hair vitamins work? 

A: Hair vitamins/supplements should be considered extra measures that deliver essential nutrients to our hair cells. Some are likely to work more than others. Based on existing research, the best hair vitamins include Vitamin A, B-Vitamins, Vitamin C, Vitamin D, Vitamin E, Iron, Zinc, and some form of the protein [23]. Others are gradually being introduced to society, as clearly reflected in our top picks. 

Q: Do hair supplements work on all types of hair? 

A: Yes, most if not all hair supplements consider all hair types. Though, to be sure, we ask that everyone confirms what the creators of a particular solution recommend for maximum results. 

The Top Hair Growth Products in 2021 Final Verdict 

Ultimately, hair care is as critical as any other part of the body. When taken too lightly, our scalps might be consumed by harmful bacteria, allowing them to make their way to the rest of the bodies. Seeing that hair is used as a statement, and to a large extent, makes up one’s identity, including hair supplements, can help prolong undesirable effects such as hair loss, thinning, breakage, frizz, split ends, and many others. It is essential to point out that hair supplements do not cure an underlying condition/disease; instead, they simply target hair. Whether the root cause has been emphasized or not depends on the company behind a particular solution, but ideally, the whole-body nutritional approach is taken for complete wellness. Finally, it might be worth reassessing one’s eating habits and lifestyle habits to promote wellness all around as hair growth is often an indicator of an internal paradise equals an external reflection.  

A specialist’s opinion should be sought for severe hair problems, as they can suggest multiple tests done on hair and scalp health to arrive at the bottom of things. With everything, individuals need to be careful when selecting a hair supplement, as some solutions are neither effective nor created with the best intentions. As all consumers can see throughout this review of the best hair growth products, we've uncovered a handful of in-demand popular supplements that hav little to no substance or zero evidence to back up its hair regrowth claims and results.  

But one thing is for sure, out of the hundreds of available hair growth vitamins to buy in 2021, these are without a doubt the strongest and most effective hair growth products on the market this year: 

The following research, reviews and recommendations of the best hair growth vitamin supplements will be continually updated once new products and formulas become available and make the final cut to be added to the lustrous list of finalists mentioned above. Once more details are available and come back there will be the latest updates integrated about the best hair growth products to use in 2021 based on what the customers are saying.
