Let’s face it, the vast majority of people who both go bald and have beards are men. Is this a coincidence?
These scientists think not! In fact, they believe that the reason men go bald is to compensate for the heat they retain by growing a beard. In support of this idea, their study from 1988 found that the area of skin covered by men’s beard hair correlates with the area of skin with sweat glands on the forehead and calvaria (the top of the head).
