Armpit hair was here since the beginning of a human race. When exactly that was is another story. But no matter if we want it or not armpit hair is growing like any other hair on our body.

Armpit hair theories

There are two main reasons why we have hair in our underarms. The first and probably the main reason is that armpit hair collect our pheromones. Yeah, pheromones cause that smell when we get sweaty. Some people, usually men, have stronger pheromones hence their armpits smell really bad. There is a myth that if you shave off your armpit hair you won’t smell so much. Not true, hair itself doesn’t smell. It’s those pheromones that produce the smell, hair is only means how they get out of the body.

Second theory suggests that armpit hair helps to lessen the friction on the sking when we move our arms. I’m not sure how true this is because I don’t know anyone with shaved armpits who would have problems with friction.
