How functional/necessary is armpit hair?
I'm curious, how functional or necessary is armpit hair?
Armpit hair is a natural occurrence in humans, and it does serve some purposes. For example, it can help to wick moisture away from the skin and reduce friction between the skin and clothing. It can also help to trap and hold onto pheromones, which can play a role in attracting potential mates.
