Well, im a guy and i have long hair.
my parents keep telling me that guys can’t have long hair or it will lead to baldness from the weight of it pulling on it. i don’t put in a ponytail or anything that would cause any real pulling on it.
this sounds like a load of crap to me, like one of those myths parents tell their kids to scare them into doing what they want. they never did that to me when i was younger, and i don’t see why they would start now considering im about a year and a half from being a legal adult.
the way i see it, nature intended everyone to have long hair, thats why everyone’s hair grows long rather than staying short. animals that have fur are meant to be short haired, so their hair doesn’t grow long.
so does long hair on guys cause baldness?
