evolution of human hair

I know what it is like to inhale hair: I regularly experience it while, er, vigorously exercising with my girlfriend but I manage to continue to get enough oxygen to, er, complete the workout. Sometimes.Maybe your own male hair is much coarser Truthlover!I actually heard that Asian hair is round (and hence straight) and the curliest hair is asymetrical.What the heck is with balding then? Where does that fit in with evolution?And why do women find completely shaven more appealing than the monk (semi-bald) look?

Brian might have hit the nail on the head (indirectly). Obviously hormones paly a role with not only hair quantity and distribution (between the sexes) but also with variances between the same sex. It is a hormone (linked to testosterone) that cause male pattern baldness: indeed you can stop a person who is predisposed to balding going bald by hormone treatment or castration (a bit extreme). Guys who are overweight and drink heavily have higher levels of estrogen and lower testosterone and therefor are less likely to rapidly lose hair.Similarly guys with higher testosterone grow facial hair faster.Testosterone levels are not only genetic but as I indicated above, lifestyle/health related. Bodybuilders produced (naturally and artifically) lots of it and often go bald.Maybe head hair growth compensated for the loss of bodyhair in hominids associated with the use of clothing. Dunno.
