Why do guys go bald on their heads but can have beards?
My boyfriend is going bald but he doesn't seem to have a problem growing facial hair on his chin. Why do guys seem to do that? My principal is REALLY bald but has a beard, too. Is that normal? Does their hair just stop growing on their heads and grow more on their face then?

Well, without getting too technical, the reason men who go bald seem to have no problem growing beards is, testosterone.
Facial hair and scalp hair are different types of hair entirely. So, its not a matter of "wearing out the follicles" with brushing. Men can go bald for several different reasons, but one very common reason is that in some men they carry a gene that causes their bodies to convert testosterone to a substance called DHT which damages the follicles on their scalp. The more testosterone they have, the balder they can be.
(Which could also explain why women tend to be so forgiving of a bald head on men, bald men tend to have more testosterone, which women find sexy)
However, facial hair grows because of testosterone. Which is why men only begin to grow it at puberty. The more testosterone, the more facial hair. So, what causes lots of facial hair in some men, can actually reduce their hair on top, if they also have the baldness gene that causes the production of DHT.
So, no, they dont grow more facial hair because they are bald, it all boils down to testosterone and that gene that causes it damage scalp follicles when it is converted to DHT. If they had high testosterone but did not carry the gene, they would have plenty of hair on their heads and on their chins.

the difference between the hair on your head and the hair on your face, (when it comes to males) is that even if they don't do as much with their hair as girls do, they still fool around with it a lot. and as they get older, the hair follicles become weaker from age, especially with men, and they eventually give up and stop growing the hair. with the hair on their faces, they don't mess with it a lot. they don't shampoo it and comb it and gel it. and even so, the hair on your head is a lot more fine then the hair on your face. thats why when they havent shaved in a while, its really prickly and almost painful.
hope this helped. :)
