Facial hair is a secondary sex characteristic of human males. Men typically start developing facial hair in the later years of puberty or adolescence, between seventeen and twenty years of age, and most do not finish developing a fully adult beard until their early twenties or later. This varies, as boys may first develop facial hair between fourteen and sixteen years of age, and boys as young as eleven have been known to develop facial hair. In addition, the patches of hair can vary between bushy and bristly. Women are also capable of developing facial hair, especially after menopause, though typically significantly less than men.
Male pogonotrophy (the growing of facial hair; i.e., beardedness) is often culturally associated with wisdom and virility. Men may style their facial hair into beards, moustaches, goatees or sideburns; others completely shave their facial hair. The term "whiskers," when used to refer to human facial hair, indicates the hair on the chin and cheeks.
