is a secondary sex characteristic
of human males
typically start developing facial hair in the later years of puberty
, 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.
