Facial hair is a
secondary sex characteristic in human
males. Many
men develop facial hair in the later years of
puberty, approximately between 15-18 years old. This can vary, however, and males as young as 11 have been known to develop facial hair that require routine shaving. Further, many
women also have some facial hair, especially after
menopause, though typically much less than men.
Eyebrows and
eyelashes are also grown by both sexes of all ages. Male pogonotrophy (the growing of facial hair; i.e, beardedness) is often culturally associated with wisdom and
virility. Many men style their facial hair into
beards,
moustaches,
goatees or
sideburns. However, many others completely
shave their facial
hair. Although only certain nonhuman mammals have true sensory whiskers, a man's facial hair, especially short hairs that were missed in shaving, is often referred to as whiskers.
