Facial hair is a secondary sex characteristic in human males. Many men start developing facial hair in the later years of puberty, approximately between 18-20 years old and most men don't finish developing a fully adult beard until their early 20s or even later.[1] This can vary, however, and males as young as 11 have been known to develop facial hair that requires routine shaving. In addition, the patches of hair can vary between bushy and bristly. Furthermore, many women also have some facial hair, especially after menopause, though typically much less than men.

Abraham Lincoln was said to have grown a beard because an 11-year-old girl named Grace Bedell wrote to him, saying that he would look better with one

Male pogonotrophy (the growing of facial hair; i.e, beardedness) is often culturally associated with wisdom and virility.[2] Many men style their facial hair into beards, moustaches, goatees or sideburns. However, many others completely shave their facial hair. The term "whiskers", used when referring to human facial hair indicates the hair on the chin and cheeks.[3]

[edit] In male adolescence

The moustache forms its own stage in the development of facial hair in adolescent males.[4] Facial hair in males does not normally appears in a specific order during pubertybut may follow this process:

  • The first facial hair to appear tends to grow at the corners of the upper lip,
  • It then spreads to form a moustache over the entire upper lip,
  • This is followed by the appearance of hair on the upper part of the cheeks, and the area under the lower lip,
  • It eventually spreads to the sides and lower border of the chin, and the rest of the lower face to form a full beard.

As with most human biological processes, this specific order may vary among some individuals.

[edit] In women

Women typically have little hair on their faces, apart from eyebrows and the vellus hair that covers most of their bodies. However, in some cases women have noticeable facial hair growth. Excessive hairiness (especially facially) is known as hirsutism, and is usually an indication of abnormal hormonal variation. In contemporary western culture, many women shave, tweeze or otherwise depilate facial hair which does appear, as there is considerable social stigma associated with facial hair in women.
