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.
In male adolescence 
The moustache forms its own stage in the development of facial hair in adolescent males. Facial hair in males does not always appear in a specific order during puberty and varies among some individuals but 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.
- Although this order is commonly seen, it can vary widely, with some facial hair starting from the chin and up towards the sideburns.
Depending on the periods and countries, facial hair was prohibited in the army or, on the contrary, an integral part of the uniform.
In religions 
Many religious male figures are recorded to have had facial hair; for example, all the prophets mentioned in the Abrahamic religions (Judaism, Christianity and Islam) were known to grow their beards. Other religions, such as Sikhism, encourage growing beards. Some scholars among Sunna Muslims see growing the beard to be a compulsory act as it was adopted by the Prophet Mohammed himself to help distinguish fellow Muslims from spys and transgressors during times of war. Amish men grow beards after becoming married, but continue to shave their moustache in order to avoid historical associations with military facial hair due to their pacifistic beliefs.
On 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, most commonly after menopause. Excessive hairiness (especially facially) is known as hirsutism, and is usually an indication of atypical hormonal variation. In contemporary Western culture, many women shave, tweeze, or otherwise depilate facial hair that appears, as considerable social stigma is associated with facial hair on women, and freak shows and circuses have historically displayed bearded women. in the western culture, many women choose to totally remove their facial hair by professional laser treatment.
