Military{{main article|Facial hair in the military}}Depending on the periods and countries, facial hair was prohibited in the army or, on the contrary, an integral part of the uniform. In religionsMany 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, mandate growing beards. Amish men grow beards after marriage, but continue to shave their moustaches in order to avoid historical associations with military facial hair due to their pacifistic beliefs. On womenWomen typically have little hair on the face, apart from eyebrows and the vellus hair that covers most of the body. 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 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. Many women globally choose to totally remove their facial hair by professional laser treatment.

In chimpanzees and bonobos, facial and body hair become sparser in adulthood due to the aging process, which is in stark contrast to humans, whose facial and body hair become stronger. Because infant great apes have thicker "facial" (as well as body) hair than their older counterparts, it is not androgenic but part of the fur complex. The sensitivity to androgens seems to have been acquired by humans on the gene KRT37 relatively recently. See also
