Facial hair is hair grown on the face, usually on the chin, cheeks, and upper lip region. It is typically a secondary sex characteristic of human males. Men typically start developing facial hair in the later stages of puberty or adolescence, at around fourteen years of age, and most do not finish developing a full adult beard until around sixteen or later. However, large variations can occur; boys as young as ten have also been known to develop facial hair, [1] and some men do not produce much facial hair at all.

Men may style their facial hair into beards, moustaches, goatees or sideburns; many others completely shave their facial hair and this is referred to as being "clean-shaven". The term whiskers, when used to refer to human facial hair, indicates the hair on the chin and cheeks. [2]

Women are also capable of developing facial hair, especially after menopause, though typically significantly less than men. Women with lots of facial hair, the extreme being bearded ladies, have been considered as freaks by society and sometimes been part of circuses. Trans men typically develop more facial hair while undergoing masculinizing hormone therapy as part of their wider gender transition. [3]

History

In the West in the nineteenth century, most men maintained some facial hair. According to a 1976 study by University of Washington economist Dwight Robinson, who reviewed illustrations in the Illustrated London News , facial hair peaked in the 1880s (90%). The wearing of beards dropped significantly, although mustaches remained popular until the 1940s. [4]

In male adolescence

The moustache forms its own stage in the development of facial hair in adolescent males. [6] Facial hair in males does not always appear in a specific order during puberty and varies but may follow this process. Boys today since 2010 have started puberty at 11 while boys in the 1970s didn't began to develop until age 12, today youths experience facial hair a year earlier than males in the 1970s  :

Although this order is commonly seen, it can vary widely, with some facial hair starting from the chin and up towards the sideburns. As with most human biological processes, this specific order may vary depending on one's genetic heritage or environment.

Military

Depending on the periods and countries, facial hair has been prohibited in armies 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, numerous prophets mentioned in the Abrahamic religions (Judaism, Christianity and Islam) were known to grow beards. Sikhism mandates growing beards; in Shia Islam, trimming beards is allowed but shaving them is forbidden. 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. In Sikhism, one of the Five Ks followed by Khalsa Sikhs is kesh, which forbids the cutting or shaving of hair, both scalp and facial.

On women

Women 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. 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 means of electrolysis (permanent) or laser hair removal (semi-permanent).

In non-human great apes

Adult orangutans have varying degrees of facial hair. In chimpanzees and gorillas, 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.

Primates

Primates such as the bearded emperor tamarin have what look like whiskers.

Body hair or androgenic hair is terminal hair that develops on the human body during and after puberty.

Human body shape is a complex phenomenon with sophisticated detail and function. The general shape or figure of a person is defined mainly by the molding of skeletal structures, as well as the distribution of muscles and fat. Skeletal structure grows and changes only up to the point at which a human reaches adulthood and remains essentially the same for the rest of their life. Growth is usually completed between the ages of 13 and 18, at which time the epiphyseal plates of long bones close, allowing no further growth.
