Reasons for Removing Hair

Hair removal has been practised for centuries in almost all human cultures. The methods used vary among times and regions, but shaving is the most common method.

Medical reasons

In Ancient Egypt, many people depilated their entire bodies to prevent infestation by lice, fleas, and other parasites. Ancient Egyptian priests also shaved or depilated all over daily, so as to present a 'pure' body before the images of the gods.

Patients' body hair was once shaved before surgery for reasons of hygiene; however, this turned out to be counterproductive and, as a result, in many hospitals patients are no longer shaved. The shaving of hair has sometimes been used in attempts to eradicate lice or to minimize body odor due to accumulation of odor-causing micro-organisms in hair. Some people with trichiasis find it medically necessary to remove ingrown eyelashes. Incorrect shaving (shaving against the grain) can often cause ingrown hairs.

Many forms of cancer require chemotherapy, which often causes severe and irregular hair loss. For this reason, it is common for cancer patients to shave their heads even before starting chemotherapy.

Social, cultural, or sexual reasons

A female body devoid of bodily hair, combined with luxuriant tresses was a 19th-century theme: Birth of Venus by William-Adolphe Bouguereau, 1879.Hair is normally removed for social and sexual reasons related to the social role of hair in human society. Many cultures have an aesthetic "ideal" amount of hair for males and females. People whose hair violates such standards may experience real or perceived problems with social acceptance.

Many men in Western cultures shave their facial hair, so only a minority of men have a beard, even though fast-growing facial hair must be shaved daily to achieve a clean-shaven or hairless look. Some men shave because they cannot grow a "full" beard (generally defined as an even density from cheeks to neck), because beard color is different from scalp hair color, or because it grows in many directions, making a groomed look difficult. Some men shave because their beards are very coarse, causing itchiness and irritation. Some men grow a beard from time to time to change their appearance.

In many cultures, particularly North American and Western European, it became increasingly common during the 20th century for women to remove some or all of their body hair, due to societal values that consider it unattractive and/or not feminine (see gender role), or as a matter of practising good hygiene. People may also remove some or all of their pubic hair for aesthetic or sexual reasons. Adult film stars are well known for this practice. Men may also practice this, but not as commonly. In a sexual context, pubic hair removal is done to increase visual exposure of the genitalia and/or facilitate access to the genital area by removing the barrier of hair.

Some women in Western cultures choose not to remove hair from their bodies as an act of defiance against what they believe to be an oppressive ritual. Others choose not to remove hair simply because they have no desire to.

Some men shave their heads, either as a fashion statement, because they find a shaved head preferable to the appearance of male pattern baldness, or in order to attain enhanced cooling of the skull (particularly for people suffering from hyperhidrosis). A much smaller number of women also shave their heads as fashion or political statements.

Some women also shave their heads for cultural or social reasons. In India , tradition required widows in some sections of the society to shave their heads as part of being ostracized, the outlawed custom is still infrequently encountered mostly in rural areas, the society at large and the government are working to end the practice of ostracizing widows.

In art paintings or carvings from ancient times, one can often see women portrayed with no pubic hair: pubic hair was linked to sexual acts and desires in the general mindset, and thus it was deemed improper and impure in a public painting. This may have influenced aesthetic views regarding the matter as well.

Male-to-female gender reassignment

Male-to-female transsexual women who are preparing for sex reassignment surgery usually remove their facial beard hair, typically either by electrolysis or laser, or a combination of the two procedures. While this is commonly done entirely before surgery, some patients will start the procedure before surgery, and finish a few months to several years afterwards, often due to cost.

In addition, it is recommended by some surgeons that part of the pubic hair be removed prior to surgery as well, usually by electrolysis. Since the neovagina is created using the skin of the penis and part of the scrotum, which usually has active follicles, the hair is removed from these areas prior to surgery, in order for the genitals to be fashioned without the concern of hair growth inside of the neovagina. In some cases, the surgeon scrapes the underside of the skin to remove the follicles at or near the beginning of the surgery, eliminating any need for pre-surgical hair removal.

For religious reasons

Head-shaving is a part of some Buddhist, Christian, Muslim, Jain, Jewish and Hindu traditions. Buddhist and Christian monks generally undergo some form of head-shaving during their ordination; in Thailand monks shave their eyebrows as well. Brahmin children have their heads ritualistically shaved before beginning school.

In some parts of the Theravada Buddhist world, it is common practice to shave the heads of children. Weak or sickly children are often left with a small topknot of hair, to gauge their health and mark them for special treatment. When health improves, the lock is cut off.

In Judaism, men are prohibited to shave the beard and sideburns using a blade against the skin. However, electric razors may be used, since the cutting blade does not directly touch the skin. Women are allowed to shave their heads; in some Hasidic circles, married women traditionally shave their heads since they are prohibited to expose their hair to men other than their husbands and families.

The Bahá'í religion explicitly prohibits head-shaving. Sikhs take an even stronger stance, opposing all forms of hair removal. One of the Sikh "Five Ks" is Kesh, meaning "uncut hair". To Sikhs, the maintenance and management of long hair is a manifestation of one's piety.

Muslim law (Sharia) puts hair in three categories: that which it is recommended to remove (pubic and armpit hair), that which it is recommended to keep (the beard), and that which is the object of limited recommendation (foot, hand, back, and chest hair). Removal of armpit and pubic hair is a hygienic practice which was taught by Muhammad and which was enumerated as having been part of practices conforming to man's premortal (Fitrah) nature. On the other hand, shaving or removing part of the eyebrows is forbidden as the "modification of the creation of Allah and obedience to Satan in his work to fool men and bring them to modify the creation of Allah." Stray hairs between the eyebrows may be removed, but not the hairs of the eyebrows. A male may trim or cut hair on his head—however shaving of the head is forbidden in some branches of the religion. A male may trim hair on the chest and back but may not remove it, as this is considered to be imitating women. In contrast, women are permitted to remove hair from these areas. In the 9th century, the use of chemical depilatories for women was introduced by Ziryab in Al-Andalus.
