Hair removal

Hair removal, also known as epilation or depilation, is the deliberate removal of body hair or head hair.

Not to be confused with Hair loss.

Hair typically grows all over the human body and can vary in thickness and length across human populations. Hair becomes more visible during and after puberty and men tend to have thicker, more visible body hair than women.[1] Both males and females have visible body hair on the head, eyebrows, eyelashes, armpits, genital area, arms, and legs. Males and some females may also have thicker hair growth on their face, abdomen, back, buttocks, anus, areola, chest, nostrils, and ears. Hair does not generally grow on the lips, back of the ear, the underside of the hands or feet, or on certain areas of the genitalia.


Hair removal may be practiced for cultural, aesthetic, hygienic, sexual, medical, or religious reasons. Forms of hair removal have been practiced in almost all human cultures since at least the Neolithic era. The methods used to remove hair have varied in different times and regions.


The word "depilation" comes from the Latin "pilus" which means "hair".

Other reasons[edit]

Religion[edit]

Head-shaving (tonsure) is a part of some Buddhist, Christian, Muslim, Jain and Hindu traditions.[26] Buddhist and Christian monks generally undergo some form of tonsure during their induction into monastic life.


Within Amish society, tradition ordains men to stop shaving a part of their facial hair upon marriage and grow a Shenandoah style beard which serves the significance of wearing a wedding ring, moustaches are rejected as they are regarded as martial (traditionally associated with the military).[27]


In Judaism (see Shaving in Judaism), there is no obligation for women to remove body hair or facial hair, unless they wish to do so. However, in preparation for a woman's immersion in a ritual bath after concluding her days of purification (following her menstrual cycle), the custom of Jewish women is to shave off their pubic hair.[28] During a mourning ritual, Jewish men are restricted in the Torah and Halakha to using scissors and prohibited from using a razor blade to shave their beards or sideburns,[29] and, by custom, neither men nor women may cut or shave their hair during the shiva period.[30][31]


The Baháʼí Faith recommends against complete and long-term head-shaving outside of medical purposes. It is not currently practiced as a law, contingent upon a future decision by the Universal House of Justice, its highest governing body. Sikhs take an even stronger stance, opposing all forms of hair removal. One of the "Five Ks" of Sikhism is Kesh, meaning "hair".[32] Baptized Sikhs are specifically instructed to have unshorn Kesh (the hair on their head and beards for men) as a major tenet of the Sikh faith. To Sikhs, the maintenance and management of long hair is a manifestation of one's piety.[32]


The majority of Muslims believe that adult removal of pubic and axillary hair, as a hygienic measure, is religiously beneficial. Under Muslim law (Sharia), it is recommended to keep the beard. A Muslim may trim or cut hair on the head. In the 9th century, the use of chemical depilatories for women was introduced by Ziryab in Al-Andalus.

Depilation is the removal of the part of the hair above the surface of the skin. The most common form of depilation is or trimming. Another option is the use of chemical depilatories, which work by breaking the disulfide bonds that link the protein chains that give hair its strength.

Advantages and disadvantages[edit]

There are several disadvantages to many of these hair removal methods.


Hair removal can cause issues: skin inflammation, minor burns, lesions, scarring, ingrown hairs, bumps, and infected hair follicles (folliculitis).


Some removal methods are not permanent, can cause medical problems and permanent damage, or have very high costs. Some of these methods are still in the testing phase and have not been clinically proven.


One issue that can be considered an advantage or a disadvantage depending upon an individual's viewpoint, is that removing hair has the effect of removing information about the individual's hair growth patterns due to genetic predisposition, illness, androgen levels (such as from pubertal hormonal imbalances or drug side effects), and/or gender status.


In the hair follicle, stem cells reside in a discrete microenvironment called the bulge, located at the base of the part of the follicle that is established during morphogenesis but does not degenerate during the hair cycle. The bulge contains multipotent stem cells that can be recruited during wound healing to help repair the epidermis.[61]
