Hair removal
Résumé
Hair removal, also known as epilation or depilation, is the deliberate removal of body hair or head hair.
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.
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".
For centuries, hair removal has long shaped gender roles, served to signify social status and defined notions of femininity and the ideal "". In early periods, the condition of being hairless was mostly done as a way to keep the body clean, using flint, seashells, beeswax and various other depilatory utensils and exfoliator substances, some highly questionable and highly caustic. Ancient Rome also associated hair removal with status: a person with smooth skin was associated with purity and superiority. Removing body hair was done by both men and women.
In Ancient Egypt, besides being a fashion statement for affluent Egyptians of all genders, hair removal served as a treatment for louse infestation, which was a prevalent issue in the region. Very often, they would replace the removed head hair with a Nubian wig, which was seen as easier to maintain and also fashionable. Ancient Egyptian priests also shaved or depilated all over daily, so as to present a "pure" body before the images of the gods.

Rasage
thumb|right|280px| Le Barbier du Souk (1897) de Enrique Simonet thumb|280px|Un homme se rasant avec un rasoir droit. Le rasage est une technique et un soin d'épilation temporaire basé sur l'usage d'un rasoir. Chez les hommes, le rasage concerne le plus souvent les poils du visage, et parfois le torse, le pubis, les aisselles ou encore les cheveux lorsqu'ils sont très courts. Chez les femmes, le rasage concerne plutôt les jambes, les aisselles et parfois le pubis.
Pilosité humaine
La pilosité humaine est plus ou moins abondante chez tous les humains au sein même de différentes populations, mais la présence de poils au niveau des aisselles et des organes génitaux est constante. Dans l'espèce humaine il y a de manière invariable le même nombre ainsi que le même emplacement de follicules pileux et de poils qui en résultent. Les seules différences que l'on peut constater chez l'homme proviennent de l'influence des hormones androgènes (testostérone essentiellement) sur les follicules pileux donnant lieu à des variations de type de poil.
