Pubic hair and its characteristics

Pubic hair

Pubic hair is hair which grows in the pubic region i.e in the frontal genital area, the crotch, and sometimes at the top of the inside of the legs.

Although fine vellus hair is present in the pubic region in childhood, the term pubic hair is generally restricted to the heavier, longer hair that develops with puberty as an effect of rising levels of androgens. Pubic hair is therefore part of the androgenic hair.

pubic hair development

Before puberty, the genital area of both girls and boys has very fine vellus hair, referred to as Tanner hair. As puberty begins, the body produces rising levels of the sex hormones known as androgens, and in response the skin of the genital area begins to produce thicker, often curlier, hair with a faster growth rate. The onset of pubic hair development is termed pubarche. The change for each hair follicle is relatively abrupt, but the extent of skin which grows androgenic hair gradually increases over several years.

There is very little difference in the capacity of male and female bodies to grow hair in response to androgens. The obvious sex-dimorphic difference in hair distribution in men and women is primarily a result of differences in the levels of androgen reached as maturity occurs.


Pubic hair can vary in color considerably from the hair of the scalp. It is different from leg hair. In most people it is darker, although it can also be lighter. Hair texture varies from tightly curled to entirely straight. Pubic hair patterns can also vary by race and ethnicity.

* collection of secreted pheromones

* warmth
