Young Brunette Girl With Tan Lines And Pubic Hair Landing Strip Undresses Her Camisole And Panties Near The Old Green House

Although fine vellus hair is present in the area in childhood, pubic hair is considered to be the heavier, longer and coarser hair that develops during puberty as an effect of rising levels of androgens. Pubic hair is therefore part of the androgenic hair (or body hair) and is a secondary sex characteristic.
Development
The development of pubic hair can be assessed using the Tanner scale. Before the onset of puberty, the genital area of both boys and girls has very fine vellus hair, referred to as Tanner stage 1 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 and rougher, 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.
