Types of Hair 1. Lanugo hair: It is soft, short hair covering the fetus that is shed in late gestation and during the neonatal period. 2. Vellus hair: It is soft, fine, unpigmented hair that covers apparently hairless areas of the body. 3. Terminal hair: It may be: sex hormone dependent hair as the long, coarse, pigmented hair that may grow in response to sex hormones (e.g., over the chin and abdomen of men) or may be sex hormoneindependent as eyebrows and eyelashes.
Factors affecting hair growth: • Hair growth, and thus hirsutism, is regulated by: 1. Number and concentration of hair follicles. • This varies according to racial and ethnic back-ground but not gender. • For example, Asian women generally have low concentrations of hair follicles, and hirsutism is rarely seen in these individuals.
