Body hair varies among women, though the hair on a woman's chest, abdomen, back, upper lip and chin tends to be fine and light in color. Hirsutism may make hairs in those regions thicker or darker-colored, according to the U.S. National Library of Medicine.
Women with hirsutism produce more male hormones than usual, generally due to genetics, according to Mayo Clinic. In addition to hirsutism, which is harmless, excessive body hair in women may also result from tumors or other health problems, explains the U.S. National Library of Medicine. When women's fashion became more revealing in the early 1900s, American women began to remove the hair on their legs, armpits and other specific areas of the body, notes The Guardian.
