Human hair grows on the underarms, the genitals, legs, arms, and on the top of the head in adults of both genders. Hair will usually grow on the face of most adult males, and on the chest and back of many adult males. In human children of both genders, long hair grows only on the top of the head. Although it might look like humans have fewer hairs than most primates, they actually do not. The average human has more hair "follicles", where hair grows from, than most chimpanzees have. Human hair can be black, brown, red or blond. When humans get older hair can turn grey or white.
