Body hair is a common colloquial term for the terminal hair on the human body developing during and after puberty in contrast to the head hair and the less visible vellus hair. A medical term for it is androgenic hair since its growth depends primarily on the level of androgens (male hormones) containing within the individual human organism. Due to a normally higher level of androgens men tend to have visibly more androgenic hair than women so that this type of hair can be seen as a sign for sexual dimorphism and therefore a secondary sex characteristic.
