What term describes the overgrowth of hair on the body?

The term that describes the overgrowth of hair on the body is hypertrichosis. This condition is characterized by excessive hair growth in areas where hair is normally fine or absent. It can occur everywhere on the body or be localized to specific regions, and it differs from hirsutism, which refers specifically to male-pattern hair growth levels in women.

Albinism refers to a genetic condition characterized by a lack of melanin, leading to pale skin, hair, and eye color, but does not pertain to hair growth itself. Dermatitis is an inflammation of the skin that can result from several causes, including allergic reactions or irritants, and is not related to hair growth. Psoriasis is an autoimmune condition that leads to rapid skin cell turnover and formation of scaly, itchy patches; it also does not involve hair growth issues.

Therefore, hypertrichosis is the correct term as it specifically pertains to the quantity and extent of hair on the body.
