Final answer:
The technical term for the overgrowth of hair on the body is Hypertrichosis. It is different from Hirsutism (excess hair in women in male-patterned areas), Alopecia (hair loss), and Trichotillomania (compulsive hair pulling).
Step-by-step explanation:
The technical term that refers to the overgrowth of hair on the body is Hypertrichosis. This condition can occur in any area of the body and can affect both males and females. Hypertrichosis is characterized by an abnormal amount of hair growth over the body; the etiology can be either congenital or acquired. It's distinct from Hirsutism, which is the presence of excess body hair in women in areas that are typical of male hair growth patterns, such as the face and back. Alopecia is the technical term for hair loss, and Trichotillomania is a psychological condition where there is an irresistible urge to pull out one's own hair.
