The excessive hair growth on the body is called hypertrichosis. Hypertrichosis is a condition that is characterized by excessive hair growth over the body. The two distinct types of hypertrichosis are generalized hypertrichosis, which occurs over the entire body, and localized hypertrichosis, which is restricted to a certain area. Hypertrichosis can be either congenital (present at birth) or acquired later in life. The condition is always found in males because the trait is Y-linked and son always gets it from father. Hypertrichosis disease is also known as “Werewolf Syndrome”.The presence of coarse pigmented hair on the face and chest in a female is called hirsutism. It is due to hyperandrogenism.
