Hypertrichosis syndrome

Hypertrichosis syndrome

is an abnormal amount of hair growth on the body, extensive cases of hypertrichosis have informally been called werewolf syndrome, because the appearance is similar to the mythological werewolf.

The two distinct types of hypertrichosis are :

1. Generalized hypertrichosis 

     which occurs over the entire body

2. Localized hypertrichosis 

     which is restricted to a certain area.

Hypertrichosis can be either congenital ( present at birth ) or acquired later in life. The excess growth of hair occurs in areas of the skin with the exception of androgen-dependent hair of the pubic area, face, and axillary regions.
