Hair loss. Head of a 22 year old woman showing an area of hair loss due to alopecia areata. The causes of this condition are unknown, but it is painless and the hair often regrows after a few months. There is no specific treatment for the condition, although a wig may be used to cover an extensive bald area, or a hair transplant can be used in the case of a chronic attack.
