Trichotillomania

Trichotillomania occurs when an individual plucks out their own hair. Often the hair on the scalp is plucked to leave bald patches, but the individual may focus on the eyelashes, eyebrows, pubic hair, or any other hair-bearing region. There is much argument about whether trichotillomania is a habit like nail biting, or a more psychological problem. Either way, affected individuals are usually not aware that they are plucking their hair, and when they are made aware of it they often find it very hard to stop.
