Picture of Trichotillomania
Trichotillomania is a compulsion in which people suffer an extreme urge to pull out their hair on the scalp, eyebrows, eyelashes, or other areas of the body. The disorder is presumed to be related to obsessive-compulsive disorder (OCD). Treatment for the disorder may include medications such as fluoxetine (Prozac) and cognitive-behavior therapy (CBT). The word is derived from Greek: tricho=hair + till(ein)=to pull out or pluck + omania.
