Trichotillomania is a self-induced nonscarring alopecia classified as an impulsive control disorder but with features of both obsessive-compulsive disorder and addictive disorders, that has recently received research attention. It appears to be more common than previously believed. Although most frequent in children, this repetitive hair pulling out of one's own hair can occur at any age. Psychogenic excoriations, nail-biting and other abnormal behaviors can be associated. It is important that the diagnosis is early and exact avoiding medical and psychiatric complications. Therapy for trichotillomania can be challenging.
