Trichotillomania (TTM), or recurrent hair pulling, is classified by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; American Psychiatric Association, 2000) as an impulse-control disorder that is characterized by (1) recurrent pulling out of one's hair, resulting in noticeable hair loss; (2) an increasing sense of tension immediately before pulling out the hair or when attempting to resist the behavior; (3) pleasure, gratification, or relief when pulling out the hair; (4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatological condition); and (5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning (p. 677).
