Trichotillomania: Clinical Aspects and Treatment Strategies

Trichotillomania is a disorder of compulsive hair pulling that often results in alopecia. The clinical features include the pulling of hair from the scalp, eyebrows, and eyelashes, sometimes symmetrically; pubic and other bodily hair may also be plucked. The disorder is present in 0.6% of college students. The majority of sufferers who seek treatment are female, with usual age of onset between 11 and 16 years. Trichotillomania can occur in a wide variety of psychiatric disorders, and patients with the condition may be more likely to have a lifetime diagnosis of depression or an anxiety, eating, or substance abuse disorder. Although empirically derived treatment guidelines are still lacking, the current literature suggests that behavior therapy and pharmacotherapy are the most efficacious treatments for adult trichotillomania. Controlled trials with pharmacotherapy (clomipramine) have shown significant reductions in hair pulling over the short term. Controlled investigations of behavior therapy have not been conducted, but several treatment series suggest efficacy. At least three reports also suggest that behavior therapy and pharmacotherapy bring some improvement in childhood trichotillomania, although this has not been empirically studied. A case illustrating the combination of behavior therapy techniques and pharmacotherapy in the treatment of trichotillomania is presented.
