Trichotillomania is an impulse-control disorder most commonly seen in preteen or teenaged girls. It is characterized by the repeated desire to pull out hairs, frequently eyebrows or eyelashes. Diagnosis may be elusive, as affected patients usually deny the behavior; therefore, parental counseling or psychiatric consultation may be indicated. Characteristically, multiple hairs are broken off and regrow at different lengths, a finding that guides the diagnosis (Fig 10-20).
