Trichotillomania (hair pulling disorder) is classified in the DSM-5 under obsessive-compulsive and related disorders. It involves recurrent pulling of one’s hair — scalp, eyebrows, and eyelashes most commonly — with repeated attempts to stop, and real distress or impairment as a result.
It is not a bad habit, not attention-seeking, and not something willpower fixes. Current research points to a blend of genetic predisposition, neurological differences, and emotional-regulation function — for many people, pulling regulates understimulation, anxiety, or perfectionistic discomfort. Onset typically falls between ages 10 and 13, and it frequently travels with anxiety, depression, or ADHD.
What works: Behavior therapy is the first-line treatment, with Habit Reversal Training (HRT) carrying the strongest evidence. Many US specialists now practice the Comprehensive Behavioral (ComB) model, which maps your individual pulling profile — sensory, cognitive, affective, motor, environmental — and tailors interventions to it. Acceptance and commitment therapy (ACT) elements are increasingly blended in. No medication is FDA-approved for trichotillomania, though some (like N-acetylcysteine) have modest research support and co-occurring conditions may warrant medication.
With BFRB-informed treatment, most people achieve meaningful, lasting reductions in pulling.
