This Norwegian study is testing a type of group therapy called ACT-enhanced habit reversal training to help people with trichotillomania—a condition where people repeatedly pull out their hair. The therapy combines acceptance and commitment therapy (ACT) with practical habit-reversal techniques taught by trained therapists. Over 150 people ages 16 and older are being invited to participate across three treatment sites in Norway.
Trichotillomania can cause real distress and shame, but there aren't many proven group treatment options available. This study aims to show whether this specific type of group therapy—which combines learning to accept urges while developing new behaviors—actually works and helps people stay better even a year after treatment ends.

You would attend 10 three-hour group therapy sessions held once per week for 10 consecutive weeks, where you'll learn techniques to manage hair pulling alongside other participants. After treatment ends, you'll come back for 2–3 booster sessions during your first year. Throughout the study, therapists and researchers will measure your progress using questionnaires and brief clinical interviews at the start, at the end of the 10 weeks, and again one year later.
