Hormonal Medication Effects on Trichotillomania and Skin Picking Disorder

Background: Trichotillomania (hair pulling disorder) and skin picking disorder often begin around puberty, suggesting the potential role of hormones in the etiology and maintenance of these conditions. However, little research has explored whether usage of hormonal medications, including birth control, affects symptoms in people with these disorders. Methods: Two hundred and ten women with self-reported trichotillomania and/or skin picking disorder were recruited from the community if they had previously taken a hormonal medication in their lifetime. Data were collected on the perceived relationship between hormonal medication use and severity of hair pulling or skin picking. Results: While some women reported positive and/or negative effects of hormonal medications on their hair pulling (18.0%) or skin picking (17.8%), most women (approximately 82.0%) reported no change in symptoms while taking these medications. Conclusions: Sex hormones may still influence the precipitation of trichotillomania and skin picking disorder; however, they appear to have continued effects on hair pulling and skin picking in adulthood for only a subset of those with these conditions.
