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.<\/jats:p>","DOI":"10.3390\/life16091434","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T12:27:46Z","timestamp":1787920066000},"page":"1434","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hormonal Medication Effects on Trichotillomania and Skin Picking Disorder"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9556-3935","authenticated-orcid":false,"given":"Sophia","family":"Boutouis","sequence":"first","affiliation":[{"name":"Department of Psychiatry & Behavioral Neuroscience, Pritzker School of Medicine, University of Chicago, Chicago, IL 60637, USA"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Megha","family":"Neelapu","sequence":"additional","affiliation":[{"name":"Department of Psychiatry & Behavioral Neuroscience, Pritzker School of Medicine, University of Chicago, Chicago, IL 60637, USA"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"given":"Laurie","family":"Avila","sequence":"additional","affiliation":[{"name":"Department of Psychiatry & Behavioral Neuroscience, Pritzker School of Medicine, University of Chicago, Chicago, IL 60637, USA"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7784-7021","authenticated-orcid":false,"given":"Jon E.","family":"Grant","sequence":"additional","affiliation":[{"name":"Department of Psychiatry & Behavioral Neuroscience, Pritzker School of Medicine, University of Chicago, Chicago, IL 60637, USA"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2013).
