TLDR Trichoscopy is useful for diagnosing hair-pulling disorder.
In 2020, two studies were conducted on trichotillomania, a hair-pulling disorder. The first study involved 30 patients and found that the most common trichoscopic features were broken hairs (100% of patients), black dots (93.3%), and flame hairs (86.7%). Less common findings included V-sign (60%), tulip hairs (53.3%), and hair powder (46.7%). The second study involved 20 patients and found that broken hairs were present in all patients (100%), followed by short vellus hairs (90%), black dots (85%), trichoptilosis (75%), V hair (70%), hair powder (65%), among others. The study introduced two novel findings: branched hair and concentric hair. Both studies concluded that trichoscopy can be a useful tool in diagnosing trichotillomania.
