Corkscrew Hairs in Trichoscopy of Trichotillomania

A woman in her twenties presented with progressive hair thinning, and after clinical, dermoscopic, and histopathological evaluations, she was diagnosed with trichotillomania (TTM), a psychodermatological disorder characterized by recurrent hair-pulling. The examination revealed features such as irregularly broken hairs, corkscrew-like hairs, and trichoptilosis. TTM is often associated with anxiety or depression and is classified under obsessive-compulsive disorders. The patient was advised to undergo habit reversal therapy and iron supplementation. This case highlights the importance of dermoscopy in distinguishing TTM from other forms of alopecia and reports the novel observation of corkscrew hairs in TTM, which are typically associated with tinea capitis.
