Friction alopecia is a non-scarring alopecia that causes hair breakage and may cause trichorrhexis nodosa. We report a case of a 15-year-old girl with self-inflicting friction alopecia that demonstrated broken hairs and proximal trichorrhexis nodosa on dermoscopy. We review various causes of friction alopecia and clinical findings, as well as trichorrhexis nodosa.
