Monilethrix: The Use of Trichoscopy in Clinical Diagnosis

Monilethrix was a rare genetic disorder with autosomal dominant inheritance, characterized by brittle hair that did not exceed a few inches in length, primarily affecting the scalp. The most common clinical presentation included alopecia and keratosis follicularis. Diagnosis was clinical, with tricoscopy revealing moniliform changes, which involved alternating wide and narrow bands in the hair.
