title: Hair-shaft anomalies.
abstract: Variations in the structure of the hair shaft are commonly seen under the microscope and are usually of little clinical significance. Defects of the hair shaft become significant when they produce an unsightly cosmetic appearance or when they lead to the diagnosis of an underlying metabolic disorder or genetic syndrome. The article reviews hair-shaft anomalies and presents updated information and relevant clinical guidelines for diagnosing such defects.
