The diagnosis of structural abnormalities of the hair shaft is of clinical relevance, since such abnormalities may indicate underlying metabolic disorders, or may be associated with other diseases. Many of the abnormalities present themselves as alopecia and are due to greater fragility of the hair shaft. An outline of some of the most common hair shaft abnormalities is given, as shown by patients with trichorrhexis nodosa, pili torti, "uncombable hair" and pili torti et canaliculi.
毛干结构异常的诊断具有临床意义，因为此类异常可能表明潜在的代谢紊乱，或可能与其他疾病相关。许多异常表现为脱发，且是由于毛干更易折断所致。本文给出了一些最常见的毛干异常概述，如结节性脆发病、扭曲发、“难梳理发”以及扭曲发伴管腔异常患者所表现出的情况。
