Hair shaft abnormalities are fascinating and can provide a diagnostic challenge. Current knowledge of structural changes in hair has been amplified by scanning and transmission electron microscopy (SEM and TEM). Dermatologists using the light microscope and polarization in the office can diagnose the great majority of hair shaft defects. A number of these defects are illustrated here.
毛干异常很有趣，并且可能带来诊断挑战。扫描电子显微镜和透射电子显微镜（SEM和TEM）极大地丰富了我们目前对毛发结构变化的认识。皮肤科医生在诊室使用光学显微镜和偏光显微镜就能诊断出绝大多数毛干缺陷。这里展示了其中一些缺陷。
