摘　　要：毛发发育不良可分为先天性和获得性,经常累及毛干。外胚层发育不良、某些代谢性疾病、神经系统疾病、精神疾病中可以发现毛干的改变,外源性的物理、化学性刺激也会引起毛干的变化。毛干的异常表现为毛发颜色、密度、结构和长度的改变。毛干疾病的正确诊断不仅需要系统的病史和体检,光镜、扫描电镜和生化检查也很重要。Hair dysplasia could be either genetically inherited or acquired, which often involve the hair shaft. Hair shaft alterations can be found in ectodermal dysplasias, some metabolic disorders, neurological syndromes and mental disorders. They can also be induced by ectogenic physical and chemical irritations. Hair shaft abnormalities present as changes of hair color, density, structure and the length. To establish an exact diagnosis of hair shaft disorders, a systematic history taking and physical examinations are needed, the optic microscopy, scanning electron microscopy and biochemical analysis are also important.
