Diffuse androgenetic alopecia (female pattern hair loss), telogen effluvium, and diffuse alopecia areata may have similar clinical manifestations. Subtle details on physical examination and dermoscopy of the scalp may help to identify those disorders. The authors present a practical discussion on how to approach the patient with diffuse alopecia, considering clinical history, physical examination, and dermoscopic findings. If the diagnosis remains unclear after a careful analysis of the clinical signs, a scalp biopsy may help to distinguish between the three diseases. In this first part of our study, an objective review of female androgenetic alopecia is presented and the most important histological changes are discussed.
弥漫性雄激素性脱发（女性型脱发）、休止期脱发和斑秃可能有相似的临床表现。头皮体格检查和皮肤镜检查的细微细节可能有助于鉴别这些疾病。作者结合临床病史、体格检查和皮肤镜检查结果，对如何诊治弥漫性脱发患者进行了实用的讨论。如果在仔细分析临床体征后诊断仍不明确，头皮活检可能有助于区分这三种疾病。在本研究的第一部分，我们对女性雄激素性脱发进行了客观综述，并讨论了最重要的组织学变化。
