Abstract：
Background: Androgenetic alopecia, the most common cause of non-scarring hair loss, is a consequence of the gradual miniaturization of the hair follicles. In the majority of male androgenetic alopecia cases, a patient\'s history and clinical evaluation may be sufficient to establish the diagnosis, while for women, they should be supplemented with trichoscopy. Methods: The PubMed and Scopus databases were used to collate published studies and to analyze the most typical trichoscopic findings in patients diagnosed with androgenetic alopecia. A total of 34 articles were retrieved after exclusion. Results: The most common features identified using trichoscopy included hair diameter variability (94.07% of patients), vellus hairs (66.45%) and the peripilar sign (43.27%). Others, such as the honeycomb pattern, yellow and white dots, were less relevant. Conclusions: We concluded that hair diameter variability, vellus hairs and the peripilar sign represented valuable indicators for the diagnosis of androgenetic alopecia.
摘要：
背景：雄激素性脱发，无疤痕脱发的最常见原因，是毛囊逐渐小型化的结果。在大多数男性雄激素性脱发病例中，患者的病史和临床评估可能足以确定诊断，而对于女性来说,他们应该辅以三镜检查。方法：使用PubMed和Scopus数据库来整理已发表的研究，并分析诊断为雄激素性脱发的患者中最典型的镜检查结果。排除后共检索到34篇文章。结果：最常见的特征，使用毛镜检查包括头发直径变异性（94.07%的患者），毫毛(66.45%)和毛周征(43.27%)。Others,比如蜂窝图案，黄色和白色的圆点,不太相关。结论：我们得出结论，头发直径变异性，毫毛和外周征代表了诊断雄激素性脱发的有价值的指标。
