Abstract
Male androgenetic alopecia and female androgenetic alopecia share similar trichoscopic features, including hair shaft thickness heterogeneity, yellow dots, perifollicular discoloration (the peripilar sign), an increased proportion of thin and vellus hairs, and a large number of follicular units with only one emerging hair shaft. Thin wavy hair and honeycomb hyperpigmentation often coexist as additional, nonspecific features.
