TLDR The document concludes that signs of male and female pattern baldness include uneven hair thickness, yellow spots, skin discoloration around hair follicles, more thin and soft hairs, and many hair follicles with just one hair.

The document from 2011 discussed the trichoscopic features of male and female androgenetic alopecia. These features included 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. Additional, nonspecific features often coexisting were thin wavy hair and honeycomb hyperpigmentation.
