"Anisotrichosis" refers to a variation in the thickness of hair follicles that is commonly seen in androgenetic alopecia. In early stages of AGA, most hairs are relatively thick in caliber but some of course are thin. Over the course of AGA more and more follicles becomes thin and very thin which extends the spectrum of follicle sizes seen.
