Assessment of hair density and caliber in Caucasian and Asian female subjects with female pattern hair loss by using the Folliscope

摘要

Clinical experience and past studies have suggested that Caucasian scalp hair is more dense than Asian hair, but at the same time the terminal hair fibers are thinner in average diameter." However, most of these studies were done on a single ethnic group and did not involve a direct comparison between races within the study. Few studies on hair density and thickness have utilized the Folliscope (LeadM Corp, Seoul, South Korea); most have relied on camera-based photo-trichograms and manual analysis. The Folliscope is a small, simple USB-based apparatus that is easily portable and operated by means of a computer screen as an interface. Herein we endeavor to establish some practical baseline information on hair density and diameter of Asian and Caucasian female subjects with female pattern hair loss (FPHL) by using the Folliscope, which can be used practically within minutes in the hair specialist's clinic.
