TLDR Southern Chinese women with female pattern hair loss have less, thinner hair and smaller hair follicles.

This study used phototrichogram to investigate the characteristics of hair in female pattern hair loss (FPHL) patients and healthy females in Southern China. The results showed that FPHL patients had reduced hair density, hair diameter, and terminal/vellus hair ratio, which correlated with the severity of Ludwig staging. Midscalp was the most affected area in FPHL, but occipital and temporal sites were also involved. The study concluded that reduced hair density and hair diameter, and miniaturization of hair follicles are the characteristics of FPHL in Southern Chinese women. Age-associated changes might have an influence on the hair condition.
