androgenetic alopecia follicular unit density hair density vertex hair scalp area occipital region AGA FU density

TLDR Healthy Han Chinese have lower hair density than whites and Africans, and transplanting 300 hair units can nearly restore normal hair density.

In 2017, Guan Wang and colleagues studied the hair distribution in 146 healthy Han Chinese individuals and 41 patients with androgenetic alopecia (AGA). They found that the mean follicular unit (FU) density of the healthy subjects was 74.36 ± 13.33 units/cm2 and their mean hair density was 143.33 ± 28.08 hairs/cm2, with no significant difference between males and females. The mean FU density and hair count in AGA patients were lower than those of healthy individuals. The study concluded that the FU and hair densities of healthy Han Chinese are lower than those of whites and Africans. The researchers also found that transplanting 300 FUs could achieve 90% of the normal density of vertex hair, requiring a scalp area of about 3.6 or 9 cm2 to be excised or extracted from the occipital region. These findings were intended to serve as a reference for clinical practice and future research.

research The Art of Mixing Follicular Units and Follicular Groupings in Hair Restoration Surgery

5 citations, May 2004 in “Dermatologic Surgery”

A hair restoration technique was introduced that mixes different types of hair groupings to reduce procedure time, limit damage, and potentially increase hair density, suggesting more hair can be transplanted than previously thought.
