Dr. Zhi-Qi Hu, MD, chariman of plastic surgery of Nanfang Hospital. He have engaged in plastic and cosmetic
surgery for more than 20 years. His research interest is advanced basic and clinical facial paralysis, basic and
clinical study of hair transplantation. He is experienced in clinical curing for AGA, scar after trauma, and congenital
facial deformity. Now he is devoting himself to curing alopecia, including the medicine cure, and the surgical
operation - follicle unit extraction (FUE). At present, his research of hair transplantation gets ahead in China and the
research of hair follicle regeneration is in the domestic first-class and international advanced level.

ABSTRACT
Article history: Aim: To explore the characteristics of normal hair distribution in Han Chinese. Methods:
Received: 6 Aug 2017 A total of 146 healthy Han Chinese and 41 patients with androgenetic alopecia (AGA) were
Accepted: 8 Sep 2017 selected as research subjects. Digital photographs of the vertex, temporal, and occipital
Published: 28 Sep 2017 regions were taken after their hair was trimmed. An image analysis software was used to
compute the number of follicular units (FUs) and hairs. Results: The mean FU density of

distribution and their mean hair count was 148.12 ± 6.98 hairs/cm . Both were lower than those of healthy

Han Chinese, and the differences were statistically significant (P < 0.001). Two-hair FUs
(52.62%) were the predominant type found in Han Chinese. Conclusion: The FU and hair
densities of healthy Han Chinese are lower than those of whites and Africans. The study
provides hair transplantation surgeons with information on hair distribution in Han Chinese.
It also provides a quantitative basis for the area of donor site and transplantation density
necessary for hair transplantation surgeries. The research findings provide some theoretical
data for the hair distribution characteristics of Han Chinese. These data can contribute to the
preoperative assessment, surgery planning, and postoperative outcome evaluation by hair
transplantation surgeons.
