Hello! Hair transplantation, also known as "autologous hair transplantation", takes hair follicles in the posterior occipital region of human body as hair sources, extracts them with special instruments, and then separates them into single or multiple hair follicle units. After extremely careful surgery, the hair follicle is transplanted to the site where it needs to be transplanted, and then it can survive in the new site. The pillow hair follicle extracted by hair transplantation is not affected by DHT, and the newly grown hair will not fall off again after being implanted in the alopecia area, thus repairing the distribution density of local hair and achieving beautiful results. Therefore, you can rest assured that your hair will not fall off after being planted by Dr. Yili in Guangzhou.
