Hello, I am doctor Xue Zhiqiang, let me answer your question: Hair transplantation is to use special instruments to completely cut out part of the tissue around the hair follicles, remove it from the original position of the scalp, and then transplant it to the location where the hair needs to be removed. A location must be prepared and equipped to receive the hair, which is called hair transplantation.

The process of hair transplantation mainly includes: The first step: take a strip of skin flap in the occipital area, and then cut the upper and lower skin edges. After the wound heals, there will be no obvious scars, leaving only a thin scar hidden in the Among the hairs, since only a small amount of hair was removed longitudinally by a horizontal flap, there was no obvious change in the appearance of the original hair on the occiput.

Second step: Hair follicle separation: Divide the removed skin flap into several small transplant units without damaging the hair follicles, also called transplanted embryos. Each transplanted embryo contains 2-10 hair follicles. (The size of the transplanted embryo is determined based on the method of surgery). This process is very strict and requires medical staff to be extremely patient and careful. Otherwise, part of the hair follicles will be destroyed and cause losses to the patient.

The third step: Hair follicle transplantation: Make some microincisions or punch holes in the bald area to implant the transplanted embryos into the skin. This process determines the appearance after the operation. Since the number of hair follicles is limited, it is very important to artistically distribute the limited hair follicles to the top of the head to achieve the best visual effect. In particular, the hair follicle distribution is very important, otherwise even if the hair grows, it will not look good.

As long as the hair follicles are not damaged during excision and transplantation, the blood supply of the pedicles of various skin flaps is not damaged, the blood supply conditions of the donor site are good, and correct plastic surgery operations are mastered, the transplantation will generally be successful.
