Hair transplantation is a more reliable procedure that is safer and provides more consistent results after surgery. Hair transplantation is to take the hair from the relatively vigorous growth area of oneself, cut the part of the tissue around the hair follicle, detach it from the original position of the scalp, and then transplant it to the position that needs the hair and has the condition of accepting the hair after a certain preparation, and let it survive and grow naturally in the new part, so as to achieve the purpose of repairing the density of the local distribution of the hair and to achieve the effect of aesthetics. The advantages of hair transplant surgery are: 1. Hairline can be designed according to the individual’s head shape, face shape, temperament and age. 2. Transplantation is done in the direction and distribution of normal hair growth. 3. The transplanted area will not leave any marks or scars. 4. The transplanted hair does not have any difference with the surrounding hair and grows with the surrounding hair. Disadvantages are that it is suitable for those who have areas with normal hair density; the transplanted hair follicles can not be fully viable and require a second surgery. Hair transplant surgery has a certain risk of infection, some patients can not grow hair normally after hair transplantation, and those who need it are recommended to visit regular medical institutions.
