Hair transplantation is the use of highly refined hair transplantation equipment to take healthy hairs from the back of the occipital area, and after the follicles are separated and planted to the area where the hair is missing, which has a high survival rate and is relatively safe and reliable. Secondly, hair transplantation is done under local anesthesia, involving only the skin and superficial subcutaneous tissues, without hurting the blood vessels and nerves and the brain, with little trauma and quick recovery, and the hair follicles come from oneself, so no rejection reaction and side effects will occur, and the survival rate is higher, up to 95% or more under normal circumstances. In general, the hair on the back of the occipital area is not affected by the hormones in the body and has the characteristic of not falling off for life, so the hair follicles after the hair transplantation are permanent. In the first month of hair transplantation, the transplanted hair may fall out one by one, but new hair will grow afterwards. From the aspect of medical institutions, the technique of doctors, the quality of instruments and the precision of operation, as well as the density and quality of scalp hair follicles, the internal direction of hair follicles and the degree of damage vary from person to person, all affect the results of hair transplantation. It is recommended that patients must visit a regular hospital and choose a qualified hair transplant surgeon and nurse to get the desired results.
