Hair replacement surgery frequently requires multiple grafts of hair being implanted during multiple sessions, generally spacing each session at least four months apart to allow for adequate healing. The surgeon will explain which type of anesthesia is indicated. Facial plastic surgeons usually decide on a local or twilight anesthesia for grafting, but many surgeons choose general anesthesia for grafting, but many surgeons choose general anesthesia for the more involved surgical procedures for replacing hair. The surgical facility to be used will also be determined by the extent of the procedure. It is not essential to be bald or nearly bald before undertaking hair transplantation.
Age also is no contraindication for hair transplantation.
The younger the person, though, the more conservative the approach must be for transplantation, because the permanent donor site may not yet be established. Ideally, the patient should have dense growing hair in the donor sites to sufficiently fill any present or future areas of baldness. The color of the hair in contrast to the skin color will be discussed with you by your surgeon. The texture of your hair, coarse or fine, will also determine the final result in hair transplantation. However, the patients most satisfied with hair transplantation are those who will accept the estimate of improvement as given by the surgeon.
