They are thin to the point that they can barely be seen in most cases. Skilled doctors have ways of making the scars practically disappear. First of all, the surgeon must be very skilled in choosing the site of the path where he harvests the donor tissue for the hair transplant. Its width should be no more than one centimeter in most instances. However, it does not affect the back and sides of their hair in most cases. These areas have healthy hair follicles and make excellent donor sites for hair transplant surgery. These are called stable sites because they remain unchanged over time rather than shrinking like the hair follicles affected by DHT do. Planning for the procedure is necessary before you even make the final decision to have it done. Once that step is completed, you will be ready to start the preparations for your surgery. Before you are approved for a hair transplant procedure, the doctor will have to sign off on you. You must be deemed appropriate for the surgery. If you have a high number of hair follicles per square centimeter than most people, more grafts can be done, so your hair will look fuller. 3. Your scalp laxity will also affect the fullness of your resulting hair transplant site. This refers to the flexibility of your scalp. How loose your scalp is helps to decide how many grafts can be done just as hair density does. Once the follicular units for the hair transplant are dissected out of the donor tissue, technicians set them aside in a saline solution. The temperature must be ideal or the small grafts will not survive the procedure. This is done very carefully in order to ensure a good result. The surgeon will make tiny incisions into the scalp where the hair transplant grafts are to go. It is necessary to clean gently but thoroughly. At first, you may find yourself rinsing your hair many times a day. Just be sure that you do not bother the hair transplant site by scratching or rubbing it. Your hair transplant doctor will want you to come in for a check of your transplants about a week after your surgery.
