When you contact a hair restoration surgeon, ask to see a portfolio of patients' photos before and after hair transplant surgery. You should be suspicious if you are shown less than a dozen or so sets of pictures. This may mean the doctor does not have much experience to brag about. The pictures should be of good quality so that you can really see what kind of job was done. It is just a fact of life. However, if the surgeries are handled in the proper manner, the scars are barely noticeable. 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. You should figure that the average number of hair transplant grafts needed to cover a balding area is 25% of the original hair that was there. You can move up or down from this figure according to your other factors such as thickness, curliness, or color. Then, you can use this number to figure up the grafts needed. How Are Follicular Units Used in Hair Transplant Surgery? Certain doctors have been aware of follicular units for a long time now, but the knowledge only recently made its way into hair transplant methods. Now these ideas are being used in hair restoration every day. To understand how follicular units have affected hair transplant surgery practices, it is necessary to first understand what a follicular unit is. You can start out by getting some kind of hat. It does not matter what kind of hat it is, as long as it is fairly loose-fitting so that it does not rub on your new hair transplant grafts. You should not have to put up with this for long. After a couple of weeks, you can replace the cap with sunscreen. Do not get involved with a doctor who does not listen. A good doctor knows how important the hair transplant is to you. He will listen to your questions about hair transplant and provide intelligent answers. He will also try to find out what your goals are to see if they are realistic. 6. Keep it realistic.
