In FUE hair transplant we harvest the grafts from the back and sides of the head, which is called the donor area, to transfer to the needed areas, the front, top or crown area. The total number of grafts on the head does not change after the hair transplant. In other words, it is a simply a transfer, the harvested are taken from the back and brought to the front. The grafts that are harvested do not grow back, thus, we do not have an infinite number of grafts at the back. Therefore, it is very important to harvest carefully, without traumatizing the donor area so that the back continues to look good after the hair transplant despite the harvesting. When we receive photos, we want to see mainly three things; how strong the donor area is, how wide the recipient area is and how thick the grafts are. If the donor area is strong and the recipient area is not too wide, then there is a good match. If it is the reverse, the patient might not be eligible for hair transplant or might need two sessions (with at least 6-8 months in between).
