Follicular Unit Transplantation (FUT) is a procedure where hair is transplanted from the permanent zone, the area in the back and sides of the scalp are selected where hair is more resistant to balding. This is achieved using naturally-occurring groups of 1, 2, 3, or 4 hairs, called follicular units. Once the patient’s scalp is anesthetized, the doctor removes a strip of tissue from the donor area that is selected, an area within the permanent zone. Further the donor strip is cut into many individual follicular units using microscopic dissection techniques. As these follicular unit grafts are being prepared, the surgeon makes tiny holes in the scalp called recipient sites, where the grafts are placed.
The arrangement and positioning of these follicular unit grafts determines the aesthetic qualities of a hair transplant. Where the arrangement are decided on case-by-case basis for the better result.Follicular Units
Hair actually grows in tiny little groups of 1-4 hairs each. These groups are called “follicular units.”Graft Dissection
One of the most important aspects of Follicular Unit Hair Transplantation is stereo-microscopic dissection. This allows follicular units to be isolated from the donor strip without being broken up or damaged. During graft dissection, it is critical that the whole follicular unit is kept integral as this will maximize its growth. Intact follicular units will also give the most richness to the hair restoration, as they contain the full, natural complement of 1-4 hairs.Holding Solution
There are a variety of solutions that grafts can be stored in during the hair transplant procedure to maintain their viability and insure maximum growth. In our practice, we are currently using HypoThermosol.Recipient Sites
Recipient sites are the tiny slits or holes that the hair transplant surgeon makes in the patient’s scalp, where the follicular unit grafts are placed during a hair transplant procedure.Donor Area
The donor area is the area of the scalp (generally the back and sides) where hair-bearing skin is removed during a surgical hair restoration procedure. For hair transplants to be effective, the hair in this area must be permanent (i.e. not subject to the effects of Dehydrotestosterone (DHT). Minimizing the scar from the donor incision is a critical part of a successful hair transplant procedure.Graft Numbers
Determining how many follicular unit grafts will be transplanted in a hair transplant is an important aspect of planning and designing a hair transplant for the maximum possible aesthetic effect.
