The Follicular Unit Transplantation (FUT) method is a structured surgical approach designed to harvest a high number of grafts in a single session. Understanding each step helps set realistic expectations and explains why FUT leaves a linear scar but can deliver strong density in suitable candidates. Proper planning and technique are essential to maximize graft survival and ensure a natural-looking result.
Donor Area Preparation and Local Anesthesia
The procedure begins with trimming the donor area, usually at the back of the head, to expose healthy hair follicles. Local anesthesia is then applied to ensure the patient remains comfortable and pain-free throughout the surgery. The surgeon carefully marks the donor strip area to harvest the optimal number of follicles while preserving scalp integrity.
Surgical Removal of the Donor Strip
Once the area is numb, the surgeon removes a thin strip of scalp from the donor zone. This strip contains a high concentration of healthy, DHT-resistant hair follicles that are ideal for transplantation. The extraction is done carefully to minimize trauma to surrounding tissue and reduce the risk of scarring.
Microscopic Dissection of Follicular Units
The removed strip is meticulously dissected under a microscope into individual follicular units. This step is critical to preserve follicle integrity, separate grafts according to size, and maximize graft survival. Each graft typically contains one to four hairs, depending on its natural structure, which ensures a natural hair pattern when implanted.
Creation of Recipient Incisions
Tiny incisions are made in the thinning or balding areas of the scalp. These incisions are planned based on natural hair direction, angle, and density to ensure a realistic result. Surgeons take special care to mimic the patient’s natural hairline and crown patterns, which is key for achieving a seamless appearance.
Implantation of Hair Grafts
The prepared grafts are carefully implanted into the recipient sites. Proper placement, depth, and orientation of each graft play a major role in achieving natural-looking hair growth. Surgeons may take breaks to evaluate density and spacing, ensuring uniform coverage and optimal aesthetics.
Closure of the Donor Area
After graft extraction, the donor area is closed with sutures or staples. This results in a linear scar, which is typically hidden by surrounding hair once healed. Surgeons may use trichophytic closure techniques to further minimize scar visibility and allow surrounding hair to grow through the incision.
Duration of the FUT Procedure
The entire FUT process usually takes 4 to 8 hours, depending on the number of grafts harvested and implanted, as well as the complexity of the case. Patients are often able to return home the same day, with detailed aftercare instructions provided to ensure proper healing and graft survival.
