Follicular Unit Transplantation (FUT) is a surgical approach for hair transplantation that involves removing a strip of skin from the donor area, typically the back and sides of the scalp, underneath local anesthesia. The strip is dissected into individual follicular units by trained surgical technicians using specialized instruments and a microscope.
The FUT approach requires the use of a multi-blade knife or a motorized punch tool to harvest donor hair follicles. The tool removes a strip of skin from the donor area, which is then dissected into individual follicular units, usually consisting of one to four hairs each. The donor area is then sutured closed, creating a fine scar which, with correct surgical technique, becomes either invisible or disguised by the remaining hair.
The FUT hair transplant approach is more invasive than Follicular Unit Extraction (FUE). However, it can provide more significant numbers of grafts in one session than FUE, which makes it a good choice for patients with extensive hair loss. FUT also typically requires less extensive shaving or trimming of hair on the scalp than FUE, making it a more discreet option for patients who are concerned about the social consequences of having noticeable postoperative scarring or shaved areas on their head. FUT procedures also tend to be less expensive than FUE, due to the lower level of manual intervention required by surgical technicians.
