FUT is Follicular Unit Transplantation. It is a permanent hair restoration surgical procedure where the patient's hair is transplanted in naturally occurring groups of 1 to 4 hairs, which is known as follicular units. Each unit is taken en-masse with sebaceous glands, nerves, follicular muscles and fine vellus hairs. The surgeon can then safely place thousands of grafts in a single session maximizing the cosmetic aspect of the procedure. It is the gold standard procedure done nowadays and is an advancement over older procedures of hair transplantation using larger grafts, causing extensive scarring and giving unnatural look. The result mimics natural hair growth and if done properly, it is undetectable as hair transplantation.
The donor site is usually the back of the head. The hairs are trimmed to ease the procedure of harvesting. Using precision tools, the surgeon removes whole strip from the patient's scalp. A circular incision is made around the follicle, which is dermis deep. This follicular unit is plucked out with a tweezers-like-instrument.
Trained technicians use advanced microscopes to maintain the grafts in optimal condition. Follicular units are sorted depending on the number of hair follicles contained within.
Tiny holes and slits are made to place the graft. Placement of grafts artistically is required to give a naturally aesthetic appearance. No stitches are required and the recipient site is restored to its original appearance in a few days.
Many reasons and factors in terms of cost, final results and effectiveness of the procedures have worked together to make FUT, the less preferred hair transplant procedure as compared to FUE, which is gaining widespread popularity.
