Follicular Unit Transplantation (FUT) is a hair restoration technique where a patient's hair is transplanted in naturally occurring groups of 1 to 4 hair, called follicular units. Follicular units also contain sebaceous (oil) glands, nerves, a small muscle, and occasional fine vellus hair. In Follicular Unit Transplantation these small units are safely transplanted in a single session, which maximizes the cosmetic impact of the procedure.

FUT is considered an advance over older hair transplantation procedures that used larger grafts and often produced a pluggy, unnatural look. In follicular unit transplant, the results will mimic the way hair grows in nature and will be undetectable.

FUT involves the removal of a strip of superficial layers of hair bearing scalp from the back and sides of the head (donor area). After the donor strip is removed, the wound edges are closed to leave a fine, hairline scar. The strip is dissected into fine follicular units with the help of microscopes and are transplanted on to the bald area (recipient area).

The main advantage of this method is to cover wider areas as it gives scope for obtaining more number of grafts in a single session. With microscopic dissection there will be lesser chance of graft wastage (transection).

In general, FUT method is the most preferred method worldwide as it yields more number of grafts which helps to cover wider bald area in a single session. In severe degree of baldness FUT method is more beneficial in terms of results and coverage and also cost and it is least tedious to the patient and to the doctor also, when compared to FUE where one can achieve less number of grafts hence less coverage in single session.
