Follicular Unit Extraction (FUE) is a method of single follicular unit harvesting directly from the healthy donor area on the scalp (usually at the back and sides of the head), transplanting into the balding area as individual follicular units (1-3 hairs) for natural appearance. These are two main advantages of this technique: the lack of a linear scar, such as those originated with strip harvests; and a rapid recovery time, with less postoperative pain and discomfort.
This procedure is carried on under local anesthesia or intravenous anesthetic sedation by the doctor only. This method uses a specialized punch device, ranging in diameter from 0.8-1.2 mm, making a tiny circular incision in the skin around a follicular unit, separating it from the surrounding tissue and avoiding the damage to individual hair follicles. The single follicular unit is then extracted directly from the scalp, with tiny white scars buried in the hair at punched area after one week of the procedure. The follicular units are then inserted into the recipient areas where they will produce into healthy hair follicles.
The recipient sites making and the insertion of follicular unit grafts are necessarily the same in both FUT and FUE procedures. The variety remains in the presence of the donor area and in the amount and aspect of grafts acquired with each technique. The other primary season for FUE chosen by patients is the request to avoid a linear scar.
