Follicular Unit Extraction (FUE) is a technique of extracting, or harvesting, individual follicle units by punching around the follicles unit. In an FUE procedure, the surgeon will make a small, circular punch in the skin around a follicular unit, separating it from the surrounding tissue. The unit is then extracted (pulled) directly from the scalp, leaving a small punch defect of point 8/9 millimeter which heals in few days leaving tiny white scars buried in the hair in the back and sides of the scalp. This process of follicular separation is repeated until the surgeon has harvested sufficient follicular units for the planned hair restoration. This process can last two or more hours and, in longer sessions, may be accomplished over two stages. This method of donor harvesting is what differentiates the FUE procedure from a traditional Follicular Unit Transplant (FUT), where the donors hair is removed from the scalp in one thin, long strip and then subsequently dissected into individual follicular units using a stereo-microscope.
