FUE or follicular unit excision is one of the methods for hair follicle harvesting in hair transplantation. FUE involves harvesting hairs from the donor area, under local anesthesia which is most commonly the scalp but occasionally beard, chest and other parts of the body, using a circular punch less than a mm, mounted on a manual handle or a motorized hand device or more recently a robotic device. First hair transplant was done by Dr Shoji Okuda in 1937. The term "follicular unit extraction" was coined by William Rassman in 2002. The modern era of FUE begins with the work of several surgeons Woods, Rassman, Cole, Harris and Rose. FUE has gone through various stages of development from manual to motorized and blunt to sharp, serrated trumpet and flared punches. Now the use of the robot in FUE with extraction and incision making is also in use. In 2017 nomenclature committee headed by Parsa Mohebi of ISHRS, recommended the term "FOLLICULAR UNIT EXCISION" is most appropriate as it explains the two steps of the process: incision and extraction and incision is done by a physician. FUE is a surgeon based time-consuming procedure with the long learning curve. Use of motorized device and sharp punches has certainly helped to increase speed in an experienced hand. FUE method of hair transplant is the most demanding procedure. If done properly it is a safe procedure. with the experience, use of better quality of instrument the disadvantages of FUE like transection can be reduced. The above informations were collected from various papers published in authentic journals and textbooks.
