Follicular unit extraction (FUE), also known as follicular transfer (FT), is one of two primary methods of obtaining follicular units, naturally occurring groups of one to four hairs, for hair transplantation.[1] The other method is called strip harvesting.[1] In FUE harvesting, individual follicular units are extracted directly from the hair restoration patient's donor area, ideally one at a time. This differs from strip-harvesting because, in strip harvesting, a strip of skin is removed from the patient and then dissected into many individual follicular units. The follicular units obtained by either method are the basic building blocks of follicular unit transplantation (FUT).
