In both of these surgical techniques, the end result is exactly the same – transplantation of individual hair follicles. The primary difference between these two hair restoration methods is the follicle harvesting technique. Follicular Unit Excision or Extraction (FUE) harvests each hair follicle individually, usually with the assistance of a mechanized or robotic tool. Follicular unit transplantation (FUT) involves removal of a thin strip of skin containing hair follicles from the back of the head and harvesting each follicle individually using microscopic excision.
