Follicular Unit Extraction hair transplantation or FUE, is the most advanced and sophisticated hairtransplant surgery known. In FUE follicles containing 1-4 hairs are removed individually from the donor site (usually on the sides and back of the head, chest and back) and artfully transplanted into thinning or balding areas on the head.
The individual extraction of the donor-hair leaves hardly visble scarring as opposed to the old strip-surgery method. You may want to compare FUE hair transplantation to strip-surgery.
