FUE is a method in which hair follicles are harvested individually from the back of the head and transplanted to the desired area. The transplanted area will initially develop scabs and redness, and the transplanted hair will fall out once before regrowing over the course of several months. The final results appear gradually over a period ranging from several months to about one year, and there is significant individual variation.
