Many patients are reading about the supposed superiority of Follicular Unit Extraction (FUE) over Strip Harvesting during hair transplant surgery. Please be aware that it is very important to separate the marketing from the science. Both techniques involve cutting the of the skin. There is no such thing as a scarless technique.
Both techniques produce the same size graft. Both techniques leave scars which may, or may not, be visible to the naked eye. The difference is that FUE produces circular, small, dot scars that may also have a white appearance. Strips produce linear scars that may have hair growing through them and be very difficult to see. Short haircuts are usually possible with either technique but shaving the head will probably demonstrate scars with either technique.
