Follicular unit extraction (FUE), also known as follicular transfer (FT), is one of two primary methods of obtaining hair follicles, naturally occurring groups of one to four hairs, for hair transplantation. The other method is called strip harvesting.
The specialised punch used in FUE allows the surgeon to remove hair from the skin without causing damage. The hair transplantation is non-evasive and therefore the scalp heals faster. A patient can often show no visible signs a couple of days days after surgery.
The small hole left behind after the follicle is extracted takes a few days to heal and as it does so the small wound contracts which makes the remaining scar much smaller and less noticeable. The patient often has hundreds of small round white scars which are typically invisible to the human eye after his or her hair has grown out.
