There are two types of hair transplants: follicular unit transplantation (FUT) and follicular unit extraction (FUE).
A follicular unit transplant (also called strip surgery) is much more invasive than modern hair transplants. In FUT, a long thin strip of scalp is cut out, typically from lower down on the back of the head. The hair follicles are divided into single units under a microscope. The scalp is then sewn back together where the strip was removed. Because the extraction phase is much quicker, FUT is a cheaper hair replacement method than the alternatives. However, it leaves a significant scar that can be seen under short hair. If you’re prone to keloid scarring, the scar can be very noticeable.
“F.U.E.” or “Follicular-Unit Extraction” is an advanced, “minimally-invasive” hair transplant method which allows for the harvesting of individual follicles from the back of the head (donor area) without a scalpel or stitches, and therefore leaves no linear scar.
The grafts units are harvested randomly from the back and the sides of the scalp. The hair restoration surgeon makes a small circular incision around the hairs and then extracts them from the scalp. When enough follicular units have been harvested, they are then implanted individually in the target areas.
