Today, hair transplant doctors can use various techniques to remove and transplant large numbers of hair follicles (follicular units). There are basic methods for growing hair that are still used.
Follicular Unit Transplantation (FUT),
Follicular unit extraction (FUE) and
Direct Hair Transplantation (DHI) method.
Hair transplant involves taking healthy hair follicles (from a hairless area) and placing them in the treatment area. Both the extraction step and the implantation step are equally important. The main difference between FUT and FUE techniques is how the donor hair follicles are removed.
FUT (Follicular Unit Transplantation) is a traditional technique in which a long thin strip of scalp is removed from the bottom down, typically on the back of the head. The hair follicles are then divided into single units under the microscope. It is sewn to the area where the tape was taken, leaving a linear scar on the scalp so that it can be seen under the short hair.
In cases of advanced hair loss, FUT is preferred because it allows the most grafts to be transplanted in a single session, and it is a cheaper form of hair transplantation because the extraction phase is faster than alternative techniques.
The FUT or lane method includes the following steps:
Initially, the doctor numbs the scalp.
A strip of your hair tissue is removed from the area called the donor area, or the area where the hair on your head is more resistant to balding, that is, from the back and sides.
The doctor then stitches the area where the strip of hair tissue was removed. This leaves a thin scar that can be easily covered with your remaining hair.
The donor strip is cut into separate follicular units (groups of approximately 1-4 hair follicles) by precise microscopic dissection.
The doctor then makes small holes in your scalp where the hair loss occurs and places the follicular graft units.
A disinfecting solution is gently applied to your scalp.
A bandage is put on your donor area.
Follicular Unit Extraction (FUE), hair transplantation, is a technique in which the required amount of hair groups consisting of 1, 2, 3 or 4 hairs, called follicular unit grafts, are taken from the patient’s resistant donor areas, usually from the side and back areas. And then it is transplanted to the balding or thinned areas of the patient’s scalp. Instead of the traditional strip excision method, each follicular unit graft is removed from the patient’s donor area using micro motors with special tips. The tiny dots that result from the procedure are so small that they don’t even require stitches. And because of this, the tiny marks left are hardly noticeable unless viewed under a magnifying glass.
FUE transplants are relatively unobtrusive and are performed under local anesthesia to reduce complications or the need for prolonged stays. The process is fairly simple and quick, and in the vast majority of cases, undergoing FUE has no complications for patients, most of whom can return to work the next day.
FUE hair transplantation is performed under a microscope by experienced professionals to ensure absolute precision and help create as natural a hairline as possible.
FUE is a newer technique and unlike other hair transplant procedures, FUE works on the basis of individual hair. Each hair is taken as a complete unit with the necessary glands and then transplanted into the new area. Although less invasive, the procedure is very complex and this can cause an FUE procedure to take slightly longer than the FUT method. By taking more time, recovery time is shortened and success levels increase. While no procedure leaves scars, the scars of FUE are limited to small spots that become invisible after a short hair growth.
In Direct Hair Implant (DHI), the hair collected in the hair transplantation method is transplanted directly to the area. In this method, which does not require grooving beforehand, tools called “DHI pencils” are used. After the hair is placed in these pens, they are planted directly on the area. Thus, since the channels are opened exactly at the size of the graft, there will be less scarring and bleeding.
