Today, hair transplant physicians can utilize various techniques to extract and transplant large numbers of hair follicles (follicular units). There are there basic methods to grow hair currently used. Follicular Unit Transplantation (FUT), Follicular unit extraction (FUE) and Direct Hair Implant (DHI) method.
A hair transplant involves taking healthy hair follicles (from an area resistant to balding) and implanting them into the treatment area. Both the extraction phase and implantation phase are equally important. The key difference between FUT and FUE techniques are how the donor hair follicles are extracted. We explain below:
. FUT (Follicular Unit Transplant) is one traditional technique where a long thin strip of scalp is removed, typically from lower down on the back of the head. The hair follicles are then divided into single units under a microscope. The area from where the strip is taken is sutured leaving a linear scar on the scalp that can be seen under short hair.
In cases of advanced hair loss, FUT is preferred because it allows for the greatest number of grafts to be transplanted in a single session and it is a cheaper form of hair transplant as the extraction phase is quicker than alternative techniques.
During FUT Procedure
How does the procedure work?
The FUT or strip method involves the following steps:
. Follicular Unit Extraction (FUE), The FUE hair transplant procedure is a technique where the required amount of hair groupings of 1, 2, 3 or 4 hairs called follicular unit grafts are extracted from the patient’s bald resistant donor areas (usually the sides and back of the head) and are then transplanted in the balding or thinning areas of the patient’s scalp.
Instead of conducting the conventional strip excision method, each of the individual follicular unit grafts are extracted from the patient’s donor area by utilizing micro-motors containing special leads. The tiny dots that occur as a result of the procedure are so small that they even do not require any stitches; and owing to this, unless viewed under a magnifier the remaining small scars are hardly noticeable.

How does the procedure work?
FUE transplants are relatively unobtrusive and are performed under local anaesthetic, so as to reduce complications or the need for long stays. The process is reasonably simple and quick, and undergoing FUE in the vast majority of cases have no complications for patients, most of whom can return to work the following day.
FUE hair transplants are all carried out under a microscope by experienced professionals to ensure absolute precision and to help create as natural a restored hairline as possible.
FUE is a newer technique and unlike other hair transplant procedures, FUE works on an individual hair basis. Each hair is extracted as a whole unit, complete with the necessary glands and then transplanted to the new area. Although less invasive, the procedure is very intricate and this can lead to an FUE procedure taking slightly longer than the FUT method. By taking more time, the healing period is reduced and the levels of success are greater. Whilst no procedure is scar free, the scarring of FUE is limited to small dots which become invisible after a short amount of hair growth.
Using FUE, we expose the follicles to as little in the way of damage as possible, and this gives each transplanted hair the best chance of survival. Because the follicles have been taken from an area of hair unaffected by DHT – the hormone causing male pattern baldness – the new hairs are unaffected and will not be subject to the same patterns of loss.

The Stages of FUE procedure are as follows:
. Collection: The grafts are removed one by one from the scalp by the tool “micro motor” which has a hole and a sharp point. With this method, depending on the patient’s graft size, the points changing between 0.7-1.25 of diameters are used. The grafts, whose sides are split from the hairy skin, are collected by the technicians individually.
. Canal Stage: At this stage micro sized tools called “handle”, which are appropriate for the grafts’ height and thickness and exhibit a little sharp surface, are being used. Once the recipient area is receptive to no pain or discomfort, the micro-lateral incisions will be made with specific interest in angle, depth, orientation and density.
. Plantation: The grafts that were collected in the collection stage are planted in the holes which were opened in the canal stage. The plantation stage is also very important. Hairs are placed in the canals that were appropriately opened for the collected grafts, one by one with highest care. In this stage, like our natural hair, it is of utmost importance that the grafts, which contain one strand of hair, are planted in the front.
. Direct Hair Implant (DHI), In DHI hair transplant method the collected hair is directly planted in the area. The tools called “DHI pens” are used in this method which does not require to open canals beforehand. After the hair is put inside these pens, they are implanted directly in the area. By this, because the canals are opened exactly the size of the graft, there are less transplantation marks and bleeding.

During DHI Procedure
DHI hair transplant Stages
The Stages of DHI procedure are as follows:
. Collection: In this stage, with a specific tool called “micro motor”, the hairs who are smaller than 1 diameter are removed from the scalp and collected. There will not be any scars or cuts and the collected hairs are immediately suitable for transplantation.
. Arrangement: The hairs are carefully put in the pens which contain suitable canals for the height of the hair strand.
. Plantation: The hairs inside the pens are stuck in directly in the hairless area, thus the canals are opened and the hairs are planted at the same time. The hair is transferred easily, suitably for the angle and the depth in the area. They will stay forever and never be lost post transplantation.
What is the difference between DHI and FUE?
The main difference between FUE and DHI is in the way grafts are implanted into the recipient area.
While during FUE the surgeon manually implants the extracted grafts, with DHI a specific implanter tool (also known as Choi Implanter Pen) is used. Moreover, FUE requires canal opening prior to implantation. DHI allows the implantation to happen right after extraction, without the need to create holes or slits for the grafts to be implanted.
