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 scalp from where the strip was removed is then sewn back together. It is a cheaper form of hair transplant as the extraction phase is quicker than alternative techniques, however it leaves a significant scar that can be seen under short hair and if you are prone to keloid scarring, it can cause a very noticeable scar where the strip was removed.
FUE (Follicular Unit Extraction)
is another traditional technique where a punch is used to make a small circular cut in the skin around a hair follicle or group of follicles, removing them from the scalp, leaving a
small open hole.
The process is repeated until the surgeon has enough follicles to cover the treatment area. The holes heal to tiny white scars throughout the donor area and can be undetectable depending on the skill of the surgeon. These scars heal quicker and are less visible than with FUT
DHI extraction could be referred to as a micro-FUE and only punches with diameter of 1mm or less are used to extract hairs one by one from the donor area. This minimally invasive DHI extraction is always done 100% by a certified surgeon ensuring consistency and high quality. This minimally invasive DHI-extraction completely prevents scrarring.
With both the FUT and FUE options, follicles are implanted the same way, by creating reception holes in the treatment area and placing the hair follicles into the holes with forceps, allowing little control over the angle, direction and depth. Implantation is normally done by technicians, not by a surgeon. With these traditional techniques, the focus is on how many follicles are extracted and little or no emphasis on follicle survival rate after implantation, which is crucial.
With the DHI Direct Technique each follicle is separately placed directly to the affected area with the DHI implanter, the specially designed tool for hair transplant and hair loss treatment. With DHI implanter, doctors can control the depth, the direction and the angle, each graft is placed. Thus, the new hair does not fall, the grafts live longer and the final look is 100% natural. Direct implantation of hair follicles with the DHI implanter provides a natural look, without visible scars on the affected area.
