The DHI Hair Transplant technique is a process that involves the extraction of hair follicles from a donor area using a micro motor, followed by their transplantation into the recipient site with a pen-like tool featuring a hollow needle. Although the Follicular Unit Extraction (FUE) method often comes to mind when discussing DHI, there are some distinct differences between the two.
The DHI technique provides the opportunity to conduct hair transplants without having to shave the head. The extracted hair follicles are transplanted within 1-2 minutes, reducing the time they spend outside the body. This method particularly favors those with non-balding areas on their scalp, as it simplifies the transplantation between hair strands. The DHI method is also beneficial for achieving a higher hair density, especially when the transplantation site isn’t large.
Comparing DHI Hair Transplant and FUE Hair Transplantation:
1) DHI employs a special Implanter (Pen) which provides precise control over the angle, depth, and direction of the implanted follicle, resulting in a completely natural hairline and appearance.
2) In the DHI method, the extracted grafts are immediately implanted into the recipient area. On the other hand, in the FUE method, extracted grafts are stored in a special solution, canals are created in the recipient area, and then the extracted grafts are implanted into these opened canals. The DHI method eliminates the need for creating canals.
3) The DHI technique avoids bleeding since the implantation is done using the special Implanter, without the need to open canals.
4) With DHI, there’s no crusting, pitting, or postulation.
5) The DHI method allows for the implantation of 80-90 grafts per cm2 without impacting the scalp’s blood supply, whereas FUE allows for 45-60 grafts per cm2. Therefore, DHI can achieve higher maximum density. For instance, if FUE can transplant 1,000 grafts in a specific receding area in the front line, DHI can transplant 2,000 grafts in the same area.
6) The maximum number of grafts that can be transplanted in a single DHI session is around 2,000, while FUE can handle up to 5,000 grafts in a session. For patients requiring more than 3,000 grafts, multiple DHI sessions will be needed. However, a Mega-DHI procedure can transplant up to 5000 grafts in a single day with two doctors.
7) Assigning angle and direction is simpler and more successful with the DHI technique, thanks to the special Implanter (Pen).
8) Shaving is not necessary for DHI, only the donor area is trimmed. In contrast, FUE requires shaving the entire scalp prior to the procedure.
9) Patients who undergo the DHI technique can resume their normal routines quicker than those who opt for FUE Hair Transplantation.
10) DHI facilitates faster recovery, and the success rate for DHI hair transplantation procedures has reached up to 95%.
