DHI Hair Transplant

WHAT IS DHI HAIR TRANSPLANT?

DHI hair transplant method is the most modern method developed and named after direct transplantation without opening a channel to the transplantation area, the hair to be transplanted is placed under the skin with the help of a pen called Choi Pen.

DHI stands for “Direct Hair Implant” / Direct Hair Implantation. The DHI transplantation is performed with a pen-like medical device (CHOI Implanter Pen), so this method is also called pen technique/hair transplantation with the pen.

DIFFERENCE BETWEEN DHI AND FUE HAIR TRANSPLANTATION

The main differences between the follicular unit transplantation (FUE) method and the direct hair transplantation (DHI) method are quite important. In the FUE hair transplantation method, channels are opened in the area to be transplanted and then hair follicles or grafts taken from the donor area are placed in these channels.

In the DHI hair transplantation method, hair follicles or grafts taken from the donor area are placed directly into the area to be transplanted using a special pen. Therefore, in the DHI method, no canal is opened in the area to be transplanted.

Thanks to DHI hair transplantation, the grafts taken from the donor area do not have to wait outside for a long time. This makes the grafts healthier and more durable. Therefore, it is possible to achieve a more natural look in hair transplantation with the DHI method.

How is DHI hair transplant performed?

Hair transplantation with the FUE method basically takes place in 3 steps: The first step is to collect the grafts, the second step is to open the channels in the area to be transplanted and the last step is to transplant the collected grafts/hair follicles into the opened channels.

The first step in transplantation with the DHI method is the collection of grafts. For this, as in FUE, hair follicles/grafts are collected from the donor area. In the second stage, thanks to the special medical device used, the collected grafts are transferred directly to the area to be transplanted without the need to open a channel beforehand. The canal is opened in a few seconds with the DHI pen and the graft is placed into the canal. Differently from the FUE method, canal opening, and root placement are performed in one step.

PAINLESS ANESTHESIA (SEDATION) METHOD

Information is provided about the DHI method used in hair transplantation. The main points are as follows:

  • Local anesthesia is applied at the beginning of the operation. Optionally, it can be started with air pressure anesthesia (dermojet) or sedated anesthesia.
  • In the DHI method, prior canalization is not necessary in the area to be transplanted. The grafts taken from the donor area are placed in a pen-like medical device and the tip of this device is inserted into the transplantation area and a channel is opened. Then the grafts are placed into the opened channel by pressing the mechanism.
  • In the DHI method, crusting in the transplanted area is reduced and the healing time is accelerated.

WHAT ARE THE ADVANTAGES OF DHI HAIR TRANSPLANTATION?

  • With the DHI method, transplantation can be performed without the client having to shave completely. This is an important advantage, especially for female clients.
  • It is very easy to direct the hair follicles during transplantation with the DHI method.
  • In the DHI method, the damage caused while placing hair follicles in the area to be transplanted is minimal. Therefore, crusting is observed less in the treated area after transplantation.


DHI is preferred if the transplantation area is hairy or sparse. The reason for this is that the hair spaces can be tightened without damaging the roots in DHI. Since the channels are opened in the FUE and Sapphire FUE methods, the possibility of damaging the hair follicles in the hairy transplantation area is high and shaving is mandatory when applying FUE and Sapphire FUE techniques. Whereas in DHI, trimming the transplantation area is optional.
