DHI Technique

What is DHI Hair Transplant? What are the advantages?

We will try to explain how hair transplantation with the DHI technique is performed objectively.


At first glance, the DHI technique, in contrast to the FUE technique; be described as a method in which two phases are carried out simultaneously. The hair follicles (grafts) that are transplanted from the donor area to the transplant zone without first having to open channels with a blade.


The implanter/Choi needle has a very thin, cylindrical and sharp tip.

This Choi needle with cylindrical tip has the shape of a channel. The hair along with the grafts can be placed in the needle.

The reason why the DHi technique is also known as the Choi method is the specialty of this needle.


Application of DHI method

In DHİ method, the collected hair follicles are placed one by one in the Choi pen.


This placement must be done very carefully. After placing each hair follicle, the assistants pass the Choi pen on to the specialist doctor to carry out the transplant. It is important that 40-45 degrees are maintained when placing the grafts because natural hair growth is taken into account.


The operation uses 2 to 6 choi pins and an average of 15-16 choi points. The tips of these pens can be of different sizes. The factor that determines this is the hair follicle and thickness structure of the hair.

DHI Hair Transplant Pros and Cons

First, let's talk about the benefits mentioned by experts:


-It ensures a healthier transplant by minimizing the residence time of the hair follicles outside the tissue.


-The survival rate of hair follicles is therefore greater.


-Since the incision area will be smaller, the risk of bleeding is kept as low as possible.


-After the hair transplant, a faster recovery can be seen, so that the patient can resume his daily routine in a short time.


-With this method, unshaven hair transplant can be performed more easily.

Disadvantages of DHI Hair Transplant Method

In order to properly use and specialize this technique, both the doctor and his team have to go through a very long training process.


-Compared with other hair transplant methods, it can be mentioned that  it is generally a more expensive method.


-The person who will perform the transplant must be careful and in good shape.


Is everyone suitable for DHI hair transplant?

This method was first developed at Kyungpook National University in Korea. Doctors specialized in hair transplantation have done research to better understand this technique and according to the results of the research they came to the conclusion that not everyone is suitable for hair transplantation with the Choi pen first developed and they found this application a difficult method.


They cited this situation as an example of the damage to the fine and curly hair follicles during implant tip placement and grafting.


Later studies produced implant pins suitable for more general hair types, not just those with straight, thick hair that is specific to Asians. The implanter pen used today has a wide thickness structure between 0.64 mm and 1.0 mm.


In the light of scientific and technological developments, hair transplantation can now be performed much more safely with Choi's tips. In specialized clinics, effective, predictable and, above all, natural-looking results can be obtained with hair transplantation with Choi tips.


Direct hair implantation, one of the most economical methods, is distinguished by a short recovery time and a large number of hair transplants in one session. Without damaging the healthy follicles, it is possible to obtain natural and dense hair by performing hair transplantation in places where there is no hair. Before application, the hair follicles are imaged with high-resolution equipment. With this imaging, characteristics such as the condition of the hair follicles, hair type and hair density are examined and the quality of the donor hair is determined.
