Although some sources accept the DHI (direct hair implant) technique as a new hair transplantation method, some sources claim that it is not a new hair transplantation method scientifically, but only a marketing tactic, and the FUE technique of the application is used with an implanter pen (choi pen). They say they have a different method.
DHI technique is also known as unshaven hair transplantation in our country.
“In the light of this information, if we summarize the DHI technique as follows, I think it will not be wrong;
We can define it as a different hair transplant method from FUE, as the DHI technique includes a transplanting phase different from FUE.”
HOW IS HAIR TRANSPLANTATION DONE WITH DHI (direct hair implant) / CHOI PEN / IMPLANTER PEN?
The most important difference of DHI (direct hair implant) technique from FUE technique is; It is a hair transplantation method in which two stages (grooving + transplanting) are performed at once, with the help of a special pen (CHOI PEN-IMPLANTER PEN) without opening any channels, of hair follicles taken from the donor area to the area to be transplanted.
The implanter/Choi needle has a very thin, cylindrical and sharp tip in shape and is designed as a normal hair follicle channel. Hair follicles can also be inserted into the needle by advancing along this channel.
The DHI technique is also known as the Choi method.
APPLICATION OF DHI (DIRECT HAIR IMPLANT) /CHOI METHOD;
The hair follicles collected in the hair transplantation operation performed with the DHI (direct hair implant) / CHOI method are placed one by one into the implanter pen.
This placement should be done very carefully and carefully (without damaging the hair follicles and hairs).
Afterwards, the assistants who perform the placement process place each hair follicle and give these hair follicles to the specialist doctor for transplantation.
The doctor who will do hair transplantation with CHOI pen, transplants the hair follicles at the most suitable angle of 40-45 degrees, and performs the transplantation of the hairless area. Apart from this angle, another important point is the right direction, which is very important in terms of obtaining a natural look with the angle. Therefore, it is necessary to plant in accordance with the direction of hair growth of the person who has had hair transplantation.
The hair follicles placed in the CHOI pen needle are planted in the area to be transplanted by determining the correct angle and direction, thanks to the retraction feature of the needle.
An average of 6-10 Choi pens and an average of 15-20 choi tips are used in the operation. The tip thickness of these pens can be in different sizes in accordance with the hair root and thickness structure of the person.
WHO ARE SUITABLE CANDIDATES FOR DHI/CHOI HAIR TRANSPLANT?
The DHI/CHOI method of hair transplantation first emerged at Kyungpook National University (KNU) in Korea. Doctors specializing in hair transplantation have conducted research to better understand this technique and, according to the results of the research, they concluded that not everyone is suitable for hair transplantation with the Choi pen/pen, which was first developed, and thought that this practice is a difficult method.
They cited as an example the damage of this condition, especially during the placement and transplantation of fine-wired and curled hair follicles at the implanter tip. In the subsequent studies, this problem was eliminated by producing implanter pens suitable for more general hair types, not only for people with straight, thick hair specific to Asians.
The choi implanter pens used today have a wide range of thicknesses between 0.64 mm and 1.2 mm.
As a result, today, in the light of scientific and technological developments, hair transplantation can be done much more safely with Choi tips to anyone who wishes.
In hair transplantation with Choi pens in specialized clinics; highly effective, predictable and most importantly natural-looking results can be achieved.
