DHI, or Direct Hair Implantation, is a hair transplant technique offered in Turkey. It involves extracting hair follicles from the donor area and directly implanting them into the balding area of your scalp. This method allows for precise placement of the grafts without the need to shave the head beforehand.
The pens that are used for direct hair implantation in Turkey are hollow and have a spring-loaded mechanism that pushes the tip when pressed. It then pierces the skin and leaves the graft inside. These special pens were first developed for fine hair and pens for thicker hair were introduced to the market later down the line.
DHI hair transplant is performed using a Choi pen during the creation of the channels. This small device, shaped like an interlocking ballpoint pen, has an outer Teflon coating and is designed to be resistant to temperatures of up to 130 degrees Celsius. The needle points at the end of the pen are where grafts are placed. This needle resembles an injector but is vertical, and the endpoints are serrated. The serrated ends are made this way so that the hair grafts can be placed into the needle before the transplant.
For an average DHI hair transplant process, 4 to 6 implanter pens are used. The method consists of two stages. The first stage involves placing the hair follicles into the pen. A specialist and two assistants take part in this stage, and it must be completed quickly. Hair follicles taken from the petri dish are placed inside the pen one by one. These hair follicles are placed into the needle by sliding.
The second stage involves transplanting the grafts placed inside the needle. The needle points with the grafts inside are approached to the hairless area with an appropriate angle, and the skin is pierced with the needle. At this point, the pen is pressed from the top. After the hair follicle at the needle’s end is pushed into the hole in the hairless area, the DHI hair transplant is complete.
It is important to note that, as with any application, a DHI hair transplant should be carried out by a specialist. The size of the holes pierced in the skin is of particular importance during the process, and there is no possibility of success if the holes are too big.
Advantages:
Disadvantages:
When compared to other methods, hair transplantation methods include intense hair follicles, the DHI method stands out as a better option. So, a more natural look and more intense look in terms of hair can be achieved. Additionally, with the help of Choi, it is easier in terms of adjusting the symmetry in the front hairline, which is of great importance in hair transplantation, lengthening the hair towards the original direction of growth, and opening the canals where the hair follicles are placed.
All these parameters required for a natural result are very easy thanks to Choi, but the expertise of the team operating is also the determining factor in the quality of the process.
