Hair Transplant Using the Implanter Pen (Choi DHI Method)
A DHI hair transplant with the Choi Pen is a variation of the FUE hair transplant used in Turkey, mainly differentiated because of the use of a special medical tool known as the DHI Choi Implanter (also called Choi Pen). DHI is the acronym of “Direct Hair Implantation”.
When extraction technique was applied as a hair transplant technique, extracting follicles and implanting them was done using simple manual tools. Later on, the procedure was accelerated by introducing a machine known as "micro motor", which allows doctors to transplant more follicles by improving the extraction process, but has many disadvantages. Therefore, currently a new technique has been introduced using the Choi Pen in hair transplants.
What is a Choi Pen, and how does it work?
The idea of the Choi pen originated first at the Kyungpook National University in Korea; the idea behind this technique is simple: to combine in one process making channel incision dots in the recipient area and implanting the extracted follicles. Choi implanter is a pen-like device with a hollow needle at the tip of it, connected with a tube and a plunger.
During a hair transplant using a Choi implanter, the doctor loads the follicles extracted from the donor region into the implanter; the follicles are put gently, using tweezers, inside the hollow needle (at the end of the implanter pen). Then, the pen is used to implant the preloaded follicles into the scalp, and the doctor inserts the needle at an appropriate angle into the scalp and implants the follicle by pressing down on the plunger.
This process is then repeated to implant one follicle each time. During a typical transplant procedure, the doctor performing the procedure and the medical team working with him use about 6 Choi pens alternately to get the best result in a timely manner. Each of these implanters is equipped with various sizes of needles to fit single, double and triple hair follicle units.
Major improvements and advantages of DHI hair implant
Using a implanter for a hair transplant means that there would be no need to open channel incisions. The medical team previously needed to create tiny circular channel incisions in the head scalp and implant the follicles inside of them; but the doctor can now inject the follicles directly into the recipient area without the need to open the channel incisions, reducing trauma and bleeding during the hair transplant procedure.
As a result, doctors can now get higher rate of healthy follicles that stay viable and produce healthy hair later on, after the hair transplant procedure. In addition, this technique reduces trauma, resulting in faster healing for patients. There is obvious a significant evidence of better aesthetic results, as follicles can be transplanted more accurately during the procedure.
Below is a comparison between using the traditional hair transplant extraction method, and a hair transplant using Choi pens for the extraction process.
|FUE follicular units extraction|
|Follicles are extracted individually (one follicle at a time) and directly from the back of the scalp randomly, using specialized tools. When extraction is done correctly, this technique doesn't leave any scars. The donor area heals faster than in old traditional methods, like the FUT technique.|
|Follicular units Transplantation|
|Conventional extraction||Extraction using Choi pens method|
|Extracted individual follicles are implanted into the previously created channel incisions. The doctor creates channel incisions in the scalp, and then implants the extracted follicles in these incisions. The incisions created in the recipient area, in addition to transplant trauma, slow recovery, which also leads to a lower surviving follicles rate.||Individual follicles are preserved in high platelet-count solution. Then the follicles are loaded into a syringe shaped instrument and implanted directly into the scalp without the need to create channel incisions in the donor area, thus avoiding the trauma in the scalp. Using implanter pen increases surviving follicles rate.|
Why this new technique is better to increase hair density?
Using the Choi pen has also a major advantage to increase hair density, which is quite easy by implanting the follicles between the existing hairs. Many patients who are seeking a hair transplant as a hair loss treatment abandon the idea because the hair should be completely trimmed off before starting the hair transplant. This is necessary when using a micro motor to create the channel incisions before implanting the follicles.
However, when using a Choi pen the existing hair in the recipient areas no longer needs to be shaved. Choi implanters can be used to inject the follicles between the existing hairs easily. This method of transplant has another major advantage: when follicles are re-planted between the existing hairs, the doctor can clearly see the natural angle of the hair growth, and therefore he can perfectly position each follicle to match the existing hair.
These unique advantages of a transplant using a Choi implanter provides an exceptional benefit for beard and eyebrows transplant, too, as this technique gives the patient better aesthetic results in terms of density and appearance. But the most important thing is that it guarantees that there would be no scars on the face, since no incisions are created in the procedure.
Main advantages of the DHI (Direct Hair Implantation)
Besides the aforementioned, the main advantages of using the DHI technique are the following:
- Getting a higher rate of viable healthy follicles.
- Decreasing the bleeding while creating the recipient area.
- Decreasing the risk of an infection.
- Reducing trauma during follicles transfer, and causing less damage in the blood supply to the implanted area.
- Faster recovery after the hair transplant procedure.
- Reducing the time of procedure (with a medical team experienced in the Choi pens technique), as creating the incisions and implanting the follicles are both combined in one step.
Does the DHI hair transplant have any side effects or disadvantages?
According to the medical team of Clinicana, "there are no advantages or disadvantages; it's all about the tools that doctors use to carry out the hair transplant procedure. If you're good at using these tools, it will reflect on the procedure you're carrying out. Choi pen, Neograft, Artas and son on... all those techniques are just tools, you don't have to use any of these tools to get great results. You may use all these techniques and get bad results".
However, the main disadvantages of this method are:
- The doctors and the medical team should undergo a longer training period to master working with this technique.
- The medical team should consist of six persons at least for each procedure.
- The procedure may take longer time if the team is unfamiliar with this method.
- The cost of a DHI hair transplant is generally bigger than that of ca onventional extraction method, due to the cost of the Choi implanters.
- This technique requires more accuracy and attention during the procedure.
Is this new method suitable for all patients?
According to hair transplant experts, not all people are ideal candidates for a hair transplant using Choi pens during the extraction stage. After creating this method in the Kyungpook National University in Korea, it began producing good results in Asian people with hair loss, and then became a popular method in Asian countries.
However, although hair transplant using Choi implanters have shown good results in Asian people, doctors have noticed less success in other races. Experts have studied this phenomenon and reached the conclusion that Asian people's hair in general is distinguished with thick straight hair, unlike the curly hair with thinner diameter of other races; this means it can't be loaded properly into the needle of a Choi pen and implanted in the scalp.
This may lead to an inappropriate bend in the follicle, incorrect implant placement, and an excessive trauma for the follicles. Therefore, Choi pen method is not considered appropriate for all patients who want to undergo a hair transplant.
Why get a DHI hair transplant in Turkey?
It is important to consider that it's the doctor, not the used tools, what determines the results of a hair transplant. Even the most developed tools may lead to poor results when they're used by unqualified doctors. Choi pens may produce good results when they're used by a skilled, well-trained doctor in the use of this method.
Before taking a decision to undergo a hair transplant using Choi implanter pan, patients should know that this methods has many advantages but also disadvantages, and that not all people are good candidates for a transplant using this method (especially those of non-Asian descent).
