DHI Hair Transplantation

Some define it as the newest method in hair transplantation, some say there is no ‘recognized’ technique called DHI, others claim that it is just a marketing gimmick, while a fraction explains the method as; FUE with implanters.

The debate goes further, where the two methods at its simplest form stand out to be; ‘different ways to harvest the grafts’ combined with ‘conducting different implanting procedures’.

However, our aim for this study is to remain objective and to have a brief and clear understanding on how the procedure actually works.

Unlike the FUE method, during the DHI implantation method, recipient site creation and graft implantation are performed simultaneously, i.e. extraction and implantation are combined as part of a one or two step process, embedding the extracted hair follicles directly into the recipient areas without the need of creating channel incisions via utilizing an implanter (Choi) pen.
The implanter/Choi Pen features a very thin and sharp fine tip.
This fine tipped Choi needle is shaped like a hollow needle and allows the grafts to be inserted within the needle.
This is why the DHI procedure is also referred as the Choi method.

A Complete Pain Relief Method in Hair Transplantation

DHI Hair Transplant

Thanks to the use of sedation given under the direct supervision of our Anesthesiologist, you will no longer feel any pain during the administration of local anesthesia prior to the hair transplant procedure. As a consequence, you will be having a more comfortable and pain-free hair transplant experience. Even though hair transplants are generally considered as painless procedures, this new method will help our patients who suffer from needle phobia, to feel at ease, allowing them to relax during the procedure. Owing to this, the level of pain that was currently at minimum is now completely eliminated.

What is Sedation?

Sedation is the action of producing a state of calm or sleep under controlled sedative drug administration, monitoring the depth of sedation with the types of drugs used and the amount given tailored specifically to each patient needs.

Do I Have to Receive Sedation?

Sedation is efficient and safe even in young children and as we previously mentioned, it assures the patient a discomfort free hair transplant procedure with zero pain. But then again, we continue to offer hair transplant procedures without sedation for patients who do not prefer. sedation to be administered.

The DHI method procedure

The DHI method procedure

  1. During a hair transplant procedure operated with the Choi implanter, the specialized physician/surgeon or technicians transmit the harvested grafts into the implanter pen.
    The graft is inserted gently within the hollow needle, which is positioned at the end of the implanter pen, to be handed back to the specialized physician.
  2. Subsequently, the needle is inserted at an accurate angle of 40-45 degrees into the scalp by the surgeon, as the incision site is made and then the graft is implanted by pressing down on the plunger.
  3. During a procedure, normally an amount varying from 2-6 Choi implanters and approximately 15-16 needles are concurrently used, with the device coming in a variety of needle sizes to fit the follicular unit grafts.

The Choi method naturally has its advantages as well as its disadvantages over the FUE technique.

Advantages of DHI Technique

Among its advantages indicated by some hair restoration experts are as follows;

  • Reduced time of grafts remaining outside the body, thus ensuring strong and healthy placement of the grafts.
  • Adequate hair follicles survival rates.
  • Reduced bleeding during the creation of the recipient area. Reduced trauma during graft handling, thus leading to less damage in the blood supply to the implanted area.
  • Fast recovery during the postoperative phase, the patient can return back to his/her normal routine quicker.
  • The recipient site does not have to be shaved, as it is a more suitable procedure that enables this condition.

Disadvantages of DHI Technique

On the other hand the disadvantages in comparison to the FUE method include;

  • The physician and staff members are exposed to long-term training period so as to specialize in utilizing this technique.
  • It is generally a more costly procedure when compared to other hair transplantation methods.
  • This method requires more attention as well as accuracy during the procedure.

The Stages of DHI Hair Transplant

After mentioning the highlights of this special technique, we will make one final remark on this topic through a question.

Are all candidates qualified to undergo this hair transplant surgery utilizing the Choi Implanter pen?

With the creation of this method by specialists at the Kyungpook National University in Korea, as the Choi Implanter is generally considered the ‘original’ implanter pen device, experts operating within the field started to conduct research so as to gain an in-depth understanding on this new technique.According to the results of their studies, they had identified that not all people were ideal candidates for utilizing the Choi implanter pen during the hair transplant surgery.

It was observed that the initial version of the Choi Implanter pen provided better results on Asian patients with hair loss compared to other ethnicities. The experts that studied this phenomenon came to the following conclusion: Asian people’s hair in general is distinguished with thick straight hair, and the curly characteristics and thinner diameter of other races, makes it difficult to be loaded properly into the implanter and place in the scalp, as the main sizes of the needles that were used in the early stages ranged between 0.8-0.9 mm.
As a result, this may lead to inappropriate bend in the follicle, incorrect graft placement and an excessive trauma for the follicles. Therefore, not all patients are ideal candidates for the utilization of the Choi implanter pen during their hair transplant surgery. SIn opposition to the proposed findings, some physicians disagreed with this statement, indicating that with increased training and experience with the Choi implanter pen, effective graft placement with any type of hair characteristics could be possible.

With scientific and technical advancements, hair restoration procedures has improved over the past decade, reaching to a point where it is now possible to conduct hair transplant utilizing the Choi Implanter pen with any kind of hair characteristics, creating a new era that produces consistent, effective, predictable, safe but most of all natural-looking results.

Hair transplant

The primary source of donor hair that is used in hair transplantation is located at the back of the head.
As the hair follicles in the region along the back of the head and between the ears are resistant to hair loss, they remain as the primary source of grafts used in hair transplantation.
The hair follicles extracted from the donor area does not grow back again, for this reason efficient utilization of the donor area remains the most significant element in hair transplantation.
Hair follicles are extracted from the donor area homogeneously so the donor site will not be noticeable after the surgery

Women opt for hair transplantation generally to lower their hairline or to add more volume.
Women are not required to have their heads completely shaved.
To carry out the extraction process only a small area in the donor site is shaved but will remain completely ‘undetectable’.
Women with long hair can easily conceal the donor area with their hair let down and this way, no one will be able to tell that they have undergone a hair transplant procedure.
For this reason hair transplantation is highly favored amongst women.

Where do they take hair from for a hair transplant? Where do they take hair from for a hair transplant?

Hair transplant

Follicles for transplanting are harvested from the donor area, which is usually the rear and sides of the head.
This area is also known as the "safe zone".
As the follicles on the sides and back of the head are not affected by the DHT hormone, they are not prone to hair loss.
When hair follicles are extracted from the donor area and transplanted to the areas that need coverage, they will be showing the same bald-resistant traits.
In cases where the donor areas remain weak and insufficient to supply the amount of hair for the transplant, then beard hair can be used as an additional donor resource for the procedure.
Beard grafts remain in the growth (anagen) phase for long periods and after the back of the scalp, are an excellent alternative donor source for hair transplantation.
Beard grafts are known to be thicker than the grafts at the back of the head.
For this reason, to provide better volume in the transplanted area, hair grafts extracted from the beard are transplanted in the top and crown area, but it may not be the best option for front hair restoration.

How long should I wait between two hair transplant operations? How long should I wait between two hair transplant operations?

For example if the patient has severe hair loss and bald patches are too wide to be covered, even if the patient wants to undergo a one session hair transplant procedure using the DHI method, he/she will be a better candidate for the FUE technique.
The reason for this is that the FUE technique enables to harvest higher amounts of grafts in a single session.

What are the differences between FUE technique and the DHI technique? What are the differences between FUE technique and the DHI technique?

Hair transplant

- DHI method replicates every step of the FUE method excluding incision and transplantation. In DHI the last two steps are merged into one.
- The major distinctive feature of the DHI method compared to other hair transplant methods is that the DHI technique employs a pen-like medical instrument called "Choi impanter" that creates the recipient sites and simultaneously transplants the grafts.
- FUE method allows to transplant around 3000 to 4500 grafts in a single session, whereas in the DHI technique around 3000 to 3500 follicular unit grafts can be transplanted during a single session.
- DHI method has a faster recovery period and can be performed with less bleeding compared to the FUE method.
- FUE method is ideal for covering larger areas, whereas the DHI method provides a better possibility for achieveing higher density.
- FUE method requires patients to have their heads completely shaved prior to the procedure, whereas the DHI method only requires the donor area to be shaved. This provides a significant advantage for female patients.
- The DHI method requires more skill and experience than other hair transplant methods. This in turn, requires the physicians and medical teams to be exposed to a long-term training period so as to specialize in utilizing this technique.
- DHI hair transplantation is generally a more costly procedure when compared to other hair transplant methods.

Good planning can be accomplished through proper location and design of the hairline, framing the face proportionately.
However, the hair quality of the patient and donor density are also important factors affecting naturalness.
Hair grows at different angles and in different directions.
In order to achieve naturalness, hair transplantation should be performed by taking the growth angle and direction of the existing hair into account.

Is PRP with hair transplantation defined as an organic hair transplant? Is PRP with hair transplantation defined as an organic hair transplant?

Hair transplant

Organic Hair Transplant is based on the idea of regenerating the transplantation area by injecting stem cell enriched fat tissue removed from the patient’s own body.
On the other hand, PRP is a special treatment that is applied after a hair transplant procedure.
PRP involves taking a small sample of blood and spinning it in a centrifuge to concentrate and separate the platelets and plasma from the other components of your blood.
In PRP, the concentrated plasma of blood including platelets, growth factors, leukocytes, and cytokine is injected back into the body at the injury site.
Hair transplantation supported with PRP enables tissues to heal faster, makes hair follicles remain in the active growth phase for a longer time and helps their adaptation to the transplanted area after the operation.
