DHI Hair Transplantation

DHI is the newest method in hair transplantation. It is faster than the FUE technique and offers quicker recovery as well as stunning long term results. During DHI, the extraction and implantation are combined. Hair follicles are extracted and then embedded directly into the recipient areas without the prior need of creating incisions. This is done using an implanting device (the Choi pen). 

The Choi pen has a very fine, sharp tip. It 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 to as the Choi method. The device comes in a variety of needle sizes to fit the grafts of each patient.

As with all of our hair transplant procedures, we use sedation so that you can relax and experience a painless operation. You may opt out of sedation if you prefer to.

The DHI Method

These are the steps used to perform a successful DHI hair transplant.

The DHI method procedure

  1. The specialized physician/surgeon or technicians transmit the harvested grafts and donor hair into the implanter Choi pen.
  2. 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.

  3. Subsequently, the needle is inserted at an accurate angle of 40-45 degrees into the scalp by the surgeon. As the incision site is created, the graft is implanted by pressing down on the plunger.

  4. During a procedure, normally an amount varying from 2-6 Choi implanters and approximately 15-16 needles are concurrently used. They are handed between the physicians and their assistants.

The Stages of DHI 

 

Advantages of the DHI Method

Here are the biggest advantages of DHI hair transplants:

  • Reduced time of grafts remaining outside the body, thus ensuring strong and healthy placement of the grafts.

  • Excellent hair follicle survival rates.

  • Reduced bleeding during the creation of the recipient area. 

  • Reduced trauma during graft handling. This leads to less damage in the blood supply to the area with implanted hair.

  • Faster recovery during the postoperative phase, on both the donor area and recipient site. The patient can return back to his/her normal routine quicker.

  • The recipient site does not have to be shaved. Thus DHI is a more suitable procedure for people who wish to keep their hair long. Bearing in mind, the donor area does need to be shaved down, and will be done onsite, prior to the follicular unit transplantation.

Disadvantages of the DHI Technique

DHI does have one general disadvantage in comparison to FUE hair transplantation: It costs slightly more. This is because it requires closer attention and accuracy during the procedure. The physician and staff members have endured long-term training in order to specialize in the DHI technique, and thus the expenses are greater than a FUE transplant. However, by comparison to costs overseas, DHI hair transplants in Turkey are still an accessible price, and still promise the highest quality worldwide.

Are all patients eligible to undergo a DHI hair transplant?

The DHI method is available for nearly all patients seeking hair loss treatments. But this wasn’t initially the case. In early stages of the Choi pen technique, only a certain kind of hair type was usable: thick, straight hair. Luckily this is no longer the case, and people with all hair types can enjoy natural looking results. Here’s how we got to the current stage of universal DHI use.

The DHI method was developed by specialists at the Kyungpook National University in Korea. Their device, the Choi implanter pen, is generally considered the ‘original’ implanter pen device. 

Shortly after its creation, experts operating within the field started to conduct research, to best understand this new technique, and to see if it benefits all patients uniformly and universally. According to the results of their studies, however, they found that not all people were ideal candidates for utilizing the Choi implanter pen during hair transplant surgery.

In the initial transplants using Choi pens, it was discovered that Asian patients with hair loss received better results compared to other ethnicities—largely because of the texture and thickness of their hair. The experts came to the following conclusion: Asian people’s hair (in general) is distinguished as thick and straight. On the other hand, the curly characteristics and thinner diameter of other races, makes it difficult to load their hair properly into the implanter, and to simultaneously be planted in the scalp. The sizes of the needles that were used in those studies ranged between 0.8-0.9 mm.

Without the proper diameter and straightness, follicles could experience a bending effect, or could lead to incorrect graft placement and an excessive trauma for the follicles. Therefore, it was reported that not all patients are ideal candidates for the utilization of the Choi implanter pen during their hair transplant surgery. 

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, and on any reasonable number of grafts.

So, yes, nearly all patients may opt for a DHI implant method if they choose, and can experience the same consistent, effective, predictable, safe, and natural-looking results as those initial Asian patients. Hair growth timelines are similar for all patients, too.

Does hair grow back in the donor site after the hair transplant is done? Does hair grow back in the donor site after the hair transplant is done?

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

Hair transplant

A hair transplant is usually carried out under local anaesthetic, which means you will not feel any pain. As of 2019, Dr. Serkan Aygin Clinic has started to carry out hair transplantation with sedation so as to make their patients feel more comfortable during the operation. In hair transplantation combined with sedation, as the patient will remain awake without feeling any discomfort, he/she will not feel the graft extraction, recipient site creation and transplantation processes. The patient undergoes the procedure without feeling any pain or discomfort.

When will I see the results of my hair transplant operation? When will I see the results of my hair transplant operation?

Hair transplant

After a hair transplant procedure, the amount of time required for recovery, healing and growth of the new hairs, is extended over a period of 12 months.
Between 2 to 3 weeks after a hair transplant procedure most patients experience a phenomenon known as “shock hair loss“, where the new hair grafts enter a resting phase and the hairs are shed.
This is a perfectly normal and natural process that most patients experience after a hair transplant procedure. There is nothing to worry about.
After the shedding of the newly transplanted grafts your new, healthy hairs will soon begin to grow in their place.
In about 2 to 2.5 months your transplanted hair will be entering its normal growth cycle and grow approximately 1.5 cm every month.
From 9th month onwards, the transplanted hair will improve in texture and at the 12-month mark, it will get thicker blending with the person’s own natural hair structure.

Will I lose hair after a hair transplant? Will I lose hair after a hair transplant?

Hair transplant

The only shedding experienced after hair transplantation is a phenomenon called “shock loss”. Shock loss which occurs after about 2 to 4 weeks following the hair transplant procedure, is a result of a short-term trauma occurring in the transplanted hair follicles and scalp after the operation. It is an inevitable process seen after transplantation. This is a normal and temporary condition. Even if the transplanted hair falls out during the phase of shock loss, the follicles are not be damaged and provide the required space for new hair to grow.

Do you have hair transplant services for women patients? Do you have hair transplant services for women patients?

Hair transplant

Although the majority of hair transplantation patients are still men, a high percentage of women have also started looking into a hair transplant procedure as a hair loss treatment.
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.

How long do I have to wait to go back to work after the procedure? How long do I have to wait to go back to work after the procedure?

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?

Hair transplant

We advise waiting at least 6-7 months between sessions with 12 months being ideal.
Because in order to create an operation plan for the second hair transplant procedure, the results of the first hair transplant should be seen first.
A one year period is required to achieve maximum growth of the newly transplanted hairs and for all the incision marks to be undetectable.

Which hair transplant method should I prefer? Which hair transplant method should I prefer?

Hair transplant

During your initial consultation, the physician will determine which transplantation method is best for you based on your hair loss classification, the size of the thinning area, quality and quantity of your available donor hair.
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.

Will my hair transplant results look completely natural? Will my hair transplant results look completely natural?

Hair transplant

When a hair transplantation procedure is performed by an experienced physician and a professional team, the results will ineluctably look natural.
Obtaining natural results from hair transplantation depends on good planning.
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.

When can I cut or shave my hair after the hair transplant procedure? When can I cut or shave my hair after the hair transplant procedure?

After one month you can shorten your hair with a scissor or clipper.
We advise you to wait for six months to shave your head with a razor blade.

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.
