DHI Hair Transplant (Direct Hair Implantation) Technique

DHI Hair Transplant (Direct Hair Implantation), also known as DHT (Direct Hair Transport) is a technique that is developed to minimize the transport duration between a collection of grafts and implantation. In this technique, the hair grafts are extracted smoothly and individually from the collection site with the help of micro punches and planted in the hairless area. There are many different aspects that determine the survival rate of the collected grafts. Researchers observed that these factors improved if the graft’s transit duration was reduced. Therefore, in 2013 a group of researchers modified the FUE technique that the individual grafts are implanted right after they are collected. Since then, some calls this “a new method” and others call it “a modification or subtype of the FUE method”.

The DHI Method with Choi Implanter Pen

In the DHI method, the collected hair follicles are transplanted with a special device that is called Choi Implanter Pen. Therefore, sometimes people refer to the DHI method as the Choi pen method. Choi Implanter Pen is the original device that is developed by Kyungpook National University in Korea. At first, it was not very widely received by the hair transplantation community due to taking a significant amount of time. However, some surgeons prefer to use this pen due to their increased control over the angle of grafts that are going to be implemented. CHOI pen has a needle that is between 0.5-1.5mm in size. The size of the needle is chosen by the surgeon according to the hair features of the patient. After being collected the grafts are loaded into this pen. Both canal opening and implementation are carried out with this pen.

Stages of DHI Hair Transplantation

DHI Hair transplantation steps are very similar to FUE hair transplantation except for the site creation and graft implantation is performed simultaneously. DHI Hair Transplantation steps can be summed up as follows:


In this stage patient is physically examined by a doctor. This doctor determines the final hair transplantation plan and hairline design. Some physical and oral examinations are held. In this stage, the doctor can tell you if the DHI method is suitable for the expected results. Blood is taken and sent to the laboratory for the necessary tests. These tests ensure that the patient does not have any medical conditions that prevent him from having surgery.


Before anesthesia normally preparation step involves hair-cutting but in the DHI method this is optional. The transplantation site is disinfected. This step takes about 30 minutes. Then, local anesthesia is administered either by needle or needleless (if the patient prefers needle-free Painless Anesthesia Comfort in the system, he will receive virtually no pain during the process.)


In this step, a device called micromotor is used to collect hair grafts. Unlike the other hair transplantation techniques, there is not a step involving canal opening. These grafts are immediately suitable for transplantation. The collected grafts are examined under the microscope and are grouped according to how many follicles they have.


The hairs are placed and planted to the receiving site by the use of a Choi Implanter Pen. This pen can both open the canal and transplants the hair.

Post-operative Procedures:

PRP (Platelet Rich Plasma) procedure (which strengthens the hair follicles) and the wound dressings are applied.

Post-operative Hair Wash:

During 30 days after the surgery, the hair should be washed according to the appropriate conditions. After 10 days the crust will be gone and will accelerate the process.

NOVE MIC® Method

In the arrangement step, as described earlier, grafts are separated according to their follicle number. For the most natural look, one follicle containing grafts should be transplanted into the hair frontline, whereas the others should be transplanted to the banding sites.This step is a very important stage of the transplantation which is taken for granted usually by other hair transplantation centers. Usually, many centers carry this separation process manually which causes false counts. In EsteNove, we use MIC NOVE® system for the separation process. After being collected, our grafts are counted and grouped under the light microscope. Therefore, the margin of error decreases to 0. This ensures that patients have the most natural look and are more content with the results.

Differences Between DHI and Sapphire FUE Techniques

The choose of hair transplantation technique depends on many factors such as the number of grafts needed, cost, recovery time, etc. Therefore, when comparing DHI vs Sapphire FUE, telling one method is superior to others will not be completely true. Moreover, many centers using the FUE technique, use different devices which effects the result. The most advanced type of FUE is sapphire blade FUE which uses sapphire blades to open canals.

These blades cause less scarring and a more natural look than steel blades using FUE methods. In DHI method instead of blades, CHOI implementer pen is used.The main difference between the two methods is; during the hair transplantation operation canal opening is not a separate stage in DHI and it is performed right after the extraction phase. However, if a person needs more than 2000 grafts of transplantation, the DHI method cannot be used in one operation. The main advantage of DHI is it has a faster recovery period and no scarring. In the Sapphire FUE method, if the donor area is suitable, the maximum number of grafts can be implemented.

Advantages and Disadvantages of DHI Technique

Like all the different hair transplantation technique DHI method has its own advantages and disadvantages. Some advantages of DHI;

  • Faster recovery period
  • No scarring
  • High-density follicle transplantation
  • No shaving necessary

Where are some disadvantages of DHI are;

  • Maximum 2000 graft in a single session
  • High cost
  • A significant amount of time during operation
  • Since the learning curve of the DHI technique requires more time, if the person making the DHI hair transplant does not have enough experience, Choi may damage the ends and other hair follicles

DHI Hair Transplantation Recovery and Results

The recovery time is very short after the DHI method. Patients can continue their routine life after the operation. The results start to show after 6 months following the operation. Usually, the hair on top of the roots that are planted with the process starts to fall off after 2 weeks to 2,5 months, and after 3 months the newly transplanted hair starts to grow. All kinds of hairdressing services should be postponed for 6 months. Our patients have outstanding results.

FAQ About Hair Transplant in Turkey

In general, hair transplant is carried out under local anesthesia, so the patient does not feel any pain or discomfort during the transplantation period. Also, there is a most advanced needle-free injection system called Comfort-in™ is used in hair transplant operations in EsteNove and it makes the hair transplant operation painless.

Yes, hair transplant is a safe and fast-growing industry in Turkey. First of all, hair transplant clinics in Turkey have state-of-the-art technology, a high level of knowledge, more experienced surgeons and staff and the patients’ feedback is positive. Also, in Turkey, it is performed in international accredited hospitals by premium clinics. Besides that, in Turkey the hair transplant clinics adopt a solution-oriented approach, so the patients’ satisfaction is at the top level. In Turkey, there are 44 JCL certified hospitals and it is placed on the third worldwide with this feature.

Whether a person is a good candidate for a hair transplant procedure is determined through with hair analysis (such as hair tissue, hair follicles quality, hair density, elasticity, pores, skin texture) and examination results. In this respect, after considering all factors such as patients state of health, the frequency of the donor area and the width of the area to be planted, it is understood whether a person is suitable for hair transplant.

Hair transplant can be performed at any time as well as the patient feel ready physically and psychologically. Patients, who want the aesthetic appearance, can have hair transplant at any time if the donor area is sufficient. In patients with hair loss, it is expected that to hairless areas will be intervened in advance and will not lose the aesthetic appearance of the hair. Because after a certain point, if hair loss reaches an extreme level, it becomes difficult to obtain an aesthetic image after hair transplant. In this respect, 1 or 2 more sessions can be applied if it is necessary. Also, we recommend PRP treatment in order to stop further hair loss.

During the hair transplant process, grafts are collected from the donor area where the transplant will be performed and looked them under the light of the microscope. Then, the grafts are separated. Generally, in many hair transplant clinics, the grafts are separated manually. Considering 3-4 thousand hair follicles, in this case, the error rate can be very high. Therefore, in the Nove MIC® method, the hair follicles taken from the donor area are divided into groups containing 1, 2 and 3 roots with the help of a special microscope. Only single grafts are transplanted to the front line of the hair. Thus, the transplanted area is exactly the same as the old hairline of the patient and so natural appearance occurs. That is to say, by the Nove MIC® method, the mistake risk is minimized and patients reach the most natural results.

Yes, women can also have a hair transplant, but the cause of hair loss needs to be well diagnosed. Because of androgenetic alopecia, known as male-type hair loss, hair loss resulting from the regression of the forehead line of the hair or an opening in the crest, women can also have hair transplantation.

Technically, there is no age limit for hair transplants. So, hair transplant can be applied to everyone from 22 to 65 years of age. But we cannot say, all people in this age range can have a hair transplant. Therefore, the determinants are hair type, hair loss condition and the general health condition of the patient.

Yes, we give a guarantee for after post-operative results, excepting health conditions or therapy that causes patients hair loss. In addition, patients should also follow the post-operative instructions given by the doctor.
