DHI hair transplantation is a hair transplantation procedure also known as the pen technique. There are certain points that distinguish DHI hair transplantation technique from other hair transplantation techniques. In all of the hair transplantation techniques, hair follicles (grafts) are collected from the nape between the two ears or the donor area, the collected grafts are then placed in the recipient area after micro-channels are opened. DHI implants the extracted grafts directly by placing the needle and creating an opening simultaneously with special implanters. This is the most important point that distinguishes this technique from other techniques.

If we talk about the advantages of DHI hair transplantation technique;

One of the most remarkable advantages is that the area where hair transplantation is planned can be does not need to be shaved.

When the operation is performed with the DHI hair transplantation technique, the micro-channels are not opened separately after the grafts are collected, and are directly implanted. This minimizes the time the grafts are outside the body. Hair loss is reduced during and after transplantation. With the implanters used in DHI hair transplantation technique, angle and direction are easier to determine.

Hair transplant is a surgical method of treatment for androgenetic alopecia. The hair follicles in the occipital scalp are collected and then implanted to the anterior scalp and less often to the apex. There are two methods for extracting follicles from the occipital scalp. DHI, the newest of three methods of hair transplant, is available.

DHI hair transplant advantages

With DHI hair transplantation the roots can be implanted closer to each other. As a result, the appearance after the transplantation will be close to natural. Special tools and equipment used during the procedure help to keep the scars at minimum.

Since hair transplantation can be made directly to the areas in need, DHI could be beneficial for those with ongoing hair loss. It is possible to open the channels and implant the grafts at the same time.

With all this, DHI hair transplantation is really a method that requires experience and attention. For this reason, it may be slightly more costly than other hair transplantation methods. But the naturalness and quality to be obtained as a result will be worth this cost.

Hair transplantation studies and developments

DHI Hair Transplant Turkey There have been many innovations in the current medical practice of hair transplantation. The concept of FUE or Follicular unit extraction procedure was first described by Rassman et al. This method has the advantages of preventing scarring and reducing pain after surgery. However, there are disadvantages of increased surgical time, graft fragility, and increased cost to the patient.

In 2006, a surgically developed follicular extraction (SAFE) system was developed. The average rate of 6.14% is quite low. This new innovative device was introduced by Harris. All the pioneers in this field have developed their modifications for the extraction technique and have been defined variably as the Wood, FUSE and CIT techniques.

Studies after hair transplantation

There has been great progress in the field of hair transplantation surgery to optimize results. Bernstein et al. suggested some key points to consider for maximizing graft survival.

First, the graft remains sensitive to injuries from the moment it leaves the body and is completely safe in the recipient area (ie, up to the 8th postoperative day). In another study, it was stated that the probability of mechanical graft displacement decreased on the 6th day and there was no risk on the 9th day. They showed that preventing crust formation reduces the time at which the graft is at risk of displacement.

Second, it emphasizes the importance of continuous supervision of staff throughout the procedure for optimal results. Other factors that reduce graft survival are mechanical injury, dehydration, chemical solutions, heat and hypoxia. Dehydration is the most damaging injury.

DHI hair transplant procedure

The FUE procedure was made possible and called DHI hair transplantation. The standard FUE procedure involves three steps: Graft extraction, followed by creation of channels in the recipient sites, followed by graft implantation.

However, for DHI hair transplantation technique, the above mentioned event order has been changed. First, the recipient area is prepared, and then the procedure for graft removal and immediate graft implantation is initiated.

DHI hair transplant  procedure phase 2

In the 2nd stage for DHI hair transplantation, when the patient’s head is in an upright position, grafts that are difficult to remove and implant are made only by the doctor.

As the physician is the most experienced member of the team, difficult grafts are not wasted and are implanted without mechanical damage. While the physician performed the difficult parts, the surgical assistants are also busy with removing and placing the grafts. Thus, more people work at once and the whole process is better regulated to ensure better graft survival.

Finally, unlike the standard FUE procedure, there is no need to store the grafts in any storage solution, saline, or platelet -rich plasma.

Comparison of DHI hair transplantation and FUE

DHI Hair Transplant Turkey In the standard FUE procedure, the time it takes for the extraction of all grafts ranges from 1-3 hours. After that, the time it takes to create the recipient areas ranges from 15 to 30 minutes and from 1 to 2 hours for graft implantation. Therefore, the duration the grafts are outside the body varies from 1 to 2 hours.

However, in the DHI hair transplantation procedure, the planning, extraction and implantation stages are initiated simultaneously, allowing the grafts to stay outside the body between 2 and 20 minutes. It takes from 10 to 25 minutes to complete 2 stages of DHI for every 100-150 grafts.

Frequently Asked Questions
Who performs these procedures, and where?
Hair transplantation is a process performed in hospital surgery rooms by aesthetic surgeons using local anesthesia.
Is hair transplant harmful?
Hair transplant surgery is normally safe when performed in suitable surgical conditions by qualified, experienced surgeons using proper medical devices board.
What type of skincare is necessary prior to hair transplant?
If the patient has an active scalp condition, this must be treated before the surgery, in the presence of active acnes, antibiotics must be used, excess dandruff must be treated, and in the case of potentially precancerous active lesions; specimens are collected for biopsy, and sent to pathology laboratory for further tests. Wig or prosthetic hair should be discontinued to use one to two weeks before hair transplant surgery, if it is fixed on the scalp with an adhesive or glue this must be rinsed off. Using cosmetics such as hair gel and topic should be discontinued. Using solutions to prevent hair loss such as minoxidil must be stopped one week before surgery. Patients should note that they will get a haircut in the clinic prior their hair transplant procedure.
Who is a candidate for hair transplantation?
Everybody who suffers from hair loss, and has adequate donor hair can undergo this procedure. The FUE procedure can be recommended for patients who enjoy short hair, want to have more number of grafts transplanted in one session, and do not want to have a scar in the form of a straight line in the donor area. The FUE procedure is also recommended for the patients who have previously undergone FUT or FUE procedures. The FUE procedure is very suitable for patients who have a small bald area around the hairline or crown, and who will be prone to the risk of hair loss, and therefore, will need a second or third procedure in the future.
Who is not a candidate for hair transplantation?
Any systemic health condition that is contraindicated with local anesthesia must be treated before the procedure. The procedure is not recommended for patients who do not have realistic expectations and adequate donor hair. Any active skin conditions must be treated before the procedure. The patient must have normal blood levels of B12, B6, and zinc, and any thyroid diseases must be treated before the procedure. Blood sugar levels in diabetic patients must be kept under control.

Will the hair shed after hair restoration surgery?
Hair shedding can begin anything from three to four weeks after hair restoration surgery. This is called shock loss. In fact, productive follicles are transplanted. These follicles remain under the skin and start producing hair as hair shedding occurs. They start growing nearly three months after the surgery. They do not grow at the same time. Growing density continues nearly five months to eight months, increasing gradually. Conditions such as symmetrical growth, an area became denser before the other, and an area thinner than the other are expected. It will not be fair to make a judgment in this period. One should patiently wait as the final outcome of hair restoration procedure will be more evident after eight months. The scar tissue will become softer, and consequently redistribution and thickening of hair strands will be observed between from eight months to one year after the surgery. In comparison with the eighth month, the look is apparently more natural one year after the surgery. It may be good to wait for around one year to see the natural-looking outcome. A male pattern hair loss is out of question, because they are not affected by the hormone DHT.
