DHI Hair Transplant Procedure: how it works, advantages, and side effects

ILAJAK Medical is committed to providing treatment by the latest medical technologies to its patients in Istanbul, DHI is one of the modern technologies for  Hair Transplant.

In this article, we will learn about this technology, important medical information about it, and a comparison between the prices of Choi pens in Turkey and the rest of the world.

What is DHI hair transplant?

Direct hair transplantation (DHI) or Choi pens is a modification of the FUE technique.

In the FUE technique, the surgeon does two things: manually open the canals in the scalp and then transplant the hair follicles.

Whereas DHI uses a dedicated tool called Choi pens that can do both at once

How does a Choi pen work?

Choi pens are pen-like instruments with a hollow needle at one end.

The surgeon or specialist uses it in the operating room to pick out hair follicles at the end of the hollow needle, then uses it to implant the previously extracted follicle into the scalp. This process is repeated for each follicle.

DHI hair transplant step by step

DHI is a modified version of FUE and follows a similar procedure.

The surgeon extracts hair follicles from a part of the scalp, usually the back of the head, and implants them in the balding areas. These hair follicles will eventually grow as new hairs.

Here are the practical steps for that:

DHI hair transplant step by step

  1. Shave the head and then apply local anesthesia.
  2. Extracting hair follicles from the back of the head.
  3. Pick out hair follicles with Choi pens and transplant them to the bald part of the scalp.

At ILAJAK Medical, we are keen to apply an antibiotic cream and a bandage to all the donor area and recipient area.

FUE and DHI surgeries generally take about 8 hours to complete, but the exact time may vary depending on the number of hair follicles being transplanted.

It may take 12 to 18 months to see the full results of the transplant.

After DHI hair transplant

After the hair transplant procedure, you may face some difficulties, especially in the first days of the recovery period, such as swelling, irritation, pain, and numbness.

To reduce them and get the best results, you should follow the following tips:

  • Clean the transplanted areas four times daily with a saline solution or water from a sprayer.
  • Carefully treat these areas overtime to remove the crust.
  • Avoid rubbing or scraping the crust.
  • Bathing is possible on the third day after the surgery.
  • It is important to use an appropriate, alcohol-free, or medicated shampoo and to avoid rubbing vigorously.
  • Do not let the shower water pour directly on the head. For the first week after the surgery, pour a cup of soapy water or plain water over this area.
  • Avoid combing your hair, you can start combing after seven days but be careful not to dislodge any follicles.
  • Check your vitamin and mineral levels.
  • Take nutrients as directed by your doctor.
  • Make sure that your hairdresser does not harm your hair while they are doing their job, whether it is cutting or styling.
  • Avoid exposing your newly transplanted hair to direct sunlight for the first two weeks.


In short, after the hair transplant procedure, you must take care of yourself and your scalp to get the best results.

We at ILAJAK Medical are keen to provide all tips in addition to vigorous follow-up to ensure the best results.

Advantage of DHI hair transplant

The following are the most important advantages of DHI hair transplant:

  • Reducing the time for the follicles to remain outside the body, thus ensuring a strong and healthy placement of the follicles.
  • Decreased bleeding during the creation of the receptor area.
  • Reduce shocks while dealing with the follicles. This results in less damage to blood flow to the transplanted area.
  • Recovery is faster during the post-transplant phase, in both the donor and recipient areas. The patient can return to their normal routine much faster.
  • Shaving the recipient area is not a requirement, therefore DHI is a more suitable procedure for people who want to keep their hair long. Keeping in mind, the donor area must be shaved.

DHI hair transplant side effects

Below are the common disadvantages of the DHI Choi pens technology:

  • Unfavorable reaction to anesthesia: Local anesthesia is applied to the scalp to numb it. Anesthesia is generally safe, but it may cause unfavorable reactions in some people. The vast majority of reactions are related to fear or anxiety rather than sensitivity to the anesthetic.
  • Infections: Serious infections are rare and occur in less than 1%, as it is possible to get an infection either in the donor area or in the recipient area where the hair follicles are transplanted.
  • Hair loss: It is medically called “shock”, where sudden hair loss can occur within two months of transplantation. Full recovery is usually achieved within about 3 to 4 months.
  • Unwanted appearance: When transplanting hair follicles, they must mimic natural hair. If the follicles are poorly planted, this can lead to an unpleasant appearance.


Some other side effects include bleeding, dizziness, pain. Increased heart rate, inflammation of the hair follicles.

To achieve satisfactory results, we recommend choosing a specialized center with a good reputation and previous successful customer experiences, you can find all of this and more in ILAJAK Medical.
