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:
- Shave the head and then apply local anesthesia.
- Extracting hair follicles from the back of the head.
- 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.

Our Team
Mustafa Yilmaz
My vision of hair transplantation is totally in line with this perspective: to be at the service of regained well-being through effective techniques that give natural results. The hair, in women of course, but in men, it is the force of life, it is the finery. Losing them is truly an injury, a trauma. It’s terrible!
Also, I enjoy listening to my patients and never judging them. I am then able to give them the best advice and allow them to regain their self-confidence.
I naturally surrounded myself with a caring, expert and extremely rigorous team in its field to be sure to offer men and women who suffer from baldness solutions that work, without ever ignoring safety and reliability.
The used techniques depend on Dr. Mustafa Yilmaz decision after doing the medical diagnosis, Choi Pen / DHI - Sapphire - Micro FUE are used normally in our operations.
Emine Karabash
I started dermatology almost 15 years ago now and thanks to my encounters with other dermatologists, I quickly turned to medical aesthetics.
More and more women and men want to feel good about their hair, and when this is the case, one gains confidence in oneself, in everyday life, in social life and in work.
I have also always remained "classic", in this movement that is now called the "Soft touch", namely to privilege discretion, elegance, and of course, naturalness. Not ostentatious! I prefer to repair what is damaged, rather than change or modify.
The used techniques depend on Dr Emine’s decision after doing the medical diagnosis, Choi Pen / DHI - Sapphire - Micro FUE are used normally in our operations.
