DHI hair transplant technique gives the most natural look and hair density.
The potential for scarring and the risk of scabbing are considered minimal in DHI.
Significantly reduces the risk of bleeding at the recipient site.
Less trauma is caused to the grafts during surgery, resulting in healthier hair.
Since the recovery process in DHI hair transplant is very quick, patients can quickly return to their normal lives.
Ideal candidates for DHI hair transplant.
+ People who are experiencing hair loss and are over 18 years old.
+ People with good enough hair density.
+ People who need hair, eyebrow, beard, or mustache transplants.
What is DHI hair transplant?.
Direct Hair Transplantation (DHI) is one of the latest hair transplant techniques performed using the FUE hair transplant method combined with the DHI hair transplant pen or CHOI pen. DHI hair transplant uses the CHOI pen to control the angle, depth, and direction of each hair follicle being transplanted. The DHI technique does not require incisions because the grafts taken from the donor area are directly transplanted into the recipient area using the CHOI hair transplant pen.
Choi pen in DHI technique.
Choi Pen, also known as Choi hair transplant pen, is a pen-like medical device with a spring-operated mechanism and a 0.5-1.5mm hollow needle tip.
The CHOI pen is used to implant the harvested hair follicles into the scalp without making any incisions in the hair follicles. Therefore, the DHI procedure is divided into two main stages: hair follicle extraction and transplantation.
The CHOI pen allows precise control over the implantation of each hair follicle. This results in a precise result. Thanks to the CHOI pen, the grafts are harvested without waiting to be preserved in a solution. The hair follicles are attached to the pen immediately after being extracted and then implanted into the recipient area, increasing the survival rate of the hair follicles and the success rate of the hair transplant.
Compare DHI and FUE methods.
1. DHI hair transplant.
- In DHI hair transplant, CHOI pen is used.
- The grafts after being taken will be implanted directly into the recipient area, shortening the surgery time.
- 80-90 grafts can be implanted per cm2 in DHI.
- The maximum number of grafts in a DHI hair transplant can be around 2,500 grafts.
- Shaving may or may not be necessary in DHI hair transplant.
2. FUE hair transplant.
- In FUE hair transplant, micro-drill motors or steel blades are used.
- The grafts, once obtained, will be preserved in a special solution.
- 45-60 grafts can be implanted per cm2 in FUE.
- In FUE, the maximum number of grafts can be up to 5,000 grafts.
- Hair removal/shaving must be done in FUE hair transplant.
How is DHI hair transplant performed?.
DHI hair transplant is performed under local anesthesia. The treatment takes 6 to 8 hours for about 3000 hair follicles.
DHI hair transplant procedure steps.
1. Consulting.
The trichologist determines the characteristics of each patient during the consultation by considering the cause of hair loss, the pattern of hair loss, the likelihood of hair loss progressing in the coming years, hair type (thick or thin), the patient's expectations, age, gender, and medical history.
During the consultation, the hairline will be drawn based on the patient’s natural and desired hairline. The recipient areas are determined by the number of grafts needed in each area and the number of grafts that can be harvested from the donor site. Patients may or may not be eligible for DHI depending on their degree of hair loss.
2. Preparation.
Preoperative tests for HIV, Hepatitis B and Hepatitis C are done at this stage. The patient’s hair is then shaved. However, if the patient requires fewer grafts, shaving is not necessary. Once sterilization is complete, the patient is ready for local anesthesia.
3. Local anesthesia.
The surgeon administers local anesthesia before removing the cyst.
4. Hair follicle harvesting.
Hair follicles are extracted from donor areas using a micro-drill motor.
5. Insert the hair follicle into the pen.
The hair follicles are placed one by one in the CHOI hair transplant pen. The hair follicles are placed inside the needle tips without the need for forceps or tweezers to pick up the hair follicles.
6. Hair transplant into the scalp.
In DHI, hair follicles are directly implanted into the recipient area using a Choi implant pen with a diameter of 1 mm or less without any prior skin incision. Therefore, there is no need for an additional “hairline incision” step; the implantation and hairline incision are performed simultaneously using the needle tip in the CHOI implant pen. This results in shorter surgery time and less pain.
DHI hair transplant results.
If you have frontal hair loss, DHI hair transplant gives good results. Your doctor will advise you on the most suitable method. In which FUE and DHI are used together in one transplant.
* Results also depend on each person's constitution.
