What Is the DHI Hair Transplant Technique?
DHI (Direct Hair Implantation) is a modern hair transplant method in which hair follicles are implanted directly into the recipient area using a specialized implanter tool known as the Choi Pen.
This technique allows for precise control of the angle, direction, and depth of each graft, resulting in a denser and more natural appearance.
Unlike traditional methods, DHI does not require pre-opening of channels in the scalp. This makes the procedure more controlled, efficient, and minimally invasive.
Which Hair Transplant Techniques Are Used at Hair of Istanbul?
At Hair of Istanbul, we personalize each procedure based on the patient’s hair type, degree of hair loss, and desired density. We offer the following advanced techniques:
- Sapphire FUE
- DHI (Direct Hair Implantation)
- Slit Method
Our doctors use high-resolution imaging to conduct a detailed hair analysis and select the most suitable method. In some cases, a combination of techniques may be used within the same session to achieve optimal results.

How Does the DHI Process Work?
Planning & Hairline Design: Every procedure begins with a personalized plan. The hairline is designed in harmony with the patient’s facial structure and muscle anatomy.
Local Anesthesia: Ensures a pain-free and comfortable experience.
Graft Extraction (FUE): Hair follicles are extracted from the donor area using a micromotor.
Graft Classification: Follicles are sorted into single, double, and triple units, then preserved in a special solution. For the hairline, only single grafts are used to ensure a natural result.
Implantation (DHI): The follicles are inserted into Choi implanter pens and directly placed into the scalp without prior channel opening. This enables precise and damage-free placement at natural angles.
Post-Operative Process
Operation Time: The procedure typically takes 6–8 hours
Bandaging: The donor area is bandaged and removed the next day. No bandage is applied to the recipient area.
Washing: Begins on Day 3, using special lotions and shampoo. Crusting usually resolves within the first 10 washes.
Products Used: Hair of Istanbul provides post-op care using selected Kerastase products, in collaboration with L’Oréal.
