What is the DHI method?
The DHI Hair Transplant technique, which stands for "Direct Hair Implantation," is a method where follicles are implanted directly without the need for channel openings. This approach minimizes damage to the hair follicles since the grafts spend less time outside the scalp. Furthermore, the hair follicles are individually introduced into the receiving area at specific angles, resulting in a completely natural appearance.
The key distinction between the DHI technique and the FUE technique lies in the instrument used, known as the Choi pen or DHI implanter. The Choi pen features a hollow, round scalpel with a groove at the bottom to hold the graft. It also has a button at the top to release the hair follicles during the implantation process. This unique tool facilitates precise and controlled placement of individual hair follicles, enhancing the overall outcome of the hair transplant.
DHI transplant procedure
The DHI hair transplant procedure involves the following steps:
Consultation: The surgeon will first consult with the patient to determine the desired new hairline, considering the patient's preferences and the positioning of the forehead muscles.
Local Anesthesia: The patient will receive local anesthesia in both the donor area and the receiving area before proceeding with the transplant.
Hair Extraction: Using a specialized tool called a micro-motor punch, the surgeon will carefully extract individual hair follicles from the donor area, minimizing damage to the grafts. The follicles are preserved in a solution called Hypothermasol in preparation for implantation.
Implanter Loading (Choi Pen): The grafts are loaded into implanters, typically with the assistance of two surgical assistants to expedite the process. The Choi pen is designed with a hollow bottom to hold the graft, readying it for implantation.
Graft Insertion (Implanting): The surgeon uses the Choi pen to make incisions in the scalp of the receiving area and then releases the graft into the incision before removing the pen. Multiple pens are often used simultaneously during the surgery to increase efficiency.
Benefits of DHI Hair Transplant:
Natural Looking Results: DHI provides more natural-looking results due to the precise control over graft positioning.
Improved Density: DHI can achieve better density compared to other techniques, thanks to the controlled positioning of grafts using the Choi pen.
Enhanced Precision: The ability to control the angle and depth of implantation improves efficiency and graft survival rates, which are typically around 90-95%, higher than other techniques which range from 75-90%.
No Complete Hair Shaving: DHI does not require complete hair shaving, fulfilling a common request among patients.
Faster Procedure: The direct implantation with the Choi pen eliminates the need for channel openings, making the process faster.
Less Invasive: As the DHI technique does not involve incisions, it is less invasive to both the scalp and adjacent follicles.
These benefits make the DHI hair transplant a preferred choice for many individuals seeking a natural and effective hair restoration solution.
