The Direct Hair Implantation (DHI) method
The Direct Hair Implantation (DHI) method is a modern technique used in hair restoration surgery. It is a variation of the traditional Follicular Unit Transplantation (FUT) and Follicular Unit Extraction (FUE) methods. The main difference between the two is the way in which the hair follicles are transplanted.
In traditional FUT and FUE methods, the hair follicles are extracted from the donor area and then transplanted into the recipient area using a needle or a punch. In contrast, the DHI method uses a special instrument called a Choi pen, which allows the surgeon to directly implant the hair follicles into the recipient area without the need for a needle or a punch.
The procedure begins with the surgeon extracting hair follicles from the donor area, typically at the back of the head. The extracted hair follicles are then placed into the Choi pen, which is a device that has a small hole on the tip, where the hair follicles are inserted. The Choi pen is then used to directly implant the hair follicles into the recipient area, which is usually the scalp. The procedure typically takes several hours and is done under local anesthesia.
One of the main benefits of the DHI method is that it results in a more natural-looking hairline compared to the traditional FUT and FUE methods. Additionally, the DHI method allows for the use of smaller incisions, which can minimize post-operative pain and reduce recovery time.
Another advantage of DHI is that it allows for the implantation of hair follicles in a more natural angle and direction, which is more similar to the natural hair growth.
However, DHI requires a higher level of surgical skill and experience. Additionally, it may be more expensive than the traditional FUT or FUE methods.
Overall, the Direct Hair Implantation (DHI) method is a modern technique that offers several benefits over the traditional FUT or FUE methods. It can provide a more natural-looking hairline and minimize post-operative pain, but it is important to consult with a qualified and experienced hair restoration surgeon to determine if this method is the best choice for you.
