The Advantages of DHI Hair Transplantation
When you decide to have hair transplant surgery, you start your own research to find out as much as possible about your options. This is a good idea, because you will be able to have a more detailed discussion with your hair transplant surgeon to find the best option for you. You may have found a lot of information about FUE (Follicular Unit Extraction) and FUT (Follicular Unit Transplant) hair transplantation, and you may have suddenly come across DHI (Direct Hair Transplantation) hair transplantation. DHI hair transplantation is one of the latest developments in hair transplantation.
What is DHI Hair Transplantation?
To understand DHI, you must first know the difference between FUT and FUE. In FUT hair transplantation, a strip of tissue with hair roots is removed from the back of the scalp and sutured to the recipient area. In FUE hair transplantation, there is no excision, a hole puncher is used to remove follicular units, and these extracted hairs are then implanted into the recipient areas.
DHI hair transplantation is a method of FUE hair transplantation, and the main difference is the way hair is placed. In FUE hair transplantation, the hair transplant surgeon makes incisions over the entire scalp and places the follicular units in these incisions. However, the DHI hair transplantation technique requires the use of a patented tool to implant the scalp each time without the need for any incisions. Alternatively, a robotic hair transplantation system can be used. This system calculates the depth and angle required for each hair follicle, that is why it is also known as robotic follicular unit extraction.
DHI Technique and FUE Hair Transplantation
DHI uses a special apparatus to precisely control the angle, depth and direction of the implanted follicle. This creates a completely natural hairline and a natural look.
In the DHI technique, the extracted grafts are implanted directly into the recipient area, while in the FUE technique, the extracted grafts are retained in a special solution, channels are opened in the recipient area, and then the extracted grafts are implanted in the opened channels. There is no additional channel opening step in DHI.
There is no bleeding in DHI because implantation is performed with a special Implanter without opening channels.
There is no crusting, pitting or postulation in DHI.
The maximum number of grafts in a session with DHI can be approximately 2,000 grafts and 5,000 grafts in FUE. Therefore, patients who need more than 2,000 grafts should accept multiple sessions with DHI.
Giving angle and direction is easier and more successful with the special implanter in DHI.
