What is the DHI technique?

The evolution of technology offers us different methods to solve the problems that we encounter in everyday life. This principle is also applies to baldness and several methods are currently available on the market, including the DHI technique, to tackle this problem.

It differs from other methods by the way grafts are implanted. The acronym correlates to "Direct Hair Implant" .

Definition of DHI/Choi technique

Although the FUE technique is more recognizable, the DHI technique is more advanced and may result in a more natural look. What immediately differentiates the DHI technique from the FUE is the insertion of the grafts. In FUE, the incisions and implants are made seperately, in contrast, in DHI, the incisions and implants are made simultaneously and it is not necessary to open the canals before the implant.

 

The process is accomplished by using an implant pen (Choi) that resembles an empty needle that is connected to a tube and a pushing device. Therefore, the DHI technique is also known as the Choi method.

The Implant Process

With the the DHI technique, the specialist inserts the follicles into the implant pen. The follicle is lightly inserted inside the empty needle, which is placed at the tip of the pen, and is then repositioned by the physician.

Then, the surgeon implants the needle at a 40-45 degree angle on the scalp while the incision is made by inserting the graft by pressing on the pushing device that is connected to the tube. Then, the surgeon inserts the needle at a 40-45 degree angle on the scalp. By doing so, the incision and the implant are made at the same time.

During the procedure, we will use between 12-14 Choi pens and 15-16 needles. The device comes in a variety of needle sizes to fit the follicular unit grafts.

Advantages of the DHI Technique

The advantages of DHI in comparion to FUE could be listed as:

• Less time that the grafts remain outside the body.

• Less bleeding.

• Less trauma during follicular insertion.

• Faster recovery in the postoperative phase.

• No need for shaving before the operation.

Seeing the scientific and technical progress, a new era has been begun that produces efficient and safe results, but most especially, a natural look. Because of these advantages over the FUE technique, the DHI tecnique has considerably improved hair restoration procedures.
