The surgeons normally open these canals to place the donor follicles in the FUT and FUE methods. However, with the tool that is used in the DHI method, which is called Choi Implanter Pen, follicles can be directly implanted into the scalp. That is why this method is called Direct Hair Implantation.

Three Stages of the DHI method
Hair transplantation operations with the DHI method consists of three stages. The first stage is the collection stage, where the surgeons individually pick and extract follicles to be used in the recipient area. This stage is performed with a device called micro motor, similar to the FUE method.

With the help of this device, surgeons pick follicles from the patient’s donor area, which is usually the nape area. The reason why surgeons pick the nape area as the donor area is that the hair located in this area does not fall out. This feature makes them perfectly suitable for hair transplantation.

The second stage is the arrangement stage. This is the stage that makes the DHI method differ from the other transplantation methods. In this stage, the staff members carefully place the hair follicles into the Choi Implanter Pen. The time that the donor follicles spend outside of the patient’s scalp is reduced significantly during this stage. This greatly improves their chance of survival of the donor grafts.

The last stage is, of course, the plantation stage. In this stage, surgeons directly implant the hair follicles with the use of Choi Implanter Pen.
