DHI HAIR TRANSPLANT TECHNIQUE
In DHI hair transplant technique, hair follicles taken from the donor area are transported to the area to be transplanted with a tool called implanter without opening the channel. Thus, the steps of opening the channel and transferring the collected hair follicles to the opened channels are done in a single step. This is the most important feature of the DHI technique that differs from the FUE technique.
It has a thin and cylindrical tip in the implanter shape. It is quite sharp. This Choi needle is shaped like a channel. Hair follicles are placed along the canal and placed on the needle. The reason why DHI technique is called as Choi method is due to this feature of the needle.
