FUE and DHI are the two most popular methods used in hair transplantation. The classic FUE method involves a two-step process; first the recipient sites are made and then the grafts are transplanted. This two-step process may cause slight differences in terms of angle and direction during the transplantation process. In the DHI method, site creation and graft placement are performed simultaneously, i.e. extraction and transplantation are combined as part of a one step process, embedding the extracted hair follicles directly into the receipt areas. As a consequence of this, there is full control of depth, direction and angle of placement of each graft. Placement of grafts into the Choi implanter as well as the transplantation process requires comprehensive experience of the doctor.
Advantages of DHI Technique
Among its advantages indicated by some hair restoration experts are as follows;
Reduced time of grafts remaining outside the body, thus ensuring strong and healthy placement of the grafts.
Adequate hair follicle survival rates.
Reduced bleeding during the creation of the recipient area. Reduced trauma during graft handling, thus leading to less damage in the blood supply to the implanted area.
Fast recovery during the postoperative phase, the patient can return back to his/her normal routine quicker.
The recipient site does not have to be shaved, as it is a more suitable procedure that enables this condition.
Disadvantages of DHI Technique
On the other hand the disadvantages in comparison to the FUE method include;
The physician and staff members are exposed to long-term training period so as to specialize in utilizing this technique.
It is generally a more costly procedure when compared to other hair transplantation methods.
This method requires more attention as well as accuracy during the procedure.
The two methods have advantages over each other, and the doctor must decide on the management of the patient and should suggest which one is better. When DHI and FUE are done with the right doctors and the right team, they are not very different from each other in terms of naturalness except their technical superiority.
