What is the DHI Technique?
The DHI technique, from English (Direct Hair Transplantation) is a variant of the traditional FUE technique.
Traditional FUE Technique
In the FUE technique, micro-incisions are made around each follicle to extract it completely. The micro-incision is made with a device called a “punch”. The follicles are then removed using special forceps. Finally, the follicles are implanted in the receiving area.
In the traditional FUE technique, the extraction of the follicles is performed first. This process takes between 1-3 hours depending on the number of follicles being removed. Then the implantation part is performed. The average implantation time is 1-4 hours, depending on the number of follicles to be implanted. Follicle survival depends on many factors, the most important being hydration status, temperature, mechanical trauma, etc. Studies have shown that there is an inverse relationship between survival and the time follicles spend outside the body.
In the DHI variant, the follicle extraction and implantation process is performed simultaneously. Therefore, theoretically, the time follicles spend outside the body is reduced and consequently the survival rate of the follicles is increased.
