DHI Method (Direct Hair Implantation)
DHI method is the newest method in hair transplant. Extraction is the same with FUE method. They use micro motor for taking grafts, but implanting process is different. Doctors use an implanter ( choi) pen in implanting process. This is a choi tecnique. Thats why sometimes this method is called choi method.
Why this method is important?
Because doctors can get higher density in this method.
But we should not forget that DHI is for patients with low level hairloss, and patients under 40 years.
Doctors need to decide which patient is better for DHI ,and which patients are better for FUE (for example, 25 years old patient with hairloss only in the right and left corners, DHI can give a more density result . But for a patient with Norwood scale 5-6 hairloss stage, FUE will give a better result.
If we check on Norwood scale DHI is better for 2,3,4 hairloss stage and FUE is better for 5,6,7 hairloss stage.
With DHI ( Direct Hair Implantation ) hair follicles are implanted one by one directly to the thinning area that needs to be covered. Each hair follicle is placed in a specific direction, angle and depth, thanks to the DHI patented tool, the DHI implanter.
