Well, I think you need to understand what type of hair transplants are available. And there's two types: there's FUT, which is follicular unit transplantation. And FUE which is follicular unit extraction, the if you see is one where they took the strip from behind the ear of the ear from one side of the ear to the other. And they take a strip of hair and then divide all the hair follicles so that they can be implanted. The FUE is a specialized technique where you take individual hair follicles so there's no strip, you don't have to make big cuts. And neograft is a specialized machine and technique where it's a much faster, less complicated system to actually take those hair follicles.
