In opinion I think dr koray didnt answered any of the questions people put forward. He just sounded like a business man. Who is focusing to make money rather than to build reputation.
Having said that I personally believe hes still producing consistent results but not as consistent as it use to be and these days with dr koray it feels like the greater the hair loss. the better the result which I find strange^
However I also think people should study each hair transplant individually. They should consider the question whether they are genuinely poor results. Is it too early to tell? is it in fact realistic in line with their circumstances ? Does it look natural or pluggy? They should consider the hair type, donor hair, design and angulation, number of grafts considering the area that needs coverage before labling as bad result
