Thank you all for your kind advice. I know I am a difficult case but I would be just happy to improve my current situation. Even with my severe hair loss, using toppik, I am able to look decent, although it is getting more and more difficult. If I cant have a decent coverage, I may decide to keep using toppik, or to go for a scalp pigmentation. I have asked Hattingen, Pinto and Zarev for a consultation. I am also considering Resul Yaman and Bicer. They both have some interesting track record with NW6s. Clearly, the result if a transplant is subjective and there is no guarantee of a positive outcome, but at least I want to choose a reputable doctor and avoid scams. That is why this forum is so valuable to me and any advice is welcome. Thanks again!
