If you don't mind traveling to Baltimore Maryland, my brother and I both used Dr. Frank Weinstein and have had great results. My hair loss was not as dramatic as my brothers and now you would never know that we had transplants. I only needed one (so far) and my brother two. With the exception of an ichy head (which is par for the course), the experience was pretty quick and easy.
Dr. Weinstein does free consultations and is a great guy. I would highly recommend giving him a call just to get his advice. He's really good at answering questions and explaining how the process works and what to expect. (Promotional content removed by moderator)
Good luck with the research!
