...in the NY or DC area. I've tried many techniques and products on this board, and it seems to be helping except for the hair on my crown, the very top of my head. I have a bald spot there that will not grow no matter what I do. It's breakage, though, not a clean bald spot. there is hair there, but it's only a few millimeters long! I don't know what else to do. It will not grow, I've been to several dermatologists who didn't help. I want to try something else. Anyone have any ideas, or know of a good trichologist?
