Won't be easy to find a (good) surgeon to work on you, given your age and minimal loss; particularly, I wouldn't think they would densepack a bold hairline....which it sounds like you are seeking -- "my tight hairline back".
Anyways, post some pics if you can; as for FUE, I think that could be your best bet for sure if your loss (and personal physiology) dictate it....your choice of surgeon/clinic is much more limited, of course...*AND*, choosing well is all the more important as FUE is such a difficult procedure w/ gobs of deceit surrounding it.
But ya, for FUE, speaking of American doctors (I'm not sure I'd go to any in the UK), I firmly beleive that Dr. Feller is on the vanguard (FUE is what I initially wanted, fyi)....I've never seen results, but I've heard Dr. Rose performs high-quality FUE, as well.
