Going to add my 2 cents. There is a difference between the top surgeons. I also don't the no there is a top 10. As an example, I have a top 5 for FUT, and I think they are all different and have different philosophies. I.e.
1. Dr Victor Hasson - known to get the most grafts in a single session, and he is the ideal choice for a higher Norwood patient wanting to get the most grafts and coverage in a single session. However, the Hasson hairline is very distinct (has a curve, and is conservative when compared with that off Dr Rahal)
2. Dr Wong, although is very similar to Dr Hasson, his hairlines aren't as good as Hasson, but Dr Wong is known to somehow produce the best crown results.
3. Dr Rahal is the best surgeon as designing hairlines, and is known to dense pack those smaller areas. He will almost always be very aggressive with the frontal third. He is the right fit if you just need frontal 3rd work done, but not so much if you want coverage over a larger area.
4. Dr Ron Shapiro, is much more conservative than the ones above, and he will dense pack less, produce a much more conservative hairline than Rahal and Hasson, and tends to go for coverage over density. his hairlines are outstanding as well, but they are much more age appropriate as compared to Rahal's youthful ones
5. Konior, I think he is the most conservative out of the bunch, but will produce better healed scars, and tends to do more with less grafts. So, he would be ideal if the donor supply is limited.
Hairs transplantation is an art, and there can be differences when surgeons design the hairline, decide on how dense to pack the grafts, and most importantly the angles which they use.
