I did an FUT in 2010. I was told by a respectable clinic in Turkey I can do a second FUT, where the old scar will be cut, the surgeon will perform an incision on top of scar and remove it, and instead of old scar I will have a newer thinner one. How is this possible? I'm aware I can do an FUE on top of the scar. Unfortunately with FUE, I'd have to shave my head, which would make old scar visible. My long term plan is to do an FUE on top of scar but not now.
