Yes Dr Feller, Dr Cole and Dr Lindsey are from the US. It depends on the nr of grafts. I would guess between 10-15 USD per graft when you have to get them in a scar, but not sure could be cheaper - I paid 7 USD per graft approx for FUE but that was in virgin scalp. Guess you would minimum need 500 graft, but I have not seen any pictures, and I am not an expert on scar repair. Keep researching and keep looking and asking. Good luck. Cheers
