what do you mean no guarantee in scar revision? i haven't really looked into this..but i have heard of it. i have only 1 scar..but my wife has seen it more than i have (she cuts my hair). she says it's not very wide and not awful...but what does she know. =) FUE stills seems like the more logical/long term way to go, but i still want to explore EVERY option before i make a final decision.
