I know chest hair isn’t as good as beard, but the survival is definitely much higher than %5. Even Dr. Camacho noted that they can get close to a 100% if they do a small number.
My biggest issue with medical literatures is that you’re relying on one surgeons expertise and experience, as we know. Surgeons are not created equal, their talent and results vary widely. 10 years ago there was a study that showed FUE grafts skeletonized. The grafts barely grew. Everyone referenced this study as proof that FUE was inferior. Well, now we know that isn’t true, and that particular surgeon wasn’t very good at FUE.
