Yep I think you nailed it. To cover that much ground you have to take hair from outside a more dht resistant zone. He does so in a homogenous way so the donor doesn’t look depleted in one area more than the other. But who is to say what these hair transplants look like 30-40 years from now. Hopefully the same but we don’t have that evidence yet. I would love to hear what Dr Konior thinks of Dr Zarev technique? Would be really cool considering one is considered the greatest ever and Zarev is certainly heading into that territory for high norwoods.
