Harvesting 7600 Grafts from a Beard??

Hello Doctor

a very well known doctor claims that he was able to harvest 7600 grafts from a patients beard and transplanted it to its scalp. Now is that possible?

I have done several beard to hair transplants and they are relatively easy, but I really don’t know if the beard contains 7600 movable grafts. Is it possible? I suppose. Some people may have very high density hair in their beard.
