The Future of Hair Transplants

[Dav7]

I'm just wondering what level of progress is been made in the science of hair transplantation? It seems at present that we are still predominately stuck with the old donor method of hair transplantation, with all it's inherent limitations. However, is there any progress been made in the field whereby we are getting closer to a time when hairs from the face and body can be grafted onto the head, and done so that it looks natural in terms of appearance? I mean, how close would we be getting to the time when (a) hair transplants can be done with an abundance of non-depleting facial/ body hair and (b) a time when even a NW7 could go back to been a NW1?
