I read the points that Dr. Feller pointed out, and I think they are all good points. The answer is that we have to wait and see, statistically, whether this thing works with a LOT of patients. I'm sure there were some nay-sayers when the FUE procedure first came out.
I'd like to think that the hair follicle as a whole, and all of its parts - including that fatty, transparent, gel-like stuff around the papilla -are all strong enough to withstand the torsional force of the cutting tool, and the suction of the tube used to extract the follicle from the scalp, without breaking and/or dying.
Is this tool for sale to other hair transplant doctors? I wish other doctors like Dr. Feller would give this tool a shot to see for themselves whether it works. Use a small part of the scalp on their patients if there is doubt at first, and do the rest manually, like today's standard FUE technique. Only time will tell if the concerns of this tool are indeed valid, or if the other doctors who perform FUE hair transplants are just adverse to change.
Great post, though. Thanks a lot for sharing this. I hope this thing or later versions of it facilitate the FUE hair transplant for all of us, doctors and patients.
