Thanks for your comments and the points you raise.
You will note that in my article I clearly state that it is possible to design transplantation experiments that would answer these issues properly. Was it just the one miniaturising follicle transplanted to the forearm? At what stage of miniaturisation was this follicle or follicles?
I would expect that any existing growth restricting chemistry induced by spatial controls in a follicle, to be maintained at transplantation until the follicle entered a new cycle. Then you would only get a new miniaturised follicle because of the miniaturised fibrotic scaffold created by the transplantation. This study does not contradict the tissue scaffold idea in transplantation, that is now a recognised factor in tissue engineering in-vivo.
Mouse studies that use a treatment to effect mouse hair growth (like the recent PGD2 study) are irrelevant to male pattern baldness. The big difference in the study I quote in my article is they used Human hair follicles in the mice. Any study that sees a significant regrowth of Human male pattern baldness follicles in an in-vivo model, is very relevant to Human male pattern baldness and has to be explained. The claimed differences in male pattern baldness follicles just cannot explain this, and are effectively refuted by this study. Why should these follicles not enlarge in the Human forearm, but significantly enlarge in the mouse tissue? The difference clearly has to be in the surrounding tissue, not in the follicle itself.
I agree preventing hair loss and re-growing lost hair are two different things. I think this is because once tissue edema gets established it is a lot harder to fix. There is also increased fibrosis longer term that adds to the problem.
I don't remember ever dismissing inverting the head for the reasons you state, and it is something I do myself combined with massage. We can "help" increase lymphatic drainage by these methods, but you have to deal with the actual cause of lymphatic restriction to make any real difference.
So what is the practical physical treatment someone losing hair today should be on to prevent or stop male pattern baldness from happening? propecia still? Most of the time with pages and pages of theory no real practical treatment really comes of it or exists to really physically apply that theory for real results. If not what is the point? Understanding is good but it doesnt solve physical problems
