Beck lost his hair due to his many other health problems, not due to MPB. I got pretty excited when i red it first a few years, but after some searching the people he work with (solatech or something similar) finally confirmed that his hair fell out because of his sickness and regrew as he got better.
It's an interesting theory, but it does seem a bit strange. I certainly don't feel like aiming a magnetic pulse rifle at my brain because it sounds dangerous, but who knows, perhaps there's something in that. O justk so i don't have to search for it and i'm sure you did research, are you absolutely sure it's not dangerous to use the rifle on your brain? I don't even use the blood purifier on my head.
Please keep us posted on your progress, and for the record, how old are you and how long do you suffer from MPB? Hair is funny thing, at first it will grow just because you iritate it (reason why a lot of snake oils seem to work for a few months) but pretty soon it's back to reality.
I like this method the best, couples with everything else that one feels it's good. It's certainly a great addition to any hairloos fighting attempt. Best of all it's free.
