For me I took it for some weeks then stopped as it made my face go puffy, especially under my eyes, in those weeks my hair shed massively, but now the following two weeks OFF of it, the shedding is continuing, and i've got dandruff, hair is thinning a lot, i'm just hoping it'll come back within the next few months and stop damn shedding, because I never had one dandruff flake/shed before using it, really wish I never touched the stuff

Don't take my word for it though, other's have seen good progress on it, I don't wanna look like i'm going round slagging off the product, just saying my experience wasn't positive, and maybe if it didn't cause the side affects on my face and I rode it out it would've grown back thicker.
My theory is, I read somewhere that it shifts your hair into phases, so the weaker hairs get put to shed/sleep phase, to fall out and allow new, stronger hair growth...so maybe it shifted my hair into shed phase, and after this is over (which I really hope is soon..) they'll grow back like they were, don't quote me on that though, i'm seeing a specialist tomorrow, i'll tell you if they can 'shed' any light on it, haha xD
