I think that someone has mentioned it earlier, but Minoxidil didn't work well for the person on that photos. That atleast get me big hopes for the Brotzu lotion (Minoxidil doesn't work well for me aswell).
Well as you've confirmed through Brotzu if that guy did get results with the same ingredients, at least that gives us a bit of optimism to carry us until its release where we can find out for ourselves.
