What's up with biosil not working for anybody? I've taken it and it definitely helps hair growth. As for skin I cannot tell because I am about to turn 25 and have not incurred much sun damage yet. But jarrosil seems to work equally well for hair strength/growth.So I guess the stabilizing agent (boron) is just as suitable as choline.
I think that it works for me. I've seen differences in both skin and hair since using it. That said, I haven't run a placebo controlled trial on it, and since it's systemic, can't do a split face experiment. There is published clinical data on it, however, and something is making me look better. I think it's the Biosil but I can't rule out other aspects of my regimen as being contributory. No doubt other things help as well. Still, I'm sufficiently impressed with Biosil that I will continue to buy it. In the liquid formulation it's a pretty good value, imo.
