You can also try Saw Palmetto, it also blocks DHT, but as it is a supplement, not a whole lot of studies have been done on it. It is cheap, and legal, though. You can buy it at Walmart. I've only been taking it for a few months, I don't know yet if there is any real change to my hair loss, maybe it's slowing it, I still have a full head of hair but a few spots are a bit thin. They haven't got any less thin, but haven't got any more thin. To an extent, they have always been a bit thin, as I naturally have always had really fine hair. One side effect, though, is that it's made me incredibly horny. This actually supports the idea that it is working, as if whatever mechanism that converts free testosterone is blocked, then one has more free testosterone. Maybe my aromatase is picking some of it and turning it into estrogen also, my moobs seem more sensitive, and maybe have grown.
