I've been using the stuff for about three months now. After the first month I had a massive shed and my hair looked like crap. Today I just did the two mirror thing so I could see my whole head. My hair looks a 100% better. I'm not sure what I am on the norwood scale but I can tell I've thinned out. Just wanted to say don't stop using the stuff if you have a massive shed. I almost stopped but now I'm happy I didn't.
