Something that has helped my hair stop falling out is modifilan. Since your hair is falling out because of cancer treatment, I think that this might be something you would be interested in. You can read about it at their website and see what you think. It helped my hair get thicker, stop falling out, and get in better condition. I have a few other health problems which is why I started taking it, and after about two months I noticed that it was really helping my hair. One of my sisters has been commenting whenever I see her that my hair is growing so fast, which something that it never did before. It's a good product for hair, but it's also good for you in so many other ways.
