I don't really know that much about the hair loss issue. But I really do feel for you. There is some vitamins at wal-mart, Hair, skin and nails, with extra biotin. I know that some things cause a deficiency in B vit and that can cause hair loss.
You might want to try those. You probably know it, but you can't expect immediate results with vitamins, it usually takes one bottle to start seeing results, for most issues that we take them for.
Keep us posted.
