As far as I know, there are basically only two ingredients commonly believed to work:
Minoxidil 5% and Finasteride 1mg
Finasteride usually comes in pills. It works well, but only on certain types of hair loss.
I think Minoxidil works for all types of hair loss. You put it directly on the skin that is losing hair. You can buy it as a fluid, foam etc. As the label says, the active ingredient in the "Rogaine" foam that PS3News posted is Minoxidil 5% as well.
If both Minoxidil and Finasteride work for you, then taking both is the best solution. One problem of hair loss is that you cannot really cure it, you can just stop and reverse it a little. So the effects will only last as long as you continue to use them. Stop taking it, and all progress so far will soon be lost again.
