I Bought Minoxidil, But its not a Foam?

You are fine. The only reason that the foam was made was so that Rogaine could market the minoxidil in a form that was protected by patent laws. But the active ingredient (minoxidil) is the same. And what you did was save money by getting the generic form of it. We've been using the liquid form of it for over 20 years, and if it doesn't regrow the hair, it at least helps to prevent further hair loss.
