Being on foam is like a roller coaster. This basically occurs because Minoxidil screws with your hairs shedding clock. You will experience months where your hair will look great, then the next 2-3 months can be hell with alot of shedding and your hair could look thinner than ever. (I experienced this and many others on this board also) but this is the most critical time and you must not stop applying the foam. If you ride it out things will improve greatly as it has for me. Unless you're a super fast freaky responder than expect to wait at least 12 months to see a noticable improvement.
