I guess the foam does not work well to regrow hair this foam has been out for a while and no one has said the have had results from it.
I guess the foam was a way to improve sales for the Rogaine fooling all of us.
Foam hasn't been around that long...maybe 6 months? For those who were using the standard liquid version beforehand there's probably not a lot to report since it's a simple substitution (which makes life a hell of a lot easier).
For those who hadn't been using minoxidil before, 6 months is quite premature to be making judgements of efficacy.
