I am aware minoxidil is an ingredient in Rogaine, but you can buy either one. Doctors will say for most hair loss patient Rogaine Foam is better option, but Rogaine is more expensive than minoxidil. Since either one has to be applied to scalp twice a day, I don't want to have to wait for any foam to settle like with Rogaine. What I want to something I can apply and go. Which is better in terms of convenience and price?
