Should I Use Half a Dose of Minoxidil Since I’m Sensitive to It?

I have a simple question – If I will apply half the size of minoxidil 5% will it be as if I have used minoxidil 2.5%?

I ask this because I want to use rogaine foam which is available only in 5%, but I am very sensetive to minoxidil and want to use a smaller portion.

Thanks in advance.

You can try it and see if you are sensitive to a lesser amount. I would start with just a small amount if you are sensitive to it, but you may find that it isn’t effective enough to yield much regrowth. I know the Rogaine Foam is only available in 5%, but have you tried the 2% strength liquid Rogaine?
