Hi, you will probably think this is a dumb question, but I’ve been using Rogaine Foam for about a month now and I can never tell if I applied the foam to all the proper areas of the vertex. I’ve started putting the rogaine foam can in the refridgerator. After it has cooled down, it applies (without dissolving in my hand) onto my head quite well and the coolness is a good indicator of where it has been applied. MY question is, will the lower temperature effect the potency of rogaine foam? Thanks.

I had a patient tell me about his trick with Rogaine Foam — if you keep your hands cold (put them under running cold water for a moment) when applying the foam it doesn’t melt as easily… but I’ve not heard about using the cold as an indicator. I think it is a clever idea, but I do not know the answer.

I doubt a colder temperature would affect the potency of the minoxidil, but I’m unsure if the packaging is made to withstand the very cold. Proper storage of Rogaine Foam is at room temperature, between 68 and 77 degrees Fahrenheit. You can try getting better info from the source by writing or calling the maker of Rogaine via their website.
