I've been using the Rogaine foam for over a year, and now I've added the Spironolactone S5 Cream. My question is about application. Should I apply both at the same time, morning and evening? Or let one sink in first, before applying the other? Which goes on first? Does it matter?
I'm thinking chemical interactions and/or simple mechanics (a cream, for example, is pretty thick and could potentially block absorbtion of a foam if applied first).
This is all speculation on my part. I'm wondering whether anyone has any input on this.
