I exfoliate (use a facial scrub) once or twice a week, depending on how dry or dull my skin is. For every other day, I use a regular cleanser, like facial foam as you call it. How often do i need to use facial scrub and do i need to use facial foam before using the scrub?
Wash your hair before bed and in the morning. You don't HAVE to use a facial scrub. It's just a little cleaner. It is up to you how much you do it. More than once a day by scrubbing it is bad for you. I don't know why i think it's bad for you.
