I don't get the question.
Why would you want to take a shower after applying foam?
I shower twice a day. Once in the morning, once at night. I apply the foam after each shower.
So your question makes no sense...
Are you talking about waking up, taking a shower, applying foam, then going to the gym and needing a shower after that?
Then just apply your foam after your gym shower and do your next application before you go to bed..
Other than that I'm freaking baffled.
