Hair Scrunching Question!?

Don't brush it! It will turn it into a a sticky, frizzy/poofy mess and it will be hard to brush. I never brush my hair after I scrunch it until after I've washed it. I find that no matter how loose, if I put my hair in a ponytail overnight, it will leave a gross crease mark where the hair tie was, but you may be able to tie it back if you need to. I usually just kind of push my hair to one side of the pillow, away from my face and leave it down.
