How long do you have to spray your newly pierced ears for?

The ear pierce hole never becomes permanent, it can grow in at anytime, but not in like only 2 nights. But if you don't have earrings in for about 2 months it can grow in....so don't worry about not having earrings in for a little while but it would be a good choice to have earrings in every once in a while! Hope this helped
