Sorry to bother you again, it's about that peroxide you told me about... I haven't been able to get to the store yet to look for it, but I have a bottle of peroxide at home that says "3%" and am not sure what volume amount 3% stands for, so was curious if the one I look for at the store will actually say "20 volume" somewhere on the container? Thanks.
just a small question for Marti...
