Question

IF SO CAN I USE APPLE CIDER VINGAR INSTEAD.I READ THAT IF YOU HAVE COLOR TREATED HAIR U SHOULD B/C IT STRIPS THE COLOR.THAT MAKES SENSE JUST AFTER COLORING BUT WHAT ABOUT RIGHT B4 COLORING TO STRIP IT FORM ANY IMPURITIES N HAVE THE COLOR TAKE BETTER.ANY SUGGESTIONS ON WHAT TO USE.

Answer 1

Once a week is all you are supposed to use it
Nix the vinegar idea

Answer 2

I don't think that is a good idea. If you are blonde, it's fine. If not, it might strip the color.
