I am naturally equivalent to a wella 4/0, i have been going grey for a few years now. Over a year ago i went to Bleached platinum blonde and want to go back to being dark (whilst i still can). I have been advised to use color touch 5.3 first then use a permanent dark with warmth in it. Can anybody give me some advise please. I suit the contrast of light or dark but don't suit coppers, reds(bright. vibrant) or light browns!!!
