For ages I have been using Nice and Easy warm auburn to dye my hair. Today I decided I wanted to try something a little more vibrant so opted for Garnier Ultra Colour 'intense red copper', which turned out to be nothing like it showed on the box. Instead of a bright copper, my hair has been dyed a very bright, unnatural red. How do I go about getting it back to a more natural, auburn shade? I've used a honey/oil/lemon mix which seems to have taken some of the brightness out of the shade. Would it be too soon to try using the Nice and Easy again? Thanks in advance.
