So my colleague is colouring my hair in a few days and was planning on using a bristle brush combing on technique with blondor to prelighten ends, (I have seen this done but neither of us have tried it yet). I'm a base 6 with a lot of stubborn warm pigments in my hair. Looking for advice on colour recipes for a flat ashy brunette tone. I'm not long back from maternity leave so I'm out of touch with grey colour recipes. Im wella trained but not overly familiar with the newer illumina colours or the innocence range. I was thinking 8/69 and Pastel, but worried about going a khaki grey with the warmer undertones. Maybe darker like 7/81 would be better? I've always been warm in tones so fancied a bit of a change. New mum.. new me .
