After initial bleaching (40 vol) my hair is white blonde with orange streaks. Do I bleach it again to try to get an even tone before I add the Wella Illumina? I have no idea what I'm doing and I have my sister's wedding next week! I have some basic questions: 1. Should I bleach it again to try to get an even tone before adding the Wella Illumina? 2. Should I ditch 40 vol and get a lower strength? 3. Will the Wella Ilumina (which is lightest blonde) bring some color back to the white blonde in my hair and which developer strength should I use?
