Hello, I have a level 5 client who pulls orange. I try to get her to a level 8 but may have to drop her down to a level 7 to help lesson warmth. Using Wella I was planning 7/2 + 8/1 with a dash of /88 mixed with 20 volume. Any other Wella users out there have suggestions for lifting level 5s with the least amount of orange?
