Hi can any one advise me some colour correction, A client requested i matched the blonde that was left in her white hair, she had some dark regrowth at the back, I matched the colour and it looked lovely and even, but she hated it and said she meant she wanted to match the white / blonde in her hair ie ( the white) now she wants it lifting she is currently at a biege blonde 9, but is wanting a very pale blonde almost white, any suggestions i know high lift may only lighten it 1/2 shade and i dont think that is enough, or should i just lift it with a bleach 6%, any suggestions please ?
