I have a client whose hair will not take with Wella Illumina, after 4 attempts. Her hair is 100% white, fine and in good condition. I have used 10/36 with one third base 9, tried with Welloxon 6% and also 9% processed for 30 mins, tried longer. Colour appears to take, but after 1 week it is completely washed out as if it was never coloured..Not even on the roots so it is not a porosity issue. Please advise what the possible causes could be? (She is not on any medication and does not expose to sun, also wella brilliance shampoo.) Thank you.
