    Hello, 

    how much % acid Violet ( sensient ) would you suggest for best toning shampoo like Olaplex, fanola etc… 

    sensient recommends 0.1 . But in my experience it’s not enough . 

    How much surfactant do you use ? Which quats? Share your exprerience please.

    thank you

    You are asking for a lot here, @Ahlmeyer
    Let’s just address the violet dye question. As it always happens in formulation, it DEPENDS ON THE APPLICATION medium, e.g. leave-in? rinse-out? shampoo? serum? “Blond shampoo”? Do you mean a color lift or brightening product? Sensient’s advice for 0.10% is spot on then. I’d be reluctant to use much more unless purple hair is the intention.
