Will it be safe on purple tinted hair?
My hair is waist length and dyed very dark brown, almost black. The last couple months, my stylist has been mixing deep voilet in so that my hair has a purple shine to it in the light. Only problem is, as soon as any sulfate-free shampoo touches it, including Living Proof No Frizz, I have a tub full of purple water. No color comes out if I wash with just the conditioner. She thinks this may be happening because my hair is porous. Will this shampoo help keep my purple in there & not wash the rest of it out? Or can someone recommend a different shampoo? It's definitely not cheap to have this done.
