Ideal, for grey, super lightened, or decolored hair, Blue pigment tones down unwanted orange hues on grey, light blonde, or streaked hair

No Yellow Mask is formulated with a special violet pigment that neutralizes undesired yellow reflections. Leaves hair soft, shiny and silky. The action of the violet pigment is not invasive but rather it has very high cosmetic action without any side effects, even if the shampoo is frequently used. Its acid pH seals the cuticle and creates protective violet film on the hair that reflects and rejects yellow reflection. It's perfect for conditioning action.
