Bye bye brass 

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 a protective violet film on the hair that reflects and rejects yellow reflection. It's perfect for conditioning action. 

What is it?: Deep conditioning toning mask formulated with extra violet pigment. Ideal for grey, super lightened, bleached, or de-colored hair.

What it does: Neutralizes yellow reflections while conditioning the hair, leaving it feeling soft, silky and giving it a cool, ashy, and vibrant tone.

How/When: After shampooing with the No Yellow Shampoo, apply the mask on damp or dry hair for 3-5 minutes or until the desired toning results then rinse. Use gloves to prevent staining of the hands.  Apply once a week or when yellow becomes visible.
