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.

After washing the hair with No Yellow Shampoo, apply to the lengths and ends of towel-dried hair. Leave on for 3-5 minutes or until the desired toning results then rinse carefully. Apply once a week or when yellow becomes visible.
