Incredible Foam Anti-Yellow Hair Foam Suitable for bleached, blonde and highlighted hair. Formulated with a special purple pigment that neutralizes unwanted yellow tones, giving hair softness, shine and silkiness. The mousse texture does not weigh down the hair and is particularly suitable for those with fine hair. Compared to the No Yellow Mask, it has a greater toning action and deposits more pigment to obtain a truly perfect blonde. Use: After washing the hair with the Anti-Yellow Shampoo, apply to wet hair on lengths and ends. Leave on: for 1-3 minutes on platinum blonde hair to clean the blonde; for 3-5 minutes on golden blonde hair to completely neutralize unwanted tones. Proceed to rinse. The special mousse formula creates a full-bodied and rich foam that hydrates the hair and, thanks to the Extra Violet Pigment, restores the blonde to its original splendor and beauty. Thanks to its mousse texture, it does not weigh down and is ideal for fine hair.
