Keep your blonde cool and bright: yellow undertones are a thing of the past. Enriched with active ingredients for a synergistic action, this cleanser is the definitive solution to say so long to the yellowing of blonde, white or bleached hair. The purple pigment contained within - together with Blueberry extract - work to neutralise the yellow undertones caused by the natural oxidation of the hair, delivering extreme brilliance and shine whilst maintaining the blonde or white tone of its original shade.
