Bond-building, science-led, and trusted by professionals worldwide, the Olaplex shampoo range actively repairs broken disulphide bonds within the hair structure with every single wash. For those managing brassiness, maintaining colour, or simply looking for a formula that does more than cleanse, shampoo with Olaplex technology delivers targeted toning alongside its core repair benefits in one step. The Olaplex purple shampoo neutralises unwanted warm tones efficiently and effectively, making it an essential staple in any colour maintenance routine regardless of hair type. Begin with Olaplex no 4 and build a bond-care regimen that addresses damage at a structural level rather than simply masking it on the surface. Ideal for colour-treated, heat-damaged, or chemically processed hair, shop the full range and give your hair the care it deserves.
