Introducing the innovative Purple Shampoo from L'Oréal Paris Elvive Colour Protect, proudly recognized as Britain's number 1 for coloured hair*. This expertly formulated shampoo addresses a common challenge faced by individuals with highlighted brunette, blonde, and grey hair: the inevitable appearance of yellow and brassy tones over time. These unwanted warm undertones can significantly detract from the vibrancy and freshness of your hair colour, making it appear dull and faded. Our unique formula leverages the fundamental principles of colour theory. On the colour wheel, purple stands directly opposite yellow. This scientific understanding is crucial, as the rich purple pigments within our Purple shampoo actively work to counteract and neutralize those undesirable yellow tones that emerge in coloured hair. Our new specialist colour-correcting Purple formula goes beyond mere colour correction; it deeply nourishes the hair while effectively neutralizing unwanted yellow, orange, and brassy tones in just one use. The result is hair that looks visibly bright and beautifully vibrant. It is perfectly suitable for blonde, highlighted, and silver hair, ensuring your colour remains stunning. *2018 Nielsen data, value & units, Haircare (client defined) 52 w/e 06/10/18 GB Total Coverage
