Enriched with the brand’s original Bond-Builder System, the formula works to transform dry, brittle areas into soft, shiny and resilient strands. It helps to lend strength and manageability, all while illuminating your blonde. Saturated with highly-concentrated pigments, the best-selling purple shampoo allows you to choose your toning level: the longer you treat, the brighter the results. Suitable for all-over colour, balayage or natural blonde styles.
