Is your blonde looking a little brassy? There's no need to fret when OLAPLEX's No.4P Blonde Enhancer Toning Shampoo (250ml) can come to the rescue.

Powered by a cutting-edge toning system, this cleanser offers customisable blonde maintenance. Brimming with highly concentrated pigments, it lets you choose your toning level: the longer you treat, the brighter the results. It's suitable for all-over colour, balayage or natural blonde styles too. If that wasn't enough, this purple shampoo is also enriched with brand's patented Bond Building Technology, which works to transform dry, brittle strands into a soft, visibly shiny finish. No orange hues here...

Distribute evenly between palms first. Apply to wet hair and lather fully. Leave on for 1-3 minutes. (For more intense toning, leave on up to 5 minutes.) Rinse well and condition.

Founded in 2014 by Dean Christal, OLAPLEX has changed the landscape of the hair care industry. After employing two chemists to find a chemical that wouldn't damage dyed tresses, the team formulated the brand's proprietary, patented Bond Building Technology. Utilising this complex is the No.4P Blonde Enhancer Toning Shampoo (250ml), a purple-toned cleanser that helps to neutralise brassy tones while intensely moisturising and brightening tresses.
