Olaplex No.4p Blonde Enhancer Toning Shampoo 250ml

The Olaplex No.4P Blonde Enhancer Toning Shampoo is a purple toning shampoo designed specifically for blonde, silver, and lightened hair. Part of the renowned Olaplex Treatments collection, this 250ml shampoo does more than your average toning formula — it works to neutralise unwanted yellow and brassy tones whilst simultaneously helping to repair and strengthen hair bonds from within, which is the hallmark of the Olaplex system.

This shampoo is ideal for anyone with bleached, highlighted, or naturally light hair who wants to keep their colour looking cool, bright, and freshly done between salon visits. It suits all genders and works beautifully on coloured and natural blondes alike, as well as those with grey or white hair who want to maintain a clean, vibrant finish.

The formula lathers gently and can be used as part of your regular wash routine or left on for a few extra minutes when you need a more intense toning result. It pairs perfectly with the rest of the Olaplex range for a full bond-building haircare programme.
