Olaplex Nº.4P Blonde Enhancer Toning Shampoo - 250 ml

Specially formulated for blonde, grey, and highlighted hair, this toning shampoo uses highly concentrated purple pigments to neutralise yellow and brassy tones. While delivering vibrant toning benefits, it also strengthens and hydrates the hair from roots to ends. Olaplex Nº.4P Blonde Enhancer Toning Shampoo is suitable for both natural and colour-treated hair, leaving strands visibly brighter, softer, and more resilient. With regular use, it helps maintain a cooler tone and supports overall hair health without over-drying. The formula offers professional-level results, combining toning precision with patented bond-building care.
