About this product

Olaplex No.4P Hair Brightening & Toning Purple Shampoo is a concentrated formula designed to neutralize brassiness and repair everyday damage in natural or color-treated blonds and grays. It enhances shine, evens tone, and strengthens hair with bis-aminopropyl diglycol dimaleate, which rebuilds broken bonds. The hydrating lather cleanses gently while improving softness and resilience. This shampoo works on straight, wavy, curly, and coily textures across fine, medium, and thick hair types. A bright, citrusy fragrance blends grapefruit zest, sugared mint, ginger, and crushed sage.
