Olaplex No.4P Blonde Enhancer Toning Shampoo 250ml

The best selling OLAPLEX Bond Maintenance Shampoo now comes with a brand new formula designed for blondes. Strengthen & repair while enhancing cool tones with No.4P Blonde Enhancer Toning Shampoo by OLAPLEX.

Protect and repair damaged hair and split-ends with the gentle cleansing and reparative OLAPLEX No.4P Blonde Enhancer Toning Shampoo. This brand new formula is designed to neutralise unwanted warmth between salon visits, revealing an evenly cool tone to all blonde hair types. With the ability to strengthen all types of hair, No.4 leaves it shinier and more manageable with every wash. Using the same patented ingredient as the OLAPLEX professional system, Bis-Aminopropyl Diglycol Dimaleate, No.4 works by finding single sulfur hydrogen bonds and cross-linking them back together to form disulfide bonds. Disulfide bonds are broken through chemical procedures such as colouring, thermal interference like heat and UV damage, and mechanical processes like brushing and combing. With this single active ingredient repairing and reinforcing the hair fibre, the result is stronger, healthier hair with enhanced colour longevity and vibrancy. No.4 Bond Maintenance Shampoo works seamlessly with No.5 Bond Maintenance Conditioner and No.3 Hair Perfector as part of the OLAPLEX 3-4-5 regimen for a professional treatment experience at home. OLAPLEX is colour-safe, vegan, pH balanced and completely free from cruelty, DEA, aldehydes, formaldehyde, silicone, parabens, sulphates, phosphates, gluten and nuts. Join the OLAPLEX revolution for a truly one-of-a-kind solution to restoring the natural texture of hair, boosting its elasticity and transforming its health.
