Olaplex No. 4 Shampoo

Despite its chic, minimalist look, this remarkable bottle offers miracles. Far more than just a hair treatment, OLAPLEX's three-step ritual system permanently rebuilds the damaged disulfide bonds in your hair, compromised by coloring, heat styling, and daily wear. This daily cleansing and repairing shampoo deeply hydrates and strengthens hair while repairing broken bonds between salon or styling sessions, allowing you to maintain your favorite color and style without fear of damage. The No. 4 Bond Maintenance Shampoo is color-safe, sulfate-free, paraben-free, gluten-free, nut-free, and vegan-friendly. Use it after the No. 3 Hair Perfector weekly treatment and follow with the No. 5 Bond Maintenance Conditioner.
