Olaplex No.4FINE Bond Maintenance Shampoo 8.5 oz

Give fine hair fuller looking volume, softness, and strength with Olaplex No.4FINE Bond Maintenance Shampoo 8.5 oz, a lightweight volumising shampoo specially designed for fine, flat, and fragile hair textures. Powered by patented OLAPLEX Bond Building Technology™, this sulfate free shampoo helps repair damaged hair bonds while gently cleansing buildup and boosting body, shine, and movement without weighing hair down.

Unlike heavier repair shampoos that can leave fine hair limp or greasy, No.4FINE was specifically reformulated to provide weightless hydration and bond repair while maintaining airy bounce and natural movement. The concentrated formula gently removes excess oil, product buildup, and impurities while helping fine hair feel cleaner, softer, and visibly fuller after washing.

Specially developed for fine to medium hair textures, this shampoo combines volumising support with advanced bond repair technology to strengthen hair weakened by coloring, bleaching, heat styling, environmental stress, and daily brushing. Clinical testing shared by Olaplex reported that the No.4FINE and No.5FINE system helps instantly double visible volume and reduce breakage by 60% on bleached hair.

Beauty reviewers with fine hair especially praise how soft, clean, and bouncy the hair feels after use compared to richer repair shampoos. Many users also appreciate that the formula improves shine and manageability without flattening delicate strands.
