Olaplex No. 4 Bond Maintenance Shampoo for Damaged and Color-Treated Hair 250ml

Bleaching, oxidative color treatments, chemical straightening, and persistent mechanical heat styling continually break delicate disulfide bonds within the hair cortex, leaving strands brittle, dehydrated, frizzy, and vulnerable to severe breakage. Olaplex No. 4 Bond Maintenance Shampoo 250ml 8.5 fl oz provides a revolutionary, salon-proven daily cleansing therapy engineered to rebuild and maintain internal structural integrity at the molecular level. Powered by patented bond-building active chemistry, it relocates and relinks fractured bonds, significantly enhancing tensile elasticity and preventing split ends. Its ultra-concentrated formula requires only a coin-sized portion to generate a lavish, dense lather that purifies the scalp, cleanses styling residues, and clears impurities without disrupting lipid reserves. It locks in weightless hydration, preserves color brightness and tone vibrancy, smooths frayed cuticles, and transforms compromised, dull hair into resilient, silky-soft, and luminous tresses that boast remarkable strength and effortless comb-through manageability.
