Strengthening & repairing shampoo for dry, damaged and colour-treated hair
Olaplex No.4 Bond Maintenance Shampoo is a highly nourishing, bond-building shampoo designed to repair and strengthen damaged hair while maintaining essential moisture.
Powered by Olaplex’s patented Bond Building Technology™, this professional shampoo works from the inside out to help reconnect broken disulphide bonds caused by colouring, bleaching, heat styling, brushing and environmental stress. Hair is left stronger, smoother, and more resilient with improved shine and manageability.
Unlike traditional shampoos that can strip fragile hair, No.4 gently cleanses while supporting hair structure — making it ideal for regular use on damaged or chemically processed hair.

Professional tip
Consistency matters. Olaplex No.4 works best when used as part of a structured routine that includes bond repair, conditioning and protection. If hair feels coated or isn’t responding as expected, clarifying occasionally can help reset the hair before continuing your repair routine.
