Hair exposed to colouring, chemical services, heat styling and everyday stress needs cleansing, but it also needs a formula that does not leave already compromised lengths feeling rougher. OLAPLEX No.4 Bond Maintenance Strengthening Shampoo is a highly concentrated cleanser designed around the brand's bond-building technology.
The shampoo targets everyday damage and breakage while cleansing the scalp and lengths, leaving hair feeling softer and smoother rather than stripped. Its colour-safe positioning also makes it especially relevant for chemically treated hair where maintaining condition between salon services matters.
For shoppers comparing bond repair shampoo, shampoo for damaged hair or OLAPLEX haircare for coloured lengths, No.4 has a clear role as the cleansing step in a repair-focused routine rather than a generic everyday shampoo.
Who Is No.4 Best For?
No.4 is best suited to medium-to-coarse textures across straight, wavy, curly and coily hair, including all porosity levels. Fine hair may prefer a lighter shampoo within the OLAPLEX range.
