No.4 Bond Maintenance Shampoo is built around OLAPLEX's patented Bond Building Technology™, using Bis-Aminopropyl Diglycol Dimaleate to help protect and repair hair bonds on a molecular level. This ingredient works to reinforce the disulfide bonds that give hair its strength, helping reduce breakage and strengthen hair over time.
Coconut oil-derived surfactants create an abundant, luxe lather that gently cleanses without stripping essential moisture, while Glycerin, Sunflower Seed Oil, Banana Extract, and Panthenol add hydration, softness, and frizz control. The sulfate-free formula is clinically proven to boost shine and reduce split ends and frizz.
Formulated for straight, wavy, curly, and coily hair types with medium to coarse textures across all porosity levels, this shampoo is vegan, color-safe, and designed to be followed by No.5 Bond Maintenance Conditioner for stronger, more manageable hair.
