Repair and revive damaged hair with the Olaplex No.3 & No.4 Bond Repair Duo, a powerful two-step strengthening system designed to restore healthier, smoother, and shinier hair.
Olaplex No.3 Hair Perfector works as an intensive pre-shampoo treatment that rebuilds broken hair bonds, reduces breakage, and restores softness and elasticity. It targets damage caused by bleaching, coloring, heat styling, and daily wear.

Follow with Olaplex No.4 Bond Maintenance Shampoo, a nourishing, bond-repairing cleanser that hydrates while strengthening the hair from within. It boosts shine, reduces frizz, and leaves hair more manageable without stripping natural moisture.

Together, this duo transforms weak, dry, or over-processed hair into strong, smooth, and visibly healthier strands—delivering salon-quality repair from the comfort of home.

Perfect for: Dry, frizzy, damaged, colored, or chemically treated hair.
