Olaplex Bond Shaper Curly Hair Set No.4CURL and No.5CURL

Bring your curls, coils, and waves back to life with the Olaplex Bond Shaper Curly Hair Set No.4CURL and No.5CURL, a high performance curl care duo specially designed to strengthen, hydrate, define, and reduce frizz without weighing the hair down. Powered by patented 3D Bond Shaper™ Technology and Hydra-Define Technology™, this advanced shampoo and conditioner system helps support healthier stronger curls while delivering long lasting hydration and enhanced curl definition. 

Unlike traditional curl shampoos that only focus on moisture, the Olaplex No.4CURL and No.5CURL system works on a molecular level to help repair damaged hair bonds while improving softness, manageability, and bounce. The sulfate free shampoo gently cleanses without stripping natural oils, while the rich hydrating conditioner helps detangle, smooth, and nourish textured hair.

Clinical testing shared by Olaplex reported that the system delivers 7 day hydrated curls, reduces frizz by 50% even in high humidity, and improves detangling immediately after use. Many reviewers also reported softer, shinier, more defined curls after just one wash.
