Olaplex No.4Curl Bond Shaper Hydrating Curl Shampoo

OLAPLEX N°4Curl Bond Shaper Hydrating Curl Shampoo (8.5 oz) is a multi-action shampoo for stronger, defined, and more hydrated coils, curls, and waves in one use. Patented 3D Bond Shaper Technology builds disulfide bonds from multiple points to repair, strengthen, and define curls, while Hydra-Define Technology, a hyaluronic acid complex, seals the cuticle to lock in smoothing hydration and block frizz-forming humidity. With nourishing avocado and sunflower oils, it reduces breakage, protects length, makes detangling easier, and provides up to 7-day hydration, cutting frizz in half even in high humidity when used as a system with N°5Curl. Free of protein, silicones, sulfates, SLS/SLES, phthalates, phosphates, and parabens. Apply to wet hair, lather, and rinse; follow with N°5Curl conditioner.
