Olaplex is all about the curls this spring 2026.

Whether wearing a curled version of the trendiest hairstyles of the season from shoulder length to a sculpted bob or “waterfall” hair, the hair care brand has released an innovation duo to keep curls healthy and shapely.

The No.4CURL Bond Shaper Hydrating Curl Shampoo and No.5CURL Bond Shaper Hydrating Curl Conditioner work to protect hair length by cutting frizz in half, detangling and significantly reducing breakage.

An iteration of the bestselling shampoo and conditioner at Sephora, both SKUs bring patented technology to the curl category formulated with its unique 3D Bond Shaper Technology.

Hydra-Define Technology

The product duo provides multidimensional strength from six different points, creating structural integrity and building strength in every direction so coils and curls stay resilient.

The product duo provides multidimensional strength from six different points, creating structural integrity and building strength in every direction so coils and curls stay resilient, wash after wash. This hydration-forward approach is powered by Hydra-Define Technology, which seals the cuticle to lock in moisture and block out frizz-forming humidity, keeping coils, curls and waves healthy until the next wash day.

No.4CURL Bond Shaper Hydrating Curl Shampoo is a silky textured, crème-gel shampoo with a fresh mint scent that creates a hydrating, non-stripping lather, repairing damage and invigorating the scalp for a fresh cleanse.

No.5CURL Bond Shaper Hydrating Curl Conditioner is billed a butter-soft conditioner that provides intense hydration and instant detangling, keeping curls smooth and frizz-free.

Hydra-Define Technology is a charged hyaluronic acid complex that neutralizes points of damage, sealing the cuticle to lock in smoothing hydration and block frizz-forming humidity.

Oil Mesh Network includes polymers that bind shine-boosting and manageability-enhancing oils to the hair cuticle. Its Natural Oil Blend comprises avocado and sunflower oils to impart moisture, softness and definition. Its Natural Silicone Alternative is derived from squalene-rich olive oil and provides enhanced slip and protection.
