Olaplex Nº.10 Bond Shaper™ Curl Defining Gel is an anti-frizz curl styling gel with flexible, medium hold and optimal slip for bouncy, smooth, strong, and hydrated curls, waves, and coils. Powered by OLAPLEX's patented Bond Building Technology™, the formula strengthens curl-forming disulfide bonds on a molecular level, reviving natural curl patterns for great curl days every day. This Costco exclusive 2-pack includes two 6.7 fl oz bottles.

Clinically proven benefits include 72-hour frizz control, 3x greater curl retention, and smoother, easier detangling. The humidity-resistant formula delivers crunch-free, frizz-free curls that hold all day while also providing 450°F/232°C heat protection and deep conditioning. In a consumer study, 90% of participants agreed their curls maintained hydration after 7 days of use.

To use, apply a small amount to clean, wet hair in sections. Scrunch upward to enhance your natural curl pattern. Air dry or diffuse until completely dry, then gently scrunch to break the cast for soft, frizz-free curls. The gel can also be used any time you restyle.

The formula is free of sulfates, silicones, phthalates, parabens, MIC/MIT, and protein. It is color safe, vegan, and cruelty-free, making it suitable for chemically treated and color-treated hair.
