Olaplex No.10 Bond Shaper Curl Defining Gel is a flexible medium-hold styling gel designed to define waves, curls, and coils while controlling frizz, maintaining hydration, and supporting stronger-looking hair. The formula features patented Olaplex Bond Building Technology with Bis-Aminopropyl Diglycol Dimaleate to help strengthen hair and repair damage by supporting the disulfide bonds responsible for hair structure and resilience. A Curl Retention Compound combining humidity-resistant flexible polymers, plant collagen, and sugars creates a curl-locking barrier that enhances definition, smoothness, shine, and lasting shape without a stiff or crunchy feel. Coconut-Avocado Hair Milk provides fatty acids and conditioning nutrients to nourish curls, improve softness, and help reduce breakage. The high-slip gel helps detangle and distribute evenly through wet hair while providing up to 72-hour frizz control and humidity resistance, heat protection up to 232°C, and clinically proven 3x greater curl retention. The formula dries without visible residue or flaking and is vegan, color safe, silicone free, sulfate free, paraben free, protein free, and suitable for chemically treated hair.
