Our Advanced Climate Control® All-In-1 Leave-In Conditioner is a lightweight, silicone-free conditioning spray that effortlessly removes tangles, primes curls for heat styling, and helps fight frizz in any climate. With powerful heat protection up to 450°, this multi-purpose leave-in spray helps prevent damage while also nourishing and hydrating hair with a shiny finish. It's infused with good-for-curl ingredients like hyaluronic acid and shea butter to boost moisture when detangling, as well as quinoa and pro-vitamin B5 to help strengthen strands. Our signature high-performance Anti-Frizz Nano Technology® with sericin, a protein derived from silk, forms an invisible barrier to block out humidity that causes frizz. “Nano” Technology refers to the size of the molecules in the formula, which are small enough to penetrate the cuticle and provide maximum frizz-fighting benefits. Safe for color-treated curls.
