Ouidad Botanical Boost Hydrating Curl Foam (210ml/7oz) Ouidad's Advanced Climate Control Featherlight Styling Cream creates definition and defends against frizz for long-lasting, touchable curls. The flexible and soft hold is thanks to a blend of lightweight humectants and natural oils (meadowfoam seed, olive, and soybean) that nourishes hair with balanced hydration to enhance curls. Our signature high-performance Anti-Frizz Nano Technology with 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.
