This heat-activated spray eases the styling process while providing a defensive shield for long-lasting frizz, static, and flyaway control. The weightless formula helps protect against thermal damage and includes antioxidant-rich argan oil and other naturally derived and upcycled ingredients to care for hair from the inside out, leaving it silky, soft, smooth, and glass-like—without a sticky finish or film. Powered by HydroResist Technology, which wraps strands in a hydrophobic conditioning veil that repels humidity and other environmental elements for perfectly styled hair that lasts for days. How to use: Spray throughout clean, damp hair. Comb to distribute evenly and blow-dry in sections to activate. Follow with a flat iron for enhanced anti-frizz benefits. Frizz Shield Spray should be the last product applied before blow-drying for optimal heat activation.
