CAVIAR Style Perfect Iron Spray is a heat-activated spray that provides protection against hot tools while locking in moisture and sealing out frizz. This spray protects strands up to 450 °F/ 232 °C to prevent damage while heat-styling. By sealing and smoothing the hair cuticle, it helps to reduce frizz and lock out humidity, preventing style reversion, for sleek or curly locks that last.
