This heat activator spray is infused with rich ingredients like Macadamia nuts, vegetable fats and oil, and a powerful heat-activated polymer that provides an invisible barrier around the cuticle to seal in moisture and nutrients while locking out frizz caused by humidity. It detangles and softens hair while providing UV protection, making it safe for hair extensions and to add on after chemical services to help lock in color, repair damage and seal the cuticle.
