This Thermal Protecting Spray is designed to act as a barrier to heat while protecting hair from damage caused by blow-drying and heat styling tools up to 428°F. Hair is left smooth, shiny, soft and protected against humidity-induced frizz. Powered by an ultra-moisturizing combination of Jojoba Extract and Vitamins B3 & B5, this lightweight spray helps to combat the drying effects of styling products while acting on the surface and the core to nourish and improve hair's protective barrier for strong, healthy-looking strands. | René Furterer Thermal Protecting Spray, 5 fl. oz | Dermstore
