So long, heat damage! Cantu's Thermal Shield Heat Protectant protects hair of all types and textures from damaged caused by flat irons, blow dryers, and other heated styling tools. Specially crafted with pure shea butter, the Thermal Shield Heat Protectant adds moisture to strands to create smooth, frizz-free results. When hair is protected from heat damage, strands become stronger and healthier with a natural shine. This heat protectant shields hair from temperatures up to 425°F, and strengthen strands to prevent breakage and promote hair growth. The Thermal Shield Heat Protectant serum reduces frizz and flyaways while also adding a light hold. To use, spray on damp hair before blow drying or air drying. Dry hair completely, and then lightly mist hair evenly in targeted areas, section by section, before using a flat iron, curling iron, or other heated styling tools.
