For dry hair, the best heat protectants are hydrating, nutrient-rich formulas that protect up to 450°F while smoothing frizz and adding moisture. Top choices include Mielle Mango & Tulsi Thermal Protectant Spray for hydration, L'Oréal Paris EverPure Bond Oil-in-Serum for damage repair, and Kenra Professional Thermal Styling Spray 19 for use on dry, styled hair.
