Thermal Protector 44 Iron Guard works from the inside out to protect hair from thermal damage and breakage, thanks to a lightweight formula that doesn't weigh hair down. By sealing the cuticle, it prevents future damage while leaving hair smooth and shiny. This spray creates a powerful barrier against the heat of styling tools, strengthening hair's resistance to damage. Enriched with ceramics and proteins, CHI sprays offer exceptional protection, adding strength and shine for a healthy look. All CHI products are cruelty-free, paraben-free and sulfate-free, reflecting the ethical commitment of the brand, founded by Farouk Shami.

Section your hair and spray it with CHI 44 Iron Guard evenly over dry hair. Start using your heat tool from roots to ends. Can also use on wet hair before drying.
