The product essential for protecting hair from heat is heat protectant spray. This specialized formula is designed to create a barrier between the hair and the heat produced by styling tools such as blow dryers, curling irons, or flat irons. Heat protectant sprays typically contain ingredients that can absorb heat and reduce moisture loss, which minimizes the potential for damage to the hair's structure. By using a heat protectant, you help preserve the hair's health, shine, and overall appearance when subjected to high temperatures.

While other products like hair gel, hair mousse, and hair conditioner serve various purposes—such as styling, adding volume, or moisturizing—they do not specifically function as heat protectants. Hair gel and mousse primarily focus on hold and style definition, while conditioner aims to hydrate and nourish the hair. Therefore, when it comes to safeguarding against heat damage, heat protectant spray is the most pertinent choice.
