The primary purpose of using heat protectant products is to shield hair from damage caused by heat styling tools. When hair is exposed to high temperatures from devices like flat irons, curling wands, or blow dryers, it can suffer from various types of damage, including dryness, brittleness, and breakage. Heat protectant products contain ingredients that create a barrier on the hair shaft, which helps to minimize moisture loss and prevent the high temperatures from directly affecting the hair's structure. This protective layer allows for safer styling, leading to healthier hair over time.

Other options, while they may include beneficial effects that can occur alongside the use of heat protectants, do not represent the primary intention of these products. Improving hair color or enhancing curling effects might be secondary benefits that some heat protectants could provide, but they do not capture the essential role that these products play in protecting against heat damage. Similarly, while some heat protectants may help decrease drying time, that is not their main function.
