What is the purpose of using a heat protectant spray?

The purpose of using a heat protectant spray is to shield hair from heat damage when styling. Heat protectant sprays contain ingredients that form a barrier over the hair shaft, which helps to reduce the impact of high temperatures from styling tools such as flat irons, curling wands, and blow dryers. These tools can expose hair to intense heat that can lead to dryness, brittleness, and breakage. By applying a heat protectant, you are effectively minimizing the risk of thermal damage, allowing for safer styling practices while maintaining the integrity and appearance of the hair.

In contrast, adding moisture to the hair during styling focuses on hydration, which is not the primary function of heat protectant sprays. Enhancing the hold of styling products refers to the ability of a product to maintain a hairstyle over time but does not relate to heat protection. Refreshing the hair between washes might involve using dry shampoo or other products designed to remove oil or add volume, which also does not pertain to the protection against heat damage during styling.
