What professional product is often applied to protect hair during heat styling?

Heat protectant spray is designed specifically to safeguard hair from the damaging effects of high temperatures that come with heat styling tools like flat irons, curling wands, and blow dryers. These products typically contain ingredients that coat the hair shaft, forming a barrier that helps to reduce moisture loss and prevent structural damage caused by the heat.

When applied before styling, heat protectant sprays can help maintain the hair's integrity, making it less prone to breakage and dryness. This is essential in preserving the overall health and appearance of the hair, especially for individuals who frequently use heat styling tools.

Other choices serve different purposes; for instance, shampoo is intended for cleansing the hair and scalp, while moisturizer is more commonly used for skin hydration. Conditioner is useful for providing moisture and detangling hair post-shampoo, but it does not offer the same targeted protection against heat. Thus, heat protectant spray is the ideal product for preventing heat damage during styling.
