Heat protectants are hair care products designed to shield hair from damage caused by high temperatures during styling. They create a barrier between the hair and heat sources like flat irons, curling wands, and blow dryers. By using these products, individuals can help maintain their hair's health and prevent issues such as dryness, breakage, and split ends. Typically available in sprays, creams, or serums, heat protectants contain ingredients that help to lock in moisture and reduce frizz. To achieve the best results, it's important to apply the product evenly to damp or dry hair before using any heat styling tools.
