Heat protectants are hair care products designed to shield hair from damage caused by heat styling tools like flat irons, curling wands, and blow dryers. They typically contain ingredients that form a barrier on the hair, reducing moisture loss and preventing breakage. Using a heat protectant can help maintain the hair's health and shine, making it an essential step in any heat styling routine. To use a heat protectant, spray or apply it evenly to damp or dry hair before styling. It's important to choose a product suitable for your hair type, as some formulas are designed for fine hair while others work better for thick or curly hair. Regular use of heat protectants can lead to healthier, more resilient hair over time.
