Heat protectant is a hair care product designed to shield hair from damage caused by heat styling tools like flat irons, curling wands, and blow dryers. These products typically contain ingredients that form a barrier around the hair, helping to prevent moisture loss and reduce the risk of breakage and split ends. Using a heat protectant is essential for maintaining healthy hair, especially for those who frequently style their hair with heat. Applying it before using any heat tool can help keep hair looking shiny and vibrant while minimizing the long-term effects of heat exposure.
