Heat protectant sprays are hair care products designed to shield hair from damage caused by high temperatures during styling. They create a barrier that helps prevent moisture loss and reduce the risk of breakage when using tools like flat irons, curling wands, or blow dryers. These sprays typically contain ingredients that can withstand heat, such as silicones and natural oils. To use, simply apply the spray to dry or damp hair before styling. This helps maintain hair health and keeps it looking shiny and smooth, even after frequent heat exposure.
