What Is a Heat Protectant
A heat protectant is a product designed to reduce moisture loss and protein damage caused by hot tools. It works by forming a barrier that helps distribute heat more evenly across the hair shaft.
Should You Apply It Before Blow Drying
Yes, applying heat protectant before blow drying is recommended whenever you use direct heat on damp or dry hair. It helps limit dehydration and surface damage, especially when using a dryer on medium or high settings. According to the American Academy of Dermatology, protecting hair from repeated heat exposure can help maintain its strength and texture over time. Learn more about protecting hair from heat.
How to Use It Correctly
Apply a small amount evenly to towel-dried hair before styling. Focus on mid-lengths and ends, where damage is most common. Avoid overloading the hair, and always follow the product instructions for best results.
