Heat damage happens from using blow dryers, curling irons, and flat irons, so it’s incredibly important to use a heat protection product whenever you’re using these tools. People tend to turn the heat up to the maximum temperature when most people need to be using 280-325 degrees, not the 450 degree maximum a lot of these tools offer. You don’t bake your cupcakes at 450, so you don't necessarily need to be ironing your hair at 450 degrees.
