If the flat iron or blow dryer is your best friend, you might want to take a break from each other. Excessive heat can dry out the hair, causing damage and making it look dull. If you absolutely can’t live without those super straight locks or luscious curls, try lowering the heat on your styling tool. If you’re used to blow-drying your hair every day, wait until it’s about 70% air-dried first, and try to maintain a distance so you’re not blasting your hair with too much heat. Finally, be sure to apply a heat protector on your hair before you start styling!
