Use a high quality flat iron

Use a high quality flat iron with ceramic or tourmaline plates instead of metal plates. Ceramic and tourmaline materials produce far infrared heat and negative ions that lock in your hairs natural oils and moisture to prevent it from drying out. Ceramic and tourmaline flat irons are also better at combating frizz, and also give you much sleeker and smoother results than a metal flat iron. It is definitely worth it to spend more money on a quality flat iron that will not cause nearly as much damage.
