Gather all materials needed and plug in flat iron. Give flat iron enough time to reach the desired temperature. Make sure to use a safe outlet and place on a flat, sturdy surface, away from water.
If hair is wet, plug in blow dryer and dry hair until there are no damp spots. Brushing hair while blow drying is recommended to untangle hair and help hair dry faster. You may also brush hair after blow drying to untangle hair.
Optional: If you use heat protecting serum, place a quarter size amount (unless product specifies otherwise) of the serum in the palm of your hand and apply to hair working from root to tip. This will help fight heat damage to the hair.
