Another hair trick: How to do beachy waves in less than 5 minutes: Divide your hair into two parts. Twist each section and tie with a hair tie. Run your straighter/flat iron over both of the twist a few times. Untie twists, and you're done.
Start curling: Place the flat iron about of the way up the strand. Close the flat iron and twist it away from your face one time, then pull it slowly down the rest of the hair strand while it's still clamped shut. I love flat iron curling
