THE SECRET: In a regular braid there are 3 strands. For this look, all you do is braid one of those strands beforehand and loosen it up with your fingers, then braid as usual. This creates extra texture + breaks up the mundane pattern of a regular braid.
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
