Jason Lee teaches us how to style your hair with Blake Lively waves in this tutorial. Start off with clean straight hair, then heat up your curling iron. After this, grab a section of hair on the top of the head and place the middle of the strands into the curling iron, wrapping it around. After a few seconds, let the hair go and comb through it with your fingers when it drops down. Continue do this through the entire head until you have all the hair curled. When finished, apply hair spray to help the curls stay and tease the hair if you want more volume.
