On damp, clean hair, apply L'Oréal Paris Advanced Hairstyle Boost It Blow Out Heat Spray ($5) and comb through, then flip your head over and blow-dry, focusing on the roots. Once they are completely dry, flip your hair back and use a round brush to finish your blowout. This is when you should part your strands — try a deep side part like Blake's for a retro-glam look.
After you've finished your blowout, use a one- to two-inch barreled curling iron and wrap inch-wide sections around it to create loose waves. Clip up each curl to help it set faster, and spray on L'Oréal Paris Advanced Hairstyle Lock It Fine Control Hair Spray ($5) to strengthen the coil's hold.
Once your hair has cooled, brush out the curls with a paddle brush for a more casual, moveable style. Tuck your hair behind your ear (like Blake!) and finish with L'Oréal Paris Elnett Satin Hair Spray ($15).
