"Then divide your mane into three sections: top, sides and back leaving the nape area free," he says. "Take small sections, starting at the nape, and blow-dry (using a nozzle attachment) with a large round brush. When hair is completely dry, take large sections and wrap three-quarters of it around your brush. With the nozzle blow hot air for about 10 seconds then hit the cool button to give that section a blast of cold air. Carefully release the section from the brush and continue until you have completed the whole head."INSIDER TRICK "After rinsing your hair completely, follow with a final cool water rinse for when you want extra volume. This seals the cuticle and helps hair radiate extra shine," says Babaii.

Then apply black mascara, nude lip liner and pink gloss.INSIDER TRICK "I do the eyes first, then foundation, cover-up and powder," says Shaw. "This saves time by not having to lean under the eyes multipe times and reapply makeup. Then I do cheeks, brows and lips last."
