Celebrities love slicking their hair back on the red carpet, and as long as you have the right products, you can pull the stunning look off in real life, too. The trick is to not slop a bunch of gel into your hair. Start off by blow drying your hair back, away from your face. Once that's done, douse all of your hair with mousse, concentrating most the product from the hairline to the mid-lengths. Let it air dry (or dry it gently with a diffuser attachment) and top it all off with hair oil or shine spray to give it that high-gloss, reflective finish.
