If you do nothing else with your hair this season, try a centre part. Here’s why: 1. A centre part changes the shape of your face and will have everyone asking if you did something different. 2. It’s free. 3. It was spotted at Balmain, Chanel, Valentino, Stella McCartney and Balenciaga—they would never steer you wrong. A perfect part requires a #flawless blowout. Bumble and Bumble Bb. All-Style Blow Dry ($ 37) is a serum- loaded balm that contains rose of Jericho to hydrate hair and prevent it from totally buggin’ out when the heat is on. Then bask in the glory of your new face.
