26 New Beauty Products Our Editors Are Loving This September

Bumble and bumble Seaweed Oil Control Styling Primer ($36)

"You know a product is good when it can hold up to even the most sweltering of summer days — when temperatures hit 96 degrees with 80 percent humidity, you know the kind — which is the real-life scenario I found myself in when trying Bumble and Bumble's newest priming spray. I wanted to see how the spray would hold up against humidity, so I spritzed it on my damp hair liberally before blow-drying and then venturing outside. No hairspray, no anti-frizz cream, nothing. Three days later and I can confirm: my fine, frizz-prone, wavy hair had nary a flyaway in sight. It's been in my hair-care rotation ever since." — Kelsey Castañon, Editor-in-Chief
