Good news for all you millennials. Your junior high flatiron skills are about to come in handy. “Long, sleek hair with a middle part is making a big comeback and has been seen everywhere from celebrities to the runways,” says celebrity colorist and stylist Meri Kate O'Connor. You've definitely seen the look on Dua Lipa, Kim Kardashian, Kasey Musgraves, and, of course, Cardi B above. For this ultimate sleek style, prep work is key. Work a frizz-fighting leave-in, like BRIOGEO HAIR CARE Farewell Frizz™ Rosarco Milk Leave-In Conditioner, through your damp hair before you blow-dry.

O'Connor and celebrity stylist Justine Marjan agree that rich brunette hair color is about to have a big moment. Warmer, richer hues (like Mandy Moore's above) make hair look instantly healthier and shinier. “If your hair is dark, ask for a rich chocolate brown,” says Marjan. “If it's lighter, try an auburn or chestnut shade. Not only will this help hair to restore vibrancy, but it helps to bring some warmth to the skin, too.”

Time to grab your round brushes and blow dryers (or at least your blow-dry brushes) because the '90s-era bouncy blowout is back in a major way. You've probably seen this trend all over your Instagram feed already, and it's only getting more popular. Ask your stylist for long layers throughout and a few face-framing pieces near the front. The more movement in your cut, the better this style will look. Pro trick: Air dry your hair as much as possible before going in with a blow dryer to cut down on dry time and heat exposure.
