This One Hair Trend Made Serious Waves on the Oscars Red Carpet

Stars on the Oscars red carpet always bring their A-game, but one major trend seems to show up over and over again is waves. (And in virtually every iteration of the style, no less.) From retro to voluminous and romantic to borderline disco, there didn't seem to be one decade missing at the 2018 awards ceremony. And after seeing so many sleek and straight looks lately, we couldn't help but rejoice.

Mastering a fusion between classic and modern, we're in love with the way Gerwig's super-fresh chop pairs with romantic waves, which came courtesy of TresemmГ© stylist John Dahlstrom. In fact, it's almost giving us modern-day flapper vibes. To create the look, Dahlstrom added mousse to Gerwig's clean, towel-dried hair before combing through, creating a side part, and then scrunching and drying the hair with Dyson's Supersonic Hair Dryer ($399) and diffuser. To finish, he used a comb to create the subtle finger wave pattern, used small clips to secure, continued to dry the hair, and then sprayed with TresemmГ©'s Compressed Micro-Mist Hair Spray Level 2: Smooth ($5). Once the clips were removed-voilГ !

Get Out's Betty Gabriel epitomizes the ultimate half updo style: bold waves, dramatic volume up top, and cheekbone-highlighting height.

Jennifer Lawrence is never afraid to make a statement, and her maximal California-inspired waves did just that on this red carpet. Paired with her shimmering and metallic Dior gown, she kind of looked like an actual Oscar. And we mean that in the best way possible.

Can Salma Hayek do any wrong? (No, the answer is no.) Thus, another Oscars red carpet, another covetable hair look. And though she opted for a low and windswept updo, we can't help but admire the soft wisps and tendrils that clue us in on her natural waves for a classically effortless look.

According to Moroccanoil celebrity hairstylist Bryce Scarlett, Margot Robbie's demure waves were inspired entirely by her showstopping Chanel couture gown. "Her dress was extremely feminine and elegant, and we wanted to take the length of her hair up to make sure that it felt very classic and modern to go with her gorgeous dress," he said.

To get the look yourself, Scarlett says to use a dime-size amount of Moroccanoil's famed Treatment Light Hair Oil ($34) followed by the brand's Smoothing Lotion ($32) on mid-lengths through the ends. Next, blow out the hair and create a deep side part for some added drama. To finish, section hair off into one-inch pieces and use a flat iron to create bend by moving the tool "into the hair, out, and then in again" to create that ultimate S wave.

Demonstrating that waves are most definitely a thing even if you have a closer crop, Mary J. Blige epitomized the wave trend at this Oscars ceremony. A platinum-blonde pompadour? So good.

Last, but certainly not least, Allison Williams's Oscar's hairstyle gave us all the vintage feels with her glamourous Old Hollywood waves. Plus, with her Giorgio Armani dress and a glistening earful of Harry Winston diamonds, well, let's just say that we think Marilyn would be proud.

To create the look, celebrity hairstylist, Peter LuxВ began by sprayingВ Goldwell's New Kerasilk Style Forming ShapeВ Spray ($27)В onto Williams towel-dried hair. Then, he styled the actress's hair with the VarisВ HairВ Dryer ($225)В and Nylon BrushВ ($22)В to create a smooth and shinyВ texture. To finish, he curled small sections of Williams' hair in a strategic forward motion to ensure ultimate movement, body, and glamorous shine.
