This One Hair Trend Made Serious Waves on the 2018 Oscars Red Carpet

This year's Oscars red carpet truly brought its A game, but one major trend seemed to show up over and over again: 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. And after seeing so many sleek and straight looks within the last year, we couldn't help but rejoice.

While Jennifer Lawrence brought California flavor to the wave trend, Betty Gabriel and Salma Hayek went a bit softer and more medieval. Then Greta Gerwig and Allison Williams veered vintage with iconic glamour: undulating finger waves (Gerwig) and Veronica Lake–inspired strands (Williams).
