Halsey's Updo on Jimmy Fallon Is Giving Major Pamela Anderson Vibes

Halsey brought the heat on "The Tonight Show Starring Jimmy Fallon" last night, rocking Pamela Anderson's signature messy updo. The style, which shot to the forefront of pop culture by Hulu's "Pam and Tommy," was a staple of '90s beauty, and now as Y2K trends continue to dominate, it's no surprise that we're seeing it make a reappearance.

Halsey's specific take featured tousled blond beach waves piled on top of their head and a few strategic strands left out to frame the face. Other celebrities who have tried the iconic hairstyle include Selena Gomez and Kim Kardashian, who tested the updo while visiting Italy for her sister Kourtney Kardashian's wedding.

As celebrity hairstylist Clayton Hawkins previously told POPSUGAR, this is only the beginning of the resurgence of Anderson's beauty looks. "Her classic messy bun is gonna be everywhere this summer," he said. "Everyone is obsessed with Pamela Anderson's fierce '90s beauty these days, and for good reason — it's iconic."

But 1990s beauty goes way beyond hair, which means you can expect to see all kinds of nostalgic trends on the rise in the weeks to come. Think Drew Barrymore's brown lipstick, Cameron Diaz's blue eyeshadow, and J Lo's icy gloss. Ahead, check out Halsey's '90s hairstyle from every angle.
