Leighton Meester’s New Hair Could Be the Most Drastic Change We’ve Seen Yet

Leighton Meester has been faithfully rocking her signature brunette locks long before we ever met Blair Waldorf. The 31-year-old actress has added a few light-catching highlights here and there throughout the years, but her coffee-colored coif was always in close by. Her latest update, however, is one for the books.

“I’m having a blonde moment,” Meester shares with her latest Instagram post, capturing her new platinum-blond strands and fresh new lob. “I like to try different things and experiment. So when I wanted to change my hair, I just thought, ‘I should just completely go for it,’” she tells PeopleStyle.

With Jayne Mansfield as the inspiration behind the change, Meester gave fans a sneak peek of her new icy locks on her Instagram story. But when it officially came time for the big reveal, the internet went haywire. In just one hour, her selfie racked up more than 300,000 likes and almost 8,000 comments from heart-eyed followers.

As for how her strands can survive such a drastic change (and a significant amount of bleach), it could have something to do with her go-to hair regimen, which consists of using the Nexxus Keraphix Masque for Damaged Hair ($16), "as much as possible," along with the the Nexxus Keraphix Reconstructing Protein Treatment ($16) once a week, too (she's a brand ambassador). "It’s really important for me for my hair to feel as healthy as it looks.” I don't know about you, but her transformation is giving this brunette some serious hair envy.
