We never thought we'd see the day: Madelaine Petsch has said farewell to her iconic red hair color [2]. The Riverdale [3] star debuted her new look on Instagram on Oct. 13 and captioned it "Surprise I'm blonde now." Petsch's extra-long hair also got a massive chop in the photos and was styled in a tousled lob [4]. The transformation was part of a photo shoot with Wonderland magazine, in which an army of beauty pros, including celebrity hairstylist Sabrina Porsche [5], worked their magic.

Being a redhead is part of not only Petsch's identity, but her character Cheryl's [6] as well. Petsch previously told POPSUGAR, "My hair's naturally red [7], and if I ever dyed it, I think my mom would disown me. So I don't ever think about dyeing my hair." Chances are the platinum-blond hue [8] is a wig and only temporary, but we're still big fans of the change.

Take a look at Petsch's platinum blond hair color [9] ahead, and take a peek at the rest of the photo shoot [10] for more.
