“After a decade of being a blonde, I finally crossed over to the dark side,” Kloss, 29, captioned the pictures and video, which show her flaunting her richly hued, newly brown locks while wearing a Michael Kors Collection coat, sweater and skirt. The mom of one’s darker ‘do was met with a slew of compliments from her followers. The Marvelous Mrs. Maisel’s Rachel Brosnahan, who is naturally blonde but currently has brunette hair like Kloss, commented with a fire emoji and told Kloss, “Welcome.” Singer Katy Perry also reacted to the model’s hair transformation by writing, “OMG ITS YOU.” Meanwhile, tennis star Serena Williams asked, “Wait what?????” According to Glamour, Kloss’ new hue is what color fanatics call “expensive brunette,” which celebrity hairstylist Tom Smith explained is “all about giving deeper hair energy, dimension and detail.” “It’s all too easy when going for a darker shade of hair color to apply one tone all over, a similar result to using a box dye at home,” he told the magazine. “I’m of the opinion that it’s professional hair colorists’ responsibility to give our clients something they could never get at home, and so expensive brunette is all about adding detail and interest with multiple deeper shades to make the result more dimensional and expensive-looking.” Smith pointed out that “in the celebrity world, it’s often ‘the bolder the better’… hence why so many celebrities are blonde or choose obviously artificial shades for their own hair or use wigs.” He added, “Now that a brunette can look equally as ‘expensive’ and ‘designed’ as brighter or bolder shades, it makes sense that many celebrities are interested in the deeper tones.” The major transformation isn’t Kloss’ first time turning heads thanks to a new head of hair—but she does seem to be the rare model who actually picks one look and sticks to it. In fact, back in 2014, when she debuted a jaw-droppingly-gorgeous platinum ‘do at the opening of Mario Testino’s MATE exhibition, it was reportedly the first time she’d ever colored her hair. “Celebrating the opening of a new exhibit last night at #MATE with the king of Peru, Mr. @mariotestino  Ps….notice anything different with my hair?,” the Kode with Klossy founder wrote alongside a snapshot from the event. The following day, the former Victoria’s Secret Angel shared a throwback photo of herself as child on her dad’s shoulders writing, “#tbt to the last time I was a blonde ;)…. p.s. I [heart] you dad.” Alexis Unno, the colorist who was responsible for Kloss’ lighter locks back then, told Allure that it was a “big milestone” for Kloss. “It’s the first time she’s colored her hair,” Unno shared. “She’s played around with clear glazes in the past, but other than that, she’s never actually dyed her hair.” Unno also noted that Kloss did not make the change to resemble her pal Taylor Swift, as many fans at the time assumed. “It wasn’t for a job or anything like that, and it wasn’t to look more like Taylor Swift, which is funny because everyone is saying that!” Unno said. “It was more of a personal thing—she was just in the mood for a change.” Next, Sporty Styles: Hair That Goes From Game to Glam
