During her younger years, Kaia Gerber was well-known for her likeness to her supermodel mother, Cindy Crawford. Following her 18th birthday in 2019, however, the runway regular snipped off her hair into a very short bob, seeming to send her popularity skyrocketing even further.
Australian model (and former architecture student) Fernanda Ly had her big break at Louis Vuitton's spring/summer '15 show, and her instantly-recognisable pink hair helped her become one of the most in-demand models of following seasons. Though she's now switched her hair to blonde (pictured, right), we'll never forget the pink 'do that helped make her famous.
Though the Australian model enjoyed success while her hair was a darker brunette hue in the early days of her career, it was the decision to go peroxide blonde that made Lee a household name. Nowadays her hair flits between different shades of blonde.
Okay, okay, she's wearing a wig on the left. But it's good to get perspective of what Bella would look like if she reverted back to her naturally blonde waves. She dyed them brunette at a young age, and the dye job helped her carve a separate path to blonde bombshell sister Gigi.
This British beauty basically rose to fame overnight after chopping her waist-length waves into a cool-girl shaggy bob. She has since modelled for the likes of Chanel, Burberry, Hermès and Saint Laurent.
Quite the opposite to Jessica Stam, Karen Elson found fame when she swapped her natural blonde for her now-signature red. Legend has it Steven Meisel gave her an ultimatum when he shot her back in '98: dye your hair black or red. The rest, as they say, is history.
Supermodel Linda Evangelista's haircut by Julien d'Y is now a relic of fashion history. Namely because the whole process was snapped by Peter Lindbergh, including the moment Linda started crying straight afterwards. It goes without saying that the chop paid off.
Ruth Bell and her identical twin sister May began their modelling careers with hip-skimming red locks. Perhaps wanting to differentiate herself from her sister, Ruth shaved her head into a buzzcut, and has since become one of the most in-demand models in the world, fronting campaigns for Dior and Burberry.
