If there's one person who knows how to embrace their inner unicorn rainbow hair , it's Kylie Jenner. From bright red and mint green hues at New York Fashion Week to 'highlighter hair' and peach waist-length tones for Coachella , Kylie Jenner's hair is ever-changing. Meanwhile, her older sister, Kendall, sticks to a more muted palette of shoulder length hair that varies in dark tones, from chocolate brown to iconic, Kardashian, jet black. However, it might surprise you that the pair's hair is more alike than they'd have you believe. In an interview with ELLE , 19-year-old Kylie revealed exactly what her hair looks like under the myriad of colored wigs. "It's not a secret. I couldn't do on my hair. This is much easier\u2026" she said of her love of wigs, before Kendall joked: "She would have no hair otherwise." Later, Kylie explained: "You know, my hair is actually to my shoulders." Kendall added: "We have the same hair length. Nobody knows, but our hair is basically twinning. I should take a pic one day of us with our same hair so we look like sisters again."
