Selena Gomez declared she made "a subtle change" to her hair [2] when she posted a photo rocking a high ponytail with a sneaky undercut. It looks like that style was over in a hot second, because the 25-year-old star was spotted, a few days later, with her short hair again. A fan posted a photo with her on Instagram where she was back to her shorter hair [3].
At the 2017 American Music Awards, Selena stunned fans when she showed up with a dirty-blond lob [4], which took nine hours and eight bowls of bleach [5] to complete. After all that, it didn't last, because just one month later, she was back to brunette [6]. Throughout her career, Selena has sported many different hairstyles [7], and each of them has worked wonders for her.
