From a ponytail to wearing her hair completely down, Ariana tested out a few relatively unexpected looks, along with her signature half-up-half-down 'do, throughout the past few days. Most recently, she sported a braided accent at the 106.1 KISS FM Jingle Ball in Dallas on Monday (third photo).
The way she's wearing her hair isn't the only big beauty change for the star: She's going blonder, too!
