Rihanna changes her radiant red hair often, thanks to her superstar hairstylist Ursula Stephen. So far, Stephen twisted Rihanna’s locks into corkscrew curls, a russet bob, straight and striking strands, and on Sunday, she returned the pop star to her tightly-cropped pixie for her Academy of Country Music Awards performance. “We haven't done a bob in a while, but the idea to go short was Rihanna’s,” Stephen told InStyle. “She texted me a couple days prior to the ACM Awards and said she wanted to do something short. She missed her face, and I did too!” As for her hair attitude? “We’re not committed to anything but having fun!” Click through to see all of Rihanna’s redhead hairstyles, and for more expert hair tips, pick up the new InStyle Hair issue, on newsstands Friday.
