Revealing the cover of her new single Focus, Ariana sparked a social media frenzy when she debuted the new colour.
Recently, there appears to be a trend in Hollywood for changing hair colour. And perhaps the biggest experimenter is Kylie Jenner, who has shown off nearly all the colours of the rainbow in recent years.

And the 18-year-old recently revealed why she undergoes hair makeovers so frequently.
The Keeping up with the Kardashians star confessed that she has an "addiction" to trying new looks because they make her "feel like a new person".
"I first dyed my hair when I was 16," she confessed in a post on her app. "I dyed it blue and I never even asked my mom. After that, I've just had this addiction to changing my hair. It makes me feel like a new person. I love feeling different and I love leaving the house knowing that nobody has ever seen me this way."

From long bright green hair to shoulder-length turquoise locks or blonde waves, every one of Kylie's makeovers has been equally as show-stopping as the one before, and the reality TV star admitted that she doesn't see the point in repeating a look.
"It's hard for me to go back to different styles I've worn before; I don't always like my normal short, black hair," she revealed. "That look makes me feel like I'm going back in time. It's like I'm going back to that moment a year ago and I just don't want to be in that space."
