Demi Lovato
Demi Lovato dyed the tips of her hair purple and silvery-blue in June 2014. Back in April she changed her hair from pink to a shade of dark brown close to her natural color, but she quickly grew bored. “I know I said I was gonna give my hair a break but.. I #REALLYDONTCARE,” she tweeted. She kept the existing brown down to her chin and added the new colors at the bottom with an ombré effect.
