Demi Lovato dyes her hair silver and purple ahead of world tour

Demi Lovato has once again changed up her mane.
The 21-year-old singer took to Instagram Wednesday to share a few photos her new purple and silver hair.
"Lavender/ silver ombre... I know I said I was gonna give my hair a break but... I #REALLYDONTCARE," the "Neon Lights" singer captioned one of the images.
Lovato's new hair color comes as no surprise as the singer often experiments with different colors and styles. The former Disney star has previously dyed her hair red, blue, pink and blonde and she even shaved part of her head in March.
The singer's new hairstyle comes a week after she unveiled the North American dates for Demi: The World Tour. Tickets for the tour will go on sale June 6.
