Demi Lovato has not only made a name for herself in the entertainment industry but the "Neon Lights" singer has become quite a hair trendsetter. The 21-year-old is famous for her always-changing tresses, which is currently in a lavender-silver ombré.

According to E! News, Wilmer Valderramma's girlfriend has experimented with colors ranging from bubble gum pink to teal-green ombré. The big question now is just how does the "Let It Go" artist settle on picking the perfect shade for her mane?

Well, Demi Lovato revealed her secret to picking the perfect color before her performance at the Pop-Tarts Crazy Good Summer free concert tour in her hometown Dallas, Texas.

She told E! News, "I love going on Pinterest and looking at different hair colors," adding, "Whenever I see like a cool color I sit with it for a little bit, and if it's really, really good then I'll get it."

Selena Gomez's on again, off again best friend also revealed what made her go for the lavender-silver look that eventually turned into a trend.

Lovato said, "I was kind of bored of the colors that I've had and I wanted something that wasn't as like out there as hot pink. So I changed it," adding, "I love lavender and I thought silver could be really cool, too."

As for her next drastic hair color change, the starlet admitted that she doesn't know just yet. "I'm not sure yet," adding, "I really want to do just a solid color; no ombré. But the second I do that I'm probably going to want the ombré back with some crazy color. Or the second I do that I'll want to go blond!"
