Hair is always a project for people to deal with, especially if you always cut, dye, or style it in different ways every few weeks. For Demi Lovato, it's more like a hobby.

The 21-year-old actress and singer has changed her hair to every color in the visible spectrum. She currently has a lavender/silver ombré going on. An ombré is a hair trend which features darker and natural hues at the roots with dyed lightening toward the ends.

According to E! News, the “Heart Attack” singer decides her hair color by doing something we all do every day: browsing the Internet.

"I love going on Pinterest and looking at different hair colors," Lovato told E! News. "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."

Fellow Disney-alum Raven-Symoné has also adopted the trend, though it’s not certain if she’s drawing inspiration from Lovato. Lovato says she chose these colors because she wanted something less eye-popping.

"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," Lovato said. "I love lavender and I thought silver could be really cool, too."

Already gone through many colors, Lovato isn’t sure what she’s going to choose next.

"I'm not sure yet," she tells us. "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!"
