Demi Lovato Hair Transformations:

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."
