The Evolution of Demi Lovato

Demi Lovato has always been quite outspoken about the fact that she's a work in progress (you know, like the rest of us), and her evolution as a singer, songwriter, actress, mental health spokeswoman and — most of all — as a person — has been incredibly inspiring to watch.

Accordingly, the "Stone Cold" singer's shift in sound over the years has lent itself to a rapid shift in style over the years, moving from her rock-pop roots to sleek uptempo club cuts to soul-baring ballads that chill to the bone. (Like a skyscraper!) From Don't Forget all the way up to Confident, she's supplied plenty of different fashionable looks along the way, and her well-conditioned locks (and Devonne by Demi-prepped skin) have seen a whole bunch of shades, lengths and style switch-ups. She's gone red! She's gone blue! Pink tips! You name it — she's done it...and buzzed half of it off, too.

But then again, she's got the ultimate accessory to rock any look: Confidence. And hey, what's wrong with being confident?

Check out how far Demi's come, from her girl-next-door swept bang days of 2008 to her slicked-back, sexy "Cool For The Summer" styling. Go ahead — figure out the next move for your 'do!
