Hairstyle File: Rihanna's Ever-Evolving 'Do!

Rihanna is many things; she's one of the most glamorous international pop stars in the world; she's a perfumista (we're loving Reb'l Fleur); and ever since she went fire engine red, she's become a bonafide coif chameleon. 

We first spotted her short crimson crop in June 2010, and in a year she tried on every style under the sun -- from Annie ringlets to Lady Miss Kier bouffants. And this fall, her fiery hue evolved into a streaked golden-brown shade enhanced by luscious, fat curls. Love!

Here, we let's look at the evolution of the pop princess' trendsetting tresses.
