It seems like just when her fans get used to her latest hair look Rihanna makes yet another dramatic change.

The "We Found Love" singer, who turns 24 on Monday, loves to experiment with her 'do and the result impacts more than her appearance.

"When I cut my hair, the whole sound changed, my style changed," she told Vogue magazine of chopping her hair into an edgy bob back in 2008.

And since then, she's done everything from shave the sides to dyeing it platinum blonde.

"I can't think of a shade she won't try," says celebrity stylist Ursula Stephen, who cuts and colors the singer's hair.
