Jessica Alba – 38

Jessica Alba’s career in acting began when she was just 13 years old and it was with her performing on The Secret World. We don’t blame you for not having picked her out because she was wearing her hair in its natural brunette color. With time, she gradually changed her style, beginning with a couple of layers and eventually a bit of color until she became bolder with her ‘do. Now, she embraces highlights like she’s been doing it all her life! Alba is fortunate that she can bounce between the brunette and blonde and all in between without a problem – it all suits her!
