Scarlett Johansson Has White Hair

Is being blond the secret to their success?

Have you ever noticed the more famous a woman gets in Hollywood, the blonder her hair seems to become? Coincidence? We think not. There must be some movie magic in all that peroxide.

Take a look at these top box-office blondies.

Scarlett Johansson was a full-on brunette when she entered the biz, but the bleach has paid off. Now she's not only a muse to Woody Allen, but also the wife of hottie Ryan Reynolds.

Nicole Kidman first came onto the scene as a ginger-haired Aussie. She's now the white blond wife of country star Keith Urban.

Madonna took a cue from another famous blonde, Marilyn Monroe, and turned her dark locks (and her career) platinum.

Kate Winslet went down with the Titanic as a redhead. Her career re-emerged more shiny and bright, as did her hair.

Britney Spears was just a sweet thing from Louisiana, until she met K-Fed, had two kids, and shaved her head. Now she's making a comeback, and as her hair grows longer, it gets lighter and lighter.
