The Super Bowl commercials are starting to hit the Web, and drugstore shampoo brand Sunsilk has just debuted its ad. It features Marilyn Monroe, Shakira, and Madonna, and the idea is that "Life Can't Wait." As a shampoo commercial, it's a little perplexing. Are we to believe that good hair is the impetus for their success? Don't get me wrong, a great cut and color can do wonders, but I hardly think Madonna became an international superstar because of her hair.
