In 1984 Mary Lou Retton tumbled into the hearts of America. So did her haircut. I remember very well getting my very own Mary Lou haircut that year. The wedge, or at least variations of Mary Lou's haircut, have never really gone out of style. Sure, the trends change, but we all remember how our Olympic star made the style famous! Twenty-four years later, I find myself wondering if any of our Olympic stars will spur a hair movement the way Mary Lou did.
