 In the 1950s, just 7% of American women used hair color (or admitted to doing so), at a time when the common belief was that only actresses, models and other women considered promiscuous altered their natural shade.To help change that attitude, Clairol eschewed celebrities in favor of the average woman for its Miss Clairol and Nice ’n Easy hair color campaigns.The idea to buck the trend of that era’s advertising style — which emphasized high glamour rather than girl-next-door vignettes — was the brainchild of lead copywriter Shirley Polykoff, whose work on the Clairol hair color campaign was a career high point.
