The slogan "Does she...or doesn't she?" was created to promote which American company?

Clairol is an American personal care-product division of the company Coty, specializing in hair coloring and hair care.

Clairol's one-step home hair color was a breakthrough in the beauty industry, as was its advertising campaign. Clairol hired the advertising firm Foote, Cone & Belding, which assigned the account to a junior copywriter (Shirley Polykoff, the only female copywriter at the firm). Polykoff's future mother-in-law inspired the "Does she...or doesn't she?" slogan. After meeting Polykoff for the first time, she took her son aside and asked him about the true color of his girlfriend's hair. "Does she color her hair, or doesn't she?" the embarrassed Polykoff could imagine her mother-in-law-to-be asking. Although Polykoff did color her hair, the practice was not something to which women openly admitted.

To counter the stigma of hair color and create a wholesome, sentimental image for Clairol, early print ads—some of which were shot by fashion photographers Richard Avedon and Irving Penn—featured girl-next-door models accompanied by children with hair the same color. "Does she...or doesn't she?" became an effective slogan; within six years, 70% of all adult women were coloring their hair, and Clairol's sales increased fourfold. In 1967, Polykoff was inducted into the Advertising Hall of Fame.
