Shirley Polykoff is the adwoman who first asked that question, then followed it up with an equally provocative suggestion that blondes have more ""fun"" in a campaign to convert the hair color of several generations of American women. Since she's a pre-Lib career woman, however, her autobiography is just as much about her wonderful immigrant parents, loving husband, and spunky little girls as it is about her achievements on Madison Avenue. Polykoff remembers her childhood attempt to assimilate by mimicking the styles in the magazines, later, she saw herself as a do-gooder, performing a public service for American womanhood as well as for Clairol and Foote, Cone & Belding. She admits, ""I guess I believe all those schmaltzy things I say in the ads. . ."" and attributes her success to the fact that ""what appeals to me appeals to the lady in Dubuque, or Fresno, or Mobile. . . ."" if they're sitting under the dryer.
