Shirley Polykoff (January 18, 1908 – June 4, 1998) was an American advertising executive whose "Does She... Or Doesn't She?" tagline for Clairol dramatically increased sales and earned her a place in the Advertising Hall of Fame.[1]
Born in Brooklyn, she started her career in magazine and retail ad sales before taking a position at Foote, Cone & Belding. In 1955 she took over the Clairol account, and her line helped take the hair color category from $25 million to $200 million annually, with Clairol holding a 50% market share.
She was #24 on the Advertising Age 100 people of the 20th century and is very likely the model for the character Peggy Olsen in Mad Men.
