Eponymous hairstyle
An eponymous hairstyle is a particular hairstyle that has become fashionable during a certain period of time through its association with a prominent individual.
Women
The "wannabe" effect
Imitation of such styles can sometimes be attributed to what became known in the 1980s as the "wannabe" effect, a term used particularly with reference to young women who wished to emulate (i.e. "wanna be" like) the American singer Madonna. A 2010 study of British women found that half took a copy of a celebrity's photograph to their salons to obtain a similar hairstyle.
The quest for a particular eponymous style was caricatured in Plum Sykes' novel Bergdorf Blondes (2004), in which it was rumoured that glamorous New York heiress Julie Bergdorf had her blonde hair touched up every 13 days ("$450 a highlight") by a stylist at her family's store, Bergdorf Goodman. Thus, other "Thirteen Day Blondes" who attained Julie's precise colour—likened to that of the "very white" hair of Carolyn Bessette-Kennedy—became known as "Bergdorf Blondes."
