Blue rinse
A blue rinse is a dilute hair dye used to reduce the yellowed appearance of grey or white hair. The blue rinse gained popularity after Jean Harlow's appearance in the 1930 film Hell's Angels. Queen Elizabeth The Queen Mother also contributed to the popularity of the blue rinse in the 1940s, as well as East German leading politician Margot Honecker in the 1970s and 
1980s, who was considered a fashionable feminist trendsetter for many women in the Eastern Bloc. Politician Benjamin Netanyahu uses this style. In British politics, the term Blue Rinse Brigade has been used to refer to affluent older women involved in Conservative politics, charity work and committees. See also
