In the 1960s Vidal Sassoon revolutionized the hair industry by inventing haircuts that were considered "wash and wear". Before this women spent hours in the salon getting their hair washed and set weekly. A "Coupe Sixty-One", (though spelled differently from the original) is a haircut and style created by a Dutch hairstylist depicting the wash and wear phenomenon.
