This study investigates the influence of hair colour, in particular blonde hair, on women’s own wages
and also their spouse’s wages using a large U.S. data set.
Regression results indicate that blonde women receive a wage premium equivalent in size to the return for an extra year of schooling.
A significant blondeness effect is also evident in the marriage market. Blonde women are no more or less likely to be married; but, their spouse’s wages are around six percent higher than the wages of other spouse’s.
