"We find that attractive individuals earn roughly 20 percent more than people of average attractiveness,
but this gap is reduced when controlling for grooming, suggesting that the beauty premium can be actively cultivated. Further, while both conventional wisdom and previous research suggest the importance of attractiveness might vary by gender, we find no gender differences in the attractiveness gradient. However, we do find that grooming accounts for the entire attractiveness premium for women, and only half of the premium for men."
