The quest to look younger can be a tricky little battle. But maybe it’s all in your head—literally. New longevity research proves that making an age-related change (say, dying your gray hair bleach-blonde) can trick you into feeling younger, and other people pick up on that feeling itself! In one study, women aged 27 to 83 were asked if they felt younger after a hair appointment, regardless of what they had done to their hair. The amazing findings: The women who reported feeling younger were rated as looking younger to independent raters, even when their hair was cropped out of the picture. Quite the spin on the old look good/feel good maxim, eh? Now it’s feel young, look young!
