The Psychology of Gray Hair
Abstract
Stress has long been associated with hair graying, yet there is little evidence to substantiate this claim. In a recent issue of Nature, Zhang et al. (2020) show that stress induces the release of noradrenaline from sympathetic nerves, which depletes the stem cells that give hair their color.
