How to Prevent and Reverse Gray Hair

Squelch the Stress

"New research suggests that depigmentation, or graying, of hair is triggered by stress—and likely inflammation from stress," says Julie Upton, M.S., RD, co-founder of the nutrition news company Appetite for Health in San Francisco. A 2020 study in the International Journal of Trichology found that oxidative stress (an imbalance of antioxidants and free radicals in the body that can trigger cell and tissue damage and accelerated aging) is linked to premature graying.
