What causes graying?Updated 20 days ago

The same factors that contribute to premature aging can also contribute to early graying. Excess oxidative stress can overwhelm the follicle’s natural antioxidant defenses, reducing pigment production (melanogenesis). As pigment production declines, the hair gradually loses color and appears gray. Oxidative stress may also affect other cells within the follicle, further contributing to changes in hair quality over time.
