Abstract in brief
Hair greying is a sign of aging caused by the loss of pigment in hair shafts, which involves various processes like melanocyte stem cell damage and death.
Oxidative stress, which results from reactive oxygen species (ROS), plays a central role by damaging cells in the hair follicle, especially when antioxidant defenses like BCL2 and catalase decrease with age.
Understanding why certain melanocytes survive longer than others and how oxidative damage affects them could lead to new treatments to prevent or even reverse hair greying.]
