Found a few gray streaks? Study reveals your gray hair might actually be good for you
A new study from the University of Tokyo suggests gray hair might be a natural defense against skin cancer. Researchers found that when pigment stem cells experience severe DNA damage, they shut down to prevent potential cancerous growths, leading to graying. This reframes graying as a protective mechanism rather than just a sign of aging.
