Too much stress from oxygen-related chemicals in your hair roots might damage the cells that give hair its color, leading to gray hair — especially when stuff like hydrogen peroxide builds up and harms those color-making cells.

As we age, damage from oxidative stress can harm the cells that give hair its color, especially because the body’s natural antioxidants weaken over time — this leads to grey hair.

As we age, our hair might turn gray because of a buildup of a natural chemical called hydrogen peroxide in the hair, and our body's ability to clean it up weakens — this messes with the pigment-making process in hair.

Going gray isn’t just about getting older — it’s because of damage from stress inside the hair roots, where too much hydrogen peroxide builds up and the body can’t fight it off anymore.

Your hair color comes from cells in your hair roots, and as you age, those cells slow down — that's why hair turns gray. But new research says things like stress might also play a role.

When your hair grows fast, it might stress the cells that give hair its color, causing them to wear out faster and turn hair gray sooner.
