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.

When the energy factories inside hair follicles don't work right, they make too many harmful molecules that damage the color-producing cells, making hair turn gray faster.

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.

When too much hydrogen peroxide builds up in your hair follicles, it stops the pigment-making enzyme from working, which is why hair turns gray over time.

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.
