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.

Scientists think that when there’s too much damage from natural body chemicals (oxidative stress) and not enough protection from helpful antioxidants, it might cause hair to turn gray earlier than normal.

Some people get gray hair early because of things like their genes, stress in their body, smoking, or not having enough of certain vitamins and minerals like iron or copper.

Going gray might happen because the stem cells that keep your hair colored aren't working properly as you age.

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.
