Hydrogen peroxide is a natural oxidant; we produce an enzyme called catalase that breaks down hydrogen peroxide turning it into water and oxygen. As catalase function decreases, the levels of hydrogen peroxide increase. High levels of hydrogen peroxide block the production of pigment, leading to gray hair.
