Senile graying of human hair has been the subject of intense research since ancient times. Hydrogen peroxide attacks the enzyme tyrosinase by oxidizing an amino acid, methionine, at the active site. With increasing age, the quantity builds up, because the human body can no longer keep up neutralizing the hydrogen peroxide using the enzyme catalyse, which breaks down hydrogen peroxide into its two components water and oxygen. 466 people like this. from Stiefel International, and by private donations.
