Organic Biotin Vitamins - Gray Hair Solution for Men and Women - Grey Hair Care - Catalase 5000 - Anti Gray Hair Formula - Folic Acid, Biotin, Horsetail, Nettle root, Saw Palmetto - 3B 180 Capsules Catalase Catalase is an enzyme and a lack of it is involved in hair turning gray. As we get older, we make less catalase. In other words, lack of catalase causes the buildup of hydrogen peroxide, which in turn “bleaches” the hair and skin by blocking the production of the pigments that give skin and hair its color. Adding catalase can aid in helping to prevent discoloration. Folic Acid and Gray HairFolic acid is essential for many bodily processes. A deficiency of this vitamin may not only slow your hair's growth, but it can also cause your strands to turn gray. While gray hair that occurs with age or genetics cannot be reversed, hair that is gray because of this vitamin deficiency typically returns to its normal color once you increase your folic acid levels.
