Question: I’ve read that an enzyme supplement called catalase helps reverse hair graying. I think this sounds too good to be true. But, I hope I’m wrong! What’s your opinion about these products?

Answer: For starters, let’s briefly review what causes the graying of hair and the potential role of catalase. The loss of melanin, a pigment which colors hair, is partially induced by a build up or overproduction of hydrogen peroxide in hair follicles. Catalase, an antioxidant enzyme produced by the body, helps convert hydrogen peroxide into two, non-bleaching substances – oxygen and water. This is the rationale for some of the supplements you’ve likely seen. However, it should be noted that there are other enzymes (MSR A and B) which also affect melanin production and tend to decline with age. For this reason, L’Oreal, the cosmetic giant, is currently developing a supposedly all-natural supplement which targets yet another hair graying mechanism – tyrosine-related protein TRP-2 production.
