Gray Hair and Hydrogen Peroxide
We all know that graying of hair is a largely inherited trait; that if one or the other of your parents started to gray early, chances are so will you. There are of course contributory factors that influence graying of hair, such as the environment, pollution, nutrition etc as well.
And now researchers have found that too much hydrogen peroxide may also be one of the factors that cause hair to go gray. Hydrogen peroxide, which is produced naturally in the human body, interferes with melanin, the pigment that colors our hair and skin.
The study found that as we age, an enzyme responsible for breaking down hydrogen peroxide, catalase, slows down. As the hydrogen peroxide builds up, our hair turns gray or white
“All of our hair cells make a tiny bit of hydrogen peroxide, but as we get older, this little bit becomes a lot. We bleach our hair pigment from within, and our hair turns gray and then white. This research, however, is an important first step to get at the root of the problem, so to speak” writes Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal.
“This new insight could open new strategies for intervention and reversal of the hair graying process,” wrote John Wood, lead author of the study.
