Why Hair Goes Gray

I often wondered why hair starts turning gray very early in life for some people, and yet for others, this process begins slowly much later in life.

So, when I found this article with some scientific explanations, I wanted to share it with all of you, so you also stop wondering and blaming other factors for turning your hair gray.

I am not a scientist or a doctor, so I really can’t comment here, but I bet my Pharm D.  children, and MD friends, might chime in with their opinion, which is sincerely encouraged and welcome.

Please read on, and share comments.

Study Blames a Chain Reaction That Makes Hair Bleach Itself from the Inside Out

Feb. 25, 2009 — Scientists may have figured out why hair turns gray, and their finding may open the door to new anti-graying strategies.

New research shows that hair turns gray as a result of a chemical chain reaction that causes hair to bleach itself from the inside out.

The process starts when there is a dip in levels of an enzyme called catalase. That catalase shortfall means that the hydrogen peroxide that naturally occurs in hair can’t be broken down. So hydrogen peroxide builds up in the hair, and because other enzymes that would repair hydrogen peroxide’s damage are also in short supply, the hair goes gray.

Putting the brakes on that chemical chain reaction “could have great implications in the hair graying scenario in humans,” write the researchers, who included Karin Schallreuter, a professor clinical and experimental dermatology at England’s University of Bradford.

The study appears online in The FASEB Journal; the FASEB is the Federation of American Societies for Experimental Biology.

    Ive found little grays on the side of my head that keep popping up! At first it didnt bother me but then they started to become noticable! How have you been Suburban? Are you excited for fall and winter? I love the fall colors, but the winter isn’t a friend of mine!

    It must be the wedding worries…..since most people associate graying of their hair with stress. I try to think of gray hair as a sign of wisdom….lol!!!
    I love fall for only a short time, during the color changes of leaves. After that I wish we could skip over winter season and start with spring all over again….wishful thinking!! I love spring!!!!
