Genes to blame for gray hairs?

December 1, 2009 2:56:02 PM PST
Many people like to blame their jobs or their children or even their spouses for their gray hair. But a stressful lifestyle may actually have little to do with your locks turning silver. A study in the journal PLoS ONE finds that, especially in women, genetics play a key role in controlling when and how much your hair turns grey.

Scientists studied more then 200 identical twins and found very little difference in natural hair color. But when they looked at non-identical twins, whose genes differ, the amount of gray was varied.

So you can blame your parents for the cost and hassle of coloring over that grey.
