LONDON -- Do you remember the feeling after finding your first gray hair? Yeah, me too! Scientists now know what makes us go gray and -- it's in our genes.
The study published in Nature Communications also says grays could be associated with your ethnic background.
The gray gene was discovered by studying the scalp and facial hair of more than six thousand people who had a mix of European, Native American and African ancestry.
They found that gray hair is more common in people of European origins with lighter hair color while people of Asian and African ancestry gradually go gray.
But hey, maybe going gray isn't so bad. Twenty-somethings have been embracing the granny hair trend for some time now.
So don't stress over a little gray, after all, silver is sexy!
