George Clooney never to have gray hair again?

 Would you want to change his look?  Does George Clooney need to get rid of the gray hair? Gray hair could be cured once and for all. Science has just broke the secret code to stop hair from going gray.

Gray hair is, along with premature balding, one of the greatest fears of image-conscious men and women everywhere, but it may soon be a thing of the past. Scientists at the Ito Lab at New York University's Langone Medical Center have identified the proteins that cause gray hair, which could lead to an eventual cure.
Scientists have known for years that hair color is determined by the stem cells that guide the development of hair follicles working together with color-producing stem cells called melanocytes. Today, NYU researchers announced they had isolated the wnt protein, which serves to coordinate pigmentation between the two types of stem cells.
Already, scientists have managed to start with black mice and once they inhibited the Wnt pathway in their melanocyte stem cells, they eventually turned gray.

"Mouse and the human hairs are very similar in the way that they are structured and the way they contain melanocyte stem cells. We found that the wnt signaling pathway is activated the same way," said Piul Rabbani, a grad student in NYU's Langone Medical Center who led the study, told ABC News.
This breakthrough means that one day the wnt protein could be added to hair grooming products or supplements and help turn back the clock.
"Our hair follicles and the pigmentation from the melanocyte stem cells work in a very similar fashion, so it definitely can be applied at some point in the future," Rabbani told ABC News.
