Could gray hair be reversed?

Scientists may have found a way to turn gray hair back to its original color.

Hair color is determined by two things working together: hair follicle stem cells and color-producing stem cells. If they stop working together, your hair turns gray.

Now, researchers have identified a protein that is the link between the two types of stem cells. And they've figured out how to turn it on to get those cells working together again.

Scientists at New York University have already used the technique to change the hair color on mice.
