Researchers find possible cure for gray hair

LOS ANGELES

Researchers at New York University turned hair on mice from gray back to its natural sheen without hair coloring.

They discovered a protein that re-activates the color producing stem cells in hair follicles.

Researchers said the structure of human hair is similar to mice, so they have high hopes for the future.

Americans spent more than $2 billion in 2010 on home coloring products.
