(Newser) – Scientists may have discovered the key to keeping your locks colorful. Gray hair results from a missing "signaling" protein, called Wnt, in the melanocyte stem cells that help create one's hair color, a new study suggests. Genetically manipulating Wnt may prevent the graying process—and researchers have already restored coloration in mice, the Telegraph reports. “We have known for decades that hair follicle stem cells and pigment-producing melanocyte cells collaborate to produce colored hair, but the underlying reasons were unknown,” says a scientist.

“We discovered Wnt signaling is essential for coordinated actions of these two stem cell lineages and critical for hair pigmentation.” The results could also help fight melanocyte-related diseases like melanoma.

That will never be released to the public. The hair dye industry won't allow it.

Obama aint the best president ever... but I love him for one thing: He's really good at pissing off the little minded conservatives.
