Scientists have found the gene responsible for grey hair and a cure will be possible in the future.

Scientists say that they have found the first gene linked with gray hair. They did so after a genetic analysis of more than 6,000 people who live in Latin America, but are of mixed ancestry. They found that genes do play a role in the graying of hair.

"We already know several genes involved in balding and hair color, but this is the first time a gene for graying has been identified in humans, as well as other genes influencing hair shape and density," said study author Kaustubh Adhikari, from University College London, in England.

"It was only possible because we analyzed a diverse melting pot of people, which hasn't been done before on this scale. These findings have potential forensic and cosmetic applications as we increase our knowledge on how genes influence the way we look," he said in a college news release.

The gene that is linked to gray hair is called IRF4, a gene that we knew played a role in hair color, but hadn't been able to connect it to the loss of color in hair.

Now that we have the gene, we might be able to find a way to delay the gradual shift of color, and it could also help us understand why and when we age. The researchers also found that another gene called PRSS53 seems to influence hair curliness.

"It has long been speculated that hair features could have been influenced by some form of selection, such as natural or sexual selection, and we found statistical evidence in the genome supporting that view," Adhikari said.

"The genes we have identified are unlikely to work in isolation to cause graying or straight hair, or thick eyebrows, but have a role to play along with many other factors yet to be identified," he said.
