You can pluck it. You can dye it. But you can’t beat it. Gray hair is genetic. That’s the word from an international group of researchers, who have identified the first gene linked with gray hair, called IRF4. A team at University College London conducted a genetic analysis of more than 6,000 Latin Americans of mixed ancestry to prove that genes determine if your hair will turn gray or not. This particular group was chosen because of its extreme diversity. The study said, “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.” ***So if you’re going gray, and you’re upset about it, yell at your mother.
