We have nothing against gray hair. If it looks great on you (yes, we're thinking of you, Jamie Lee Curtis), then go for it. But if you can't quite give up your brunette, ginger, or blonde self, you'll be interested in this scientific breakthrough.
An international team of researchers has been mapping out the genes that cause different hair traits, including unibrows, balding, and curly hair. To do this, they looked at 6,000 people in Latin America (because they have so much genetic variation). In the process, the scientists isolated THE gene that causes hair to lose its pigment--or, in other words, turn gray.
Why is this important? Because soon scientists will be able to figure out how the gene interacts with others to cause hair to lose color and then how to turn it off. And that could include products that keep your natural hair color--forever!
Of course, there are other factors besides this gene that cause hair to go gray. In fact, genes play a small role. Aging is the biggest reason, along with climate, pollutants, chemicals, and even some medications.
Still, a future without hair dyes would be SUCH a time saver! We can hardly wait!
