There is a scientific reason if you have gray hair in your thirties.
At least scientists have discovered a path.
In an experiment with mice, researchers from the United States and Brazil discovered that stem cells that control skin and hair color were damaged by stress, the BBC reports.
The dark fur of small rodents became completely white after a few weeks.
This experience will help find a drug to prevent the change in hair color related to aging.
Even if hair discoloration is often due to aging and genes, we can now say that stress plays a role.
It is not known, however, how stress affects the hair.
Ya-Cieh Hsu, one of the researchers at Harvard University, also says that the damage from stress is permanent.
“I anticipated that stress was bad for the body, but the impact of stress that we discovered was beyond what I had imagined,” he said. After only a few days, the cells that regenerate the pigments were lost. Once lost, you can no longer regenerate pigment. The damage is permanent. ”
