I think the title is misleading. From the article: Pain in mice triggered the release of adrenaline and cortisol, making their hearts beat faster and blood pressure rise, affecting the nervous system and causing acute stress. This process then sped up the depletion of stem cells that produced melanin in hair follicles. ... In another experiment, the researchers found they could block the changes by giving the mice an anti-hypertensive, which treats high blood pressure. ------------- So, while stress may cause high blood pressure, it appears high blood pressure causes the white hair per the data in this article. I'm pretty sure things other than stress may also cause high blood pressure. From the article's title, they blame stress. What about all the other things that cause high blood pressure? Then there is discussion on how to stop this from happening by blocking a protein which appears valid, but still a misleading title.
