For the vast majority of people, graying hair is not down to something you have done, but to genetic factors beyond your control, Nina Goad of the British Association of Dermatologists told the BBC.
Several studies in rodents have suggested a link between stress and the appearance of grey hairs. One study in 2011 even suggested that long-term exposure to stress, which has been shown to affect our DNA, could tweak the genes that give our hair its hue.
And a 2009 study suggested that the reason hair loses its colour is because as we get older, we produce less and less of a special protective protein that buffers the hair against a natural process of bleaching from within.Luckily, mice aren’t people (and most of them are grey already anyway).There’s little research to support the idea that the findings from those studies happen in humans.
