Scientists have released research that shows that stress can cause hair to turn white
The team from Harvard have published their data
Scientists believe they have uncovered "new evidence" that shows how acute stress can cause hair to turn white prematurely.
Mice experiments have revealed that extreme levels of stress causes the sympathetic nervous system, which is responsible for the body's rapid involuntary response to dangerous or stressful situations, to become hyperactive.
This, in turn, drives the rapid depletion of stem cells responsible for hair colour, leading to pigment loss and development of white hair.
The team says their findings, published in the journal Nature, contradicts previous theories that stress-related grey hair is a result of immune attacks or stress hormones such as cortisol.Published: by Radio NewsHub
