spartan max2 Posted January 23, 2020 #1 Share Posted January 23, 2020 Quote Lord Byron put it down to sudden fears, which took their toll on men at night. For Wordsworth it was shocks of passion that swiftly turned hair white. But while hair cannot lose its colour in an instant – at least not without help from a bottle of bleach – scientists at Harvard University have shown how stress can, over time, speed up the greying process. Ya-Chieh Hsu, a stem cell biologist, found that stress causes nerves involved in the fight-or-flight response to pump out a hormone which wipes out the stem cells used to make hair pigments. https://www.theguardian.com/science/2020/jan/22/stress-speeds-up-hair-greying-process-science-confirms 2 2 Link to comment Share on other sites More sharing options...
Habitat Posted January 23, 2020 #2 Share Posted January 23, 2020 By that reckoning, stress must increase with age, as most people grey with age. I don't accept that. A lot of people feel greater stress at a young age, than later. 2 Link to comment Share on other sites More sharing options...

The title should be that study confirms stress hormones accelerates the loss of pigments in the hair. So it just speeds it up.

Habitat Posted January 23, 2020 #8 Share Posted January 23, 2020 You would think this could be tested easily enough, by comparing a group of war veterans who experienced a lot of combat, and another group not so exposed. 2 Link to comment Share on other sites More sharing options...
spartan max2 Posted January 23, 2020 Author #9 Share Posted January 23, 2020 Also, poor mice . Quote The Harvard team made their discovery through a series of experiments that measured the effect of stress on the hair colour of mice. The animals were stressed over several days by being restrained for four hours a day, Monday to Friday, or through combinations of damp bedding, rapid changes to lighting and having their cages tilted. 1 Link to comment Share on other sites More sharing options...

I've noticed it on world leaders over the years. Fresh as a daisy taking office, some of them, but grey-headed and kinda haggard after it. 1 Link to comment Share on other sites More sharing options...
Crikey Posted January 23, 2020 #12 Share Posted January 23, 2020 Going a step further to actual baldness, somebody once asked a Star Trek producer/director(?)- "Why haven't they found a cure for Picard's baldness in the 21st century?", and he replied- "Because in the 21st century nobody cares about being bald, it's not an issue".. 1 Link to comment Share on other sites More sharing options...
Habitat Posted January 23, 2020 #13 Share Posted January 23, 2020 I remember a few years ago, a treatment that would restore the original colour was touted, pending safety trials, but no more heard. Link to comment Share on other sites More sharing options...
