Scientists discover ‘why stress turns hair white’

Scientists say they may have discovered why stress makes hair turn white, and a potential way of stopping it happening without reaching for the dye.

In experiments on mice, stem cells that control skin and hair colour became damaged after intense stress.

In a chance finding, dark-furred mice turned completely white within weeks.

The US and Brazilian researchers said this avenue was worth exploring further to develop a drug that prevents hair colour loss from ageing.

Men and women can go grey any time from their mid-30s, with the timing of parental hair colour change giving most of the clues on when.

After that, additional de-stressing benefits continue to add up but at a slower rate. The image is in the public domain.
