Scientists may have discovered why hair turns grey

Scientists believe they have discovered the mechanism
for hair turning grey, which could help develop treatment to alter cells in order to reverse or halt
the process. A new study suggests stem cells may get stuck
as hair ages and lose their ability to mature
and maintain hair colour. Certain stem
cells – which are able to develop into many different cell types – have a unique ability to transition between growth compartments
in follicles
. These cells lose the ability to move with age, resulting in greyness.
