There could finally be a way of stopping hair from going grey. Thanks to researchers in the US, stem cells that have the unique ability to move between growth compartments in hair follicles were discovered.
As humans grow older, the melanocyte cells in our hair follicles die. This causes a depletion in the pigment resulting in grey hair over time.
To stop this, the team found that as our hair ages, sheds and repeatedly grows back, more of these stem cells become stuck in a compartment called the hair follicle bulge.
