New Stem Cell Discovery Offers Hope for Gray Hair Reversal

Scientists have discovered that stem cells may get stuck as hair ages, resulting in greying hair. The study focused on melanocyte stem cells in mice and found that as hair ages, increasing numbers of these cells get stuck in the stem cell compartment of the hair follicle bulge, where they remain. The researchers suggest that if their findings hold true for humans, it could open up a potential way to reverse or prevent grey hair by helping jammed cells to move again between developing hair follicle compartments.
