Why does hair turn white? New discovery explains the science behind gray hair
A study from New York University found that hair color loss with age is partly due to a malfunction in the movement of pigment stem cells within hair follicles. This disrupts their ability to migrate between follicle regions to produce pigment, leading to the appearance of white hair. However, there are currently no proven treatments to restore white hair to its original color, but understanding this mechanism could, in the future, open possibilities for preventing or reversing graying.
