A study by researchers from the NYU Grossman School of Medicine finds that some stem cells can transition between growth areas in hair follicles but get stuck as people get older and lose their ability to mature and sustain hair color, according to a release from NYU Langone Health.The team’s study, published in the scientific journal Nature on Wednesday, centered on cells found in the skin of mice and humans called melanocyte stem cells or McSCs. Hair color, the researchers explain, is controlled based on nonfunctional but continually growing pools of McSCs in hair follicles to become mature cells that make protein pigments responsible for hair color.The study notes McSCs are plastic, which means during hair growth, the cells move back and forth as they transition between parts of the developing hair follicle.
