Hair-Coloring Stem Cells in the Hair Germ Compartment Trigger Pigmentation

Some stem cells have a special capacity to mobilize among growth compartments in hair follicles; however, they get stuck with age in people. Hence, they lose their capacity to mature and retain hair color, as per new research.
