Secrets of gray hair revealed: Scientists may have figured out why our hair does this

A study published in the journal Nature reveals that a certain type of stem cell gets "stuck" in our hair follicles — potentially causing gray hair and leading to a loss of hair color.
He was the leader of the research team. The melanocyte stem cells in our hair follicles are a specific stem cell that produce and maintain the pigment in our hair. The melanocyte skin cells that were not "stuck" but still could travel in the hair follicle kept their ability to produce pigment.
"These findings suggest that melanocyte stem cell motility and reversible differentiation are key to keeping hair healthy and colored," he also said.
