Expert Answer:

The hair follicles contain pigment cells called melanocytes, which produce melanin. Gray hair is caused by the gradual reduction of melanin production over time within the hair follicle. The melanocytes in the hair follicles produce less and less melanin, and the result is a loss of hair fiber color strength.
