As we age, the pigment cells in our hair follicles gradually die. When there are fewer pigment cells in a hair follicle, the strand of hair that grows from that follicle will no longer contain as much melanin and will become a more transparent color — like gray, silver, or white. This is why hair often turns gray as we get older.
