What happens when hair turns gray? Hair follicles have pigment cells known as melanin. These cells give your hair its color. But over time, hair follicles can lose pigment, resulting in white hair. What causes gray hair? Aging, genetics, stress, and hormones. But mostly aging. Some people try to cover up those grays but we think you should flaunt it! Got to love those snowy locks. Youre stunning, you silver fox! #scienceofhair #scienceofbeauty #beautytok #skintok #hairtok #scienceofaging
