Scientists from New York University’s Langone Medical Center have found the proteins (wnt) that cause gray hair. This wnt protein coordinates pigment between stem cells that guide development of hair follicles and melanocytes which are color producing stem cells. Scientists were able to inhibit the wnt protein in the melanocyte stem cells and turn a mouse’s hair gray. This wnt protein may be added to hair products or supplements in the future to cure gray hair.
