White hair results from a complete loss of melanin, the pigment that gives hair its color. Grey hair is a mix of colored and white hairs, typically due to a gradual reduction in melanin production. The shift to gray usually starts as reduced melanin in certain hair strands, leading to a salt-and-pepper appearance before potentially transitioning to white.
