What Causes White Hair to Yellow?
As you age, the pigment in your hair fades and the hair loses its original color, becoming white or gray. If the pigment fades in blended sections, creating a salt-and-pepper look, many people choose to color the white hair to match their original hair color or to let the salt-and-pepper look progress naturally. However, when all of your hair has turned white, the tresses may turn yellow and dull over time.
