Daily Mail -- For any woman who has sighed with exasperation over her grey hairs, it is a thought that really makes the mind boggle. What if you could ditch the dye and regain the hair color that you grew up with? Surely, you might think, this is the stuff of science fiction. But according to the experts at Centre Charles Zviak, L’Oreal’s research and development HQ, it is science, but by no means fiction. If the company’s plans come good, going grey will one day be a thing of the past.
