I don't think I've ever had a product that did that but I do spend time in sun, wind, and smokey bars and those things do make my hair dull and yellow. I do vinegar rinses to remove anything clinging to my hair and use my red/gold corrector once a week or so. My hair isn't as sparkly and shiny as some gray/white hair I see, but it wasn't ever very shiny before it was gray either so I wasn't really expecting much. I still love my gray hair. I get more compliments than I ever did as a brunette.
