what specific type of product do you mean? there aren't any that are specifically for gray hair. i just found that the cccc gives my hair extra shine and that gray hair looks great when it shines.
i do add ardell red/gold corrector the to the cj argan & olive oil conditioner to brighten up the white from time to time, but that is a product i add to a regular conditioner.
i am a curl junkie junkie and use most of her products. some on a daily basis, others from time to time.

i just meant any products anyone has found that gives their gray hair lots of shine, inadvertently. like oh, look how this styler, whatever... makes me hair shiny! :-)
