How is TripleBright different from traditional purple shampoos?
TripleBright is not a color-depositing purple shampoo. Traditional purple shampoos temporarily tone hair with basic color correction that can turn hair purple, but don’t target the underlying cause of brassiness: oxidation, such as metals + minerals in hard water.
TripleBright is a breakthrough triple-action formula that not only neutralizes existing brassiness without turning hair purple, but 1 wash removes up to 3 months of brass from hard water*, while also defending against future brass. The non-staining, easy-to-apply foam rinses with water and allows for targeted application.

Really like the Triple Bright. Does not dry my hair, removes the "yellow" or blonde that my grey hair gets. For me this works the best of any "purple" shampoo I have tried.

Just had my hair bleached a little for the very first time as I’m grey blending . My hairdresser recommended that I use K18 especially as I swim 2/3 times a week and chlorine ruins the hair . I of course took his advice and my hair has refrained from the yellowing . Just purchased my second bottle . Hooked .
