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.

Only product I have ever tried that immediately got rid of brassiness!! I am 70 and have never colored my hair, however my ends turn orange and blue products turn my hair purple; hurry and buy some, you won’t be disappointed.

Hands down the absolute best toning shampoo that I have ever used. Comes out as a foam and a little bit goes a long way! I bought mine back in May and still have half of a bottle left.
