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.

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.
