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.

will TripleBright turn my hair purple?
No. When used as directed, TripleBright purple shampoo’s precision violet technology expertly neutralizes brassiness without overtoning or staining.
Will TripleBright stain my hands or clothes?
No, TripleBright will not stain your hands or clothes. When used as directed, the non-staining and easy-to-apply foam format rinses with water.

- Patricia S.Verified BuyerRated 5 out of 5 stars1 week agoRemoved all brassiness!
I've only used it once so far and it removed that yellow, brassiness my silver tends to get. All gone!
I plan on continuing use as it was also very gentle on my hair.

- Debbie H.Verified BuyerRated 5 out of 5 stars1 week agoLovely shiny colour + softness
Gives lovely shiny colour plus adds softness — I use it with K18 modular leave-in conditioner while growing out bleach. Great for me with inherited white roots. Really helped my curls and reduced breakage. My hair feels much softer and looks so shiny. Amazing product.
