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.

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.

This has made the single biggest difference in my hair since moving to a state with incredibly hard water. My hair gets sooo brassy and even the toner fades after just one wash but this stuff keeps me looking ashy. I wish it were a conditioner rather than a shampoo but it’s the closest in pigment to the OG mask from pravana (bring back the old formula! Or challenge to K28–make a mask!!! Shampoo is soooo drying. But the dye in the purple is perfect. Just make a conditioning mask instead!! Perfect purple

- Yolanda R.Verified BuyerRated 4 out of 5 stars1 week agoSo far so good.
The first time I used it I probably didn't put enough or left it on the right amount of time. The second time I do see a difference. My hair doesn't look as brassy. Wish the bottle was a little bigger for the price but oh well.
