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.

Does TripleBright work on all hair types?

Yes, TripleBright works on all hair types and textures. It brightens all highlighted and lifted tones by defending against oxidative stress and reducing brass—delivering brighter, longer-lasting blonde for everyone.

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.

How much TripleBright should I apply?

We recommend using 2-3 pumps of TripleBright purple shampoo per application. Apply to wet hair, distributing evenly and lathering from roots to ends.

Reviews Summary

Customers say this purple shampoo foam brightens blonde hair and effectively reduces brassiness without leaving a purple tint. The foam texture distributes easily through hair with just 1-2 pumps, making application simple and lightweight. Users appreciate that their hair feels soft and smooth after use, rather than dry or stripped like with traditional purple shampoos. Many note visible results after just one use, with hair looking brighter and more salon-fresh. The product maintains cool tones between salon visits and helps remove buildup. Some customers mention needing extra conditioning after use, and a few find the foam consistency takes getting used to.

Holy grail of purple shampoo
I absolutely love this stuff. I have tried literally every purple shampoo on the market, including some blue shampoos as well as black. This stuff transformed my yellow hair and is making my grey grow grow so much more tolerable. I'm so glad that the purple shampoo search is finally over.
