TripleBright oxidation defense purple shampoo
Breakthrough triple-action protection for brighter, longer-lasting blonde
The first triple-action purple shampoo to remove metals + minerals, neutralize existing brass, and defend against future brassiness for blonde like new, hair like new*.
Get started here.
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.

- Hazzel J.Verified BuyerRated 5 out of 5 stars1 hour agoThe best purple shampoo I've tried!!!
This is honestly the best purple shampoo I’ve tried so far! After getting a balayage, I noticed that my bangs still looked a little too yellow and brassy in person, even though my hair had already been toned. The color just wasn’t complementing my skin tone the way I wanted it to. After using the K18 purple shampoo, the difference was amazing! It toned down the yellow and brassiness beautifully, and the color came out soooo perfect. 😍 I’m genuinely impressed with how much of a difference it made. I love K18 products so much...they have definitely become my go-to for my bleached hair!
