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.

*k18hair.com/disclaimers
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.
No. When used as directed, TripleBright purple shampoo’s precision violet technology expertly neutralizes brassiness without overtoning or staining.
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.
We recommend using 2-3 pumps of TripleBright purple shampoo per application. Apply to wet hair, distributing evenly and lathering from roots to ends.

    No Brass

    complimentary from k18biomimetichairscience: I love how this shampoo removes the brassy look from my hair. I like to keep the platinum blonde color and this helps. It also leaves my hair brighter. I don’t leave on very long to prevent a purple hue.

    Great for highlights!

    This purple shampoo has been really fun to use because of its foaming techniques. It doesn’t stain my nail beds as bad as typical purple shampoo. My hair took the violet tones very nicely, and I didn’t have any purple patches. This product also smells really good and I love that it has metal removal technology. complimentary from k18biomimetichairscience

    Brightening Effect Subtle

    This product was gifted by K18 Biomimetic Hairscience. I have color treated blonde hair and typically use a purple shampoo weekly as my hair pulls more brassy after coloring. The foamy texture of the product was interesting but I did find it a bit hard to get into my hair as it kept sliding off my hand and I would lose bits of it before I could get it applied. Once in my hair it did take quite a bit to cover the area needed. I do think I prefer a more thick shampoo texture as that feels like it coats my hair better. The experience while my hair was wet and lathered up was ok but once I washed it out it did feel like my hair was very tangly compared to how it typically feels. Post shower it was quite difficult to comb through even after conditioning. After my hair was dried it appears to have toned down the brassiness slightly but not as much as I'm used to seeing. My hair feels dry on the ends compared to how it usually does so overall I don't think this product is right for my hair type but it could work for others.

    Thank you so much for taking the time to try the TripleBright oxidation defense purple shampoo and share such detailed and honest feedback, Lindsey! We really appreciate you giving it a thorough try and sharing both the positives and areas where it didn't quite meet your expectations.

    We're glad to hear that you noticed some toning of the brassiness, which is what TripleBright is designed to deliver. At the same time, we completely understand your concerns about the foamy texture being harder to apply, the tangly feeling during washing, and the dryness you experienced on your ends. We know that texture preferences can vary greatly from person to person, and it sounds like you have a good understanding of what typically works best for your hair.

    We want you to have the best possible experience with K18 and I would love to troubleshoot with you on application techniques that might help with coverage and minimize any dryness, if you would like please send us an email at hello@k18hair.com.

    Great product and really easy to use!

    gifted by k18biomimetichairscience. Loved this purple shampoo!! It was sooo easy to use! I left it on for about 5 minutes and it really helped with my brazziness, it didn’t make my hair any dryer and frizzy, and it really applied pigment. Loved it!
