K18 TripleBright Oxidation Defense Purple Shampoo - Non-Staining Blonde Shampoo Removes + Helps Prevent Brass for Brighter, Longer-Lasting Blonde - For All Highlighted + Lifted Hair Tones (4.2 Fl oz)

Specifications:

K18 Triple-Action Technology: The first triple-action purple shampoo for blonde hair with a breakthrough oxidation defense system designed to remove metals + minerals, neutralize existing brassiness, and defend against future brassiness for all highlighted + lifted tones.
Remove Brass: Unlike traditional blonde toners or shampoos, TripleBright uses ionic detox to target the cause of brass: oxidation from metals + minerals. 1 wash removes up to 3 months of brass from hard water*.
Neutralize Tone: TripleBright won't stain or overtone like a color depositing shampoo. Precision violet technology expertly neutralizes yellow and orange tones, so ideal hair tone is restored and evened* for all highlighted and lifted tones.
Brighter, Longer-Lasting Blonde: TripleBright goes beyond a toning shampoo to defend against future brass. A biopolymer helps prevent the reattachment of metals + minerals during washing for lasting brightness.
Easy-To-Apply Foam Formula: Apply foam shampoo to wet hair, distributing evenly, lathering from roots to ends. Let sit for 1-3 minutes then rinse.
