K18 TripleBright oxidation defense purple shampoo

K18 TripleBright oxidation defense purple shampoo

A new standard in blonde maintenance—targeting the cause of brassiness, not just the symptom.

This next-generation purple shampoo from K18 Hair goes beyond traditional toning. Powered by triple-action technology, it works to remove mineral and metal buildup from hard water, neutralize existing brassiness, and help prevent future oxidation. The result is brighter, more even blonde tones that last longer—without staining, over-toning, or compromising the hair.

Recommended for:

• Blonde, highlighted, or lightened hair
• Hair exposed to hard water or mineral buildup
• Clients experiencing brassiness, dullness, or uneven tone
• All hair types and textures

Benefits:

• Removes buildup from metals and minerals that contribute to brassiness
• Neutralizes yellow and orange tones without over-toning or purple staining
• Helps prevent future oxidation during washing
• Supports a more even, refreshed blonde tone
• Lightweight foam texture allows for precise, even application

How to use:

• Apply 2–3 pumps to wet hair
• Distribute evenly from roots to ends and lather
• Leave on for 1–3 minutes
• Rinse thoroughly
• Use as needed based on tone and buildup

Loshen & Crem’s recommendation:

This is not a traditional purple shampoo—and that’s exactly why we love it. Instead of layering pigment over the hair, it addresses what’s actually causing brassiness. Ideal for clients dealing with hard water or dull blonde that doesn’t respond to classic toning shampoos. Use it as a corrective step, then maintain with a nourishing routine to support the integrity of lightened hair.

Ingredients:

• Ionic detox: helps remove brass-causing metals and minerals
• Precision violet technology: neutralizes tone without staining
• Biopolymer shield: helps prevent reattachment of minerals during washing
