K18 TripleBright Oxidation Defense Purple Shampoo 125ml

K18 TripleBright Oxidation Defense Purple Shampoo is a foaming purple shampoo made for blonde, highlighted, lightened, silver and grey hair. Ordinary purple shampoos only tint over yellow tones. This one targets the cause of brassiness, which is oxidation from metals and minerals picked up from hard water and everyday washing. Its triple-action formula first lifts out those brass-causing deposits. It then neutralises yellow and orange tones with precision violet pigment, without staining or leaving a purple cast. Finally, a protective biopolymer helps defend against brassiness returning. The light foam texture is easy to apply evenly, so you get brighter, cooler, fresher-looking blonde between salon visits. According to K18, a single wash can remove up to three months of hard water brass.

Who is this Purple Shampoo Suitable For

• Natural and bleached blondes who want to keep their tone bright and cool
• Highlighted, balayage and lightened hair that turns brassy over time
• Silver and grey hair that looks dull or yellowed
• Anyone dealing with hard water metal and mineral build-up
• Clients who want to neutralise brass without over-toning or staining
• Hairdressers wanting a corrective step before or after lightening services

How to Use K18 TripleBright Oxidation Defense Purple Shampoo

1. Apply 2–3 pumps of the foam shampoo to wet hair.
2. Spread evenly and lather from roots to ends.
3. Leave on for 1–3 minutes only, then rinse thoroughly.
