K18 TripleBright Anti-Oxidation Silver Shampoo is a purple shampoo for blonde and highlighted hair. It neutralises existing warm tones, and the brand states that it removes metals and minerals. It goes on wet hair, lathers from roots to ends and stays on for 1-3 minutes before the rinse.

What the ingredient list shows

Water opens the list, with Cocamidopropyl Hydroxysultaine, Sodium Cocoyl Alaninate and Sodium Methyl Cocoyl Taurate behind it. Further down sit three chelating agents: Trisodium Dicarboxymethyl Alaninate, Sodium Phytate and Tetrasodium Glutamate Diacetate. The brand's line on metals and minerals rests on them. Acid Violet 43 (CI 60730) is the violet colourant, and after Fragrance (Parfum) come eight named fragrance allergens.

• Sodium Cocoyl Alaninate: entry 3
• Trisodium Dicarboxymethyl Alaninate: entry 8

What to expect

A wash like any other shampoo, with one difference: the wait. The lever is coverage and time, so spread the lather evenly through all the hair and let it sit for the full time before rinsing. The directions give a range rather than one figure; the exact time is the colourist's call.

Who it is for

• Colourists sending blonde and highlighted clients home with a shampoo for warm tones between appointments.
• Blonde or highlighted hair showing warm tones: the brand describes the shampoo as one that neutralises them.
• Salons that want a lathering violet shampoo with a short leave-on time.

Who it is not for

• Anyone sensitive to the fragrance allergens on the list: Hexyl Cinnamal, Hydroxycitronellal, Citrus Limon (Lemon) Peel Oil, Tetramethyl Acetyloctahydronaphthalenes, Limonene, Benzyl Salicylate, Citrus Aurantium Peel Oil and Citrus Aurantium Flower Oil.
• Hair that is neither blonde nor highlighted: the brand writes this shampoo for those two.
