Violet toning shampoo that cancels brassy yellow in blonde, silver and bleached hair Cool Silver Shampoo from REF is a sulphate-free violet shampoo built around CI 60730 (Ext. Violet 2). The pigment deposits a thin violet veil on the cuticle during the wash; on the colour wheel violet sits opposite yellow, so the warm tones that build up in lightened, grey and sun-faded hair read visually neutral. Gentle coco- and amino-acid based surfactants clean without the harsh detergent feel of SLS, and the formula is vegan. Why Choose It? Neutralises yellow and brassy tones in blonde, silver, grey and bleached hair via CI 60730 violet pigment Sulphate-free wash base — Coco-Glucoside, Cocamidopropyl Betaine and Sodium Lauroyl Sarcosinate clean gently and respect colour Polyquaternium-10 and Polyquaternium-7 condition the cuticle so pigment lays down evenly and the strand rinses smooth Dimethiconol finishes the surface for a cool, reflective shine instead of a dull matte cast Vegan formula, free of parabens and SLS/SLES sulphates Best For Blonde, silver, grey, bleached and highlighted hair that pulls warm or yellow between salon visits.
