Violet pigment duo that cancels brassy yellow on blonde, silver and bleached hair
Cool Silver Duo pairs the full 600 ml sizes of REF Cool Silver Shampoo and Conditioner — a two-step toning routine for blonde, silver, grey and bleached hair that tends to pull warm. The shampoo cleanses on a sulphate-free wash base and lays down CI 60730 (Ext. Violet 2), a cosmetic violet dye that sits opposite yellow on the colour wheel and visually cancels the brassy cast. The matching conditioner follows up with conditioning agents and a second pass of violet pigment so tone and feel are addressed in one wash. REF Stockholm formulates the whole brand 100% vegan.
Why Choose It?
- Two-step toning routine — shampoo cleans and deposits CI 60730 violet pigment, conditioner extends contact time on porous mid-lengths and ends
- Sulphate-free wash base — Coco-Glucoside, Cocamidopropyl Betaine and Sodium Lauroyl Sarcosinate clean gently and respect lightened colour
- Polyquaternium-10 and Polyquaternium-7 film-form on the cuticle so pigment distributes evenly and the strand rinses smooth
- Dimethiconol finishes the surface for a cool, reflective shine instead of a dull cast on toned blonde or silver
- Generous 2x600 ml format — full salon-size pair, ready to gift as a duo set
- 100% vegan per REF Stockholm brand standard
Best For
Blonde, silver, grey, bleached and highlighted hair that pulls warm or yellow between salon visits. Suitable for level 8 and lighter, and for sun-faded mid-tones that need a cool reset. The 2x600 ml duo format also makes a complete gift set for a colour-treated friend.
Use 1-3 times a week in place of your regular wash routine, depending on how warm the hair pulls. On very porous or freshly bleached hair start with shorter pigment leave-on times to gauge deposit.
- Wet hair thoroughly with lukewarm water
- Work a coin-sized amount of Cool Silver Shampoo through scalp and lengths until a soft violet lather forms
- Leave the shampoo on for 3-5 minutes so the pigment can adhere to the cuticle, then rinse
- Apply Cool Silver Conditioner to mid-lengths and ends, avoiding the roots on fine hair
- Leave for 2-3 minutes for a deeper tone and feel, then rinse thoroughly with cool water to seal the cuticle
Tips
- If hair runs very brassy, alternate Cool Silver with your regular shampoo rather than using it daily
- Wear gloves if you tone often — violet pigment can stain fingertips and porous surfaces
- Once or twice a week swap the conditioner step for a deeper repair masque for bleached hair to rebuild moisture in porous lengths.
