The shampoo cleanses while it tones, brightening highlights and enhancing silver tones. The conditioner pairs calibrated purple pigments with ceramides; Matrix says it neutralizes yellow in one wash and gives 2x more moisture, with shinier, stronger-feeling hair.\u003c\/p\u003e\n\u003cp\u003eFor the strongest toning, use both. For a subtler result, use the conditioner after a regular shampoo. Matrix lists So Silver as suitable for colour-treated and natural hair, from grey to white shades.\u003c\/p\u003e\n\u003cp\u003eThe gift box suits anyone keeping a cool blonde or bright silver between colour appointments.\u003c\/p\u003e","brand":"Matrix","offers":[{"title":"Default Title","offer_id":51280900325623,"sku":"CAN-040902","price":37.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/5682\/5764\/files\/matrix-so-silver-holiday-duo-2026-src_d102691d-de9e-4fc0-9b3b-e7c7ed6d52c4.jpg?v=1791417655","url":"https:\/\/smoothandcharming.com\/products\/matrix-so-silver-holiday-duo","provider":"Smooth\u0026Charming","version":"1.0","type":"link"}
