This isn't a lifting developer; it's the one that opens the hair enough for colour molecules to settle without frying the lot. The 1000ml bottle is built for mixing, not guesswork.\u003c\/p\u003e\u003cp\u003eUse a 1:2 ratio with Wella colour or a compatible permanent dye. Twenty volume holds steady through processing — you're not fighting oxidation fade mid-application. Keep the bottle sealed between uses; once opened, it starts losing potency within weeks.\u003c\/p\u003e","brand":"Wella","offers":[{"title":"Default Title","offer_id":57392123281785,"sku":"X707444","price":25.99,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/www.checkoutbeauty.com\/products\/wella-professionals-wella-welloxon-perfect-6-20vol-developer-1000ml","provider":"Checkout Beauty","version":"1.0","type":"link"}
