{"product_id":"ref-hair-colouring-system","title":"REF Hair Colouring System","description":"\u003cp\u003e\u003cstrong\u003eREF Hair Colouring System\u003c\/strong\u003e is REF Stockholm's permanent, oxidative cream hair colour for professional use, sold across REF's full shade range (Naturals, Ashes, Coppers, Reds, High Lifts and more, ~76 shades) with up to 100% grey coverage, in 100ml tubes. Like all permanent colour, it is mixed with a REF Peroxide Developer immediately before application: the alkalising system (REF uses a low-ammonia formula, under 2% average ammonia content) opens the hair cuticle so the small, colourless dye precursors can penetrate the cortex, where they react with the developer's hydrogen peroxide to form the final, wash-fast colour molecules.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThis is a hazardous professional chemical product\u003c\/strong\u003e, not an everyday cosmetic, and REF markets it strictly for use by trained colourists. Depending on shade, the formula contains oxidative dye intermediates such as p-phenylenediamine (PPD), toluene-2,5-diamine sulfate and\/or resorcinol, together with ammonia — ingredients that deliver permanent colour change but are also well-documented skin sensitisers, and PPD in particular can occasionally trigger severe allergic reactions. A preliminary sensitivity (patch) test at least 48 hours before every application is strongly recommended, gloves should be worn throughout mixing and application, and the product must never be used on broken, irritated or sunburnt skin\/scalp, or allowed near the eyes. Anyone with a known allergy to hair dye or PPD should not use this product. Sold as professional stock; must be mixed with a REF Peroxide Developer before use, and is not intended for eyebrow or eyelash tinting.\u003c\/p\u003e","brand":"REF Stockholm","offers":[{"title":"10.0
