Experience the revolutionary approach to permanent hair colouring with this premium ammonia-free collection designed to deliver exceptional results with superior comfort and care. The INOA Fundamental Series features a comprehensive range of classic shades from the deepest Black (1) to the lightest Lightest Blonde (10), with specialised options including Deep Cover shades for enhanced grey coverage and Fundamental Golden variants for sophisticated warm dimension. This innovative collection represents the pinnacle of L'Oreal's colour technology with its patented Oil Delivery System that utilises 60% oil to propel colour pigments deep into the hair fibre without ammonia, creating results with up to 48% more shine whilst ensuring optimal scalp comfort during application. The vegan-friendly formulation combines professional-grade colour performance with gentle processing, eliminating the harsh chemical smell typically associated with permanent colouring whilst still delivering up to 100% white hair coverage. For those seeking the perfect natural foundation shade, the Clear option provides maximum versatility for customisation or subtle enhancement without dramatic colour change.
The Fundamental Series delivers exceptional colour results through its unique oil-powered technology that transforms the colouring experience. This comprehensive collection offers the perfect shade for every need, from the richness of Dark Brown (3) to the luminosity of Very Light Blonde (9), with carefully calibrated formulations that deliver consistent, predictable results. The Deep Cover variants (4.0, 5.0, 6.0, 7.0, 8.0, 9.0) provide enhanced coverage for even the most resistant grey hair, whilst the Fundamental Golden options (5.3, 6.3, 7.3, 8.3, 9.3) add sophisticated warm dimension with natural-looking results. Each 60ml tube contains concentrated colour cream that mixes effortlessly with the dedicated INOA oxidants to create a fluid formula that's easy to apply, with perfect consistency for both virgin applications and regrowth touch-ups. Unlike conventional permanent colours, this ammonia-free formulation works at a moderate pH that minimises damage whilst still delivering professional-grade results with exceptional longevity and fade resistance.
What distinguishes INOA's revolutionary technology from standard permanent colours is its exceptional balance between performance and hair care benefits. The oil-based delivery system creates a protective barrier around the scalp during processing, dramatically reducing irritation and discomfort whilst simultaneously nourishing the hair fibre for healthier-looking results. This innovative approach ensures maximum molecule penetration for superior colour intensity and coverage, without the harshness and chemical smell typically associated with ammonia-based formulas. The fluid texture applies smoothly with perfect saturation, distributing consistently even on resistant areas for uniform results from root to tip. With development requiring just 35 minutes, this efficient system delivers salon-quality results in less time than many conventional permanent colours. Each shade has been meticulously calibrated to deliver predictable, natural-looking results with exceptional clarity, whether providing sophisticated neutrality with the standard Fundamental shades or enhanced warmth with the Golden variants. Combining professional-grade colour performance with superior comfort and care, this premium permanent system offers the perfect balance of natural-looking coverage, enhanced shine and exceptional hair protection for truly transformative yet gentle colouring results.
