Garnier Olia is the first home hair colour powered by oil, not ammonia. A breakthrough in hair colour, the formula has been designed with a high oil content using four natural flower oils, eliminating the strong chemical odour and replacing it with Olias addictive signature floral fragrance. The power of oil ensures a consistent, vibrant colour that leaves hair looking visibly healthier, with perfect grey coverage. Hair is 35% softer and 17% shinier* with the silicone-free Silk and Shine Conditioner, leaving your hair feeling naturally healthy. *instrumental test.
