Garnier Olia Dark Brown 4.0 (1183) is a permanent hair color that delivers rich, natural dark brown hues with 100% gray coverage. Powered by a 60% oil blend, including sunflower and camellia seed oils, this ammonia-free formula provides vibrant color while visibly improving hair quality. The non-drip, velvety cream texture ensures an easy application, leaving hair hydrated, silky, and up to 3x shinier than uncolored, unwashed hair.
