Description
Achieve a deep, sophisticated dark brown at home – without ammonia – using Garnier Olia 4.0 Dark Brown. Olia is Garnier's ammonia-free permanent colour, driven by a blend of 60% flower oils that carry pigment deep into each strand for intense, radiant colour and none of the sharp ammonia smell traditional dyes are known for. Shade 4.0 is a rich, deep brunette that adds depth and definition, making it a flattering choice for those who want darker, glossier hair or a refined base colour. Darker shades tend to reveal dryness and dullness quickly, which is where Olia stands apart: the oil-powered formula leaves hair visibly shinier and feeling conditioned rather than rough and depleted after colouring. It delivers up to 100% grey coverage, evenly blending white and resistant strands into a uniform dark brown so first greys and full coverage are both handled with ease. The creamy, non-drip texture applies comfortably and spreads smoothly root to tip for consistent, salon-style results. Everything needed for one complete application is included in the kit, a gentle-feeling and cost-effective alternative to the salon. Perfect for anyone seeking a deep brunette with high shine, a more comfortable colouring experience, or a dependable way to cover greys at home. Always follow the enclosed instructions and complete the recommended allergy alert test before each use.
