Garnier Olia Hair Colouration Dark Brown 3.0 is a deeply rich and intensely pigmented permanent hair color that delivers a strikingly beautiful, pure, and glossy dark brown shade with remarkable depth, strength, and a brilliant mirror-like shine that makes your hair look incredibly healthy, vibrant, and professionally colored from root to tip. If you are looking for a true, deep dark brown that is rich, intense, and full of natural-looking dimension without any unwanted warmth or brassiness, this is the perfect shade for achieving a flawlessly dark and deeply attractive hair color result at home.

What makes Garnier Olia genuinely exceptional and superior to every ordinary permanent hair color is its revolutionary Oil Powered formula, the first permanent hair color activated by a unique blend of 60% natural flower oils with absolutely no ammonia. By replacing harsh ammonia with the natural power of Argan Oil, Sunflower Oil, and Camellia Oil, Garnier Olia opens the hair cuticle gently and naturally to drive rich dark brown pigments deep and evenly into every strand without any of the unpleasant chemical smell, scalp irritation, or long-term hair damage that traditional ammonia-based dyes are notorious for causing. The result is a coloring experience that is significantly more comfortable, pleasant, and respectful of your hair and scalp health from start to finish.

The intensely pigmented formula delivers exceptionally even, consistent, and long-lasting dark brown color with complete and seamless gray coverage and a breathtaking glossy finish that makes every strand look deeply nourished, brilliantly shiny, and beautifully healthy. Suitable for all hair types and dermatologically tested, Garnier Olia Hair Colouration Dark Brown 3.0 is the perfect choice for anyone who wants a pure, intense, and stunningly rich dark brown hair color with a gentle, oil-powered formula that leaves hair feeling noticeably softer, shinier, and in genuinely better condition than before coloring.
