Garnier Olia 2.0 Black Diamond Hair Dye: Honest Review

For a Great Finds pick rooted in real bathroom routines, Garnier Olia No Ammonia Permanent Hair Dye 2.0 Black Diamond earns its place. The colourant cream and developer mix into a smooth, glossy texture that feels manageable rather than runny, with no sharp ammonia hit. It suits naturally very dark hair or obvious root regrowth before a weekend plan in the UK, though the deep black finish is less forgiving if a softer brown is usually preferred. The included conditioner helps the final rinse feel less stark.
