Garnier Olia Permanent Ammonia-Free Hair Color – Intense Black

Garnier Olia Permanent Hair Color, Ammonia-Free — Deep Black (1.0)

Garnier “Olia” permanent hair dye is an oil-based formula, containing approximately 60% natural oils, ammonia-free, covering gray hair by nearly 100% and providing a deep black color with improved shine and better hair quality.

Its benefits:
- Complete coverage for white or gray hair
Deep, glossy black color that lasts
- It improves hair quality, making it softer and healthier due to natural oils.
- A formula that is gentle on the scalp thanks to the absence of ammonia and a less intense scent compared to traditional dyes.

Suitable for:
- Natural or previously colored hair that needs complete gray coverage
- People who prefer a deep, natural black color with a base, without using ammonia.
Suitable for those with a sensitive scalp or who cannot tolerate the strong smell of dyes.
- It may not be suitable if the hair is very light and you want a significant lightening, as the dye only lightens by one or two shades from the natural color.
