Garnier Hair Color Olia Ammonia-Free Brilliant Color Oil-Rich Permanent Hair Dye, 6.0 Light Brown, 1 Count (Packaging May Vary)

I’ve tried many different hair dyes over the years, but Garnier Olia really stands out. It gave me around 80% gray coverage, which is impressive. Since it has no harsh chemicals, it felt very gentle on my hair and scalp. The application process was super easy and straightforward. I'm definitely staying with this product! 6.0, light Brown I recommend this product

Covers all my grey. It’s gentle and doesn’t have much smell. Pricing is fair. Leaves my hair shiny and very natural looking. I use the light brown and it gives me light brown with lovely natural looking golden blonde streaks when I go out in the sunshine. It’s the only hair dye I will use.

Used it 2 mths ago and no need to dye again, yet. No terrible smell, no ammonia and it is easy to use.

I switched to Garnier Olia after being a loyal Revlon ColorSilk user for years, and I’m so glad I did. I had always used Revlon’s Light Brown because it was ammonia-free and gave me reliable results. Recently, however, I started noticing an unwanted reddish tone developing, even though I hadn’t changed anything in my routine. Since I had been coloring my hair the same way for years, I can only assume the formula may have changed. I specifically wanted another ammonia-free option, so after reading the strong reviews for Garnier Olia, I decided to try the Light Brown shade. For reference, my natural hair is dark brown with some gray, and it had been about 3 months since my last color. Because of the regrowth, I chose to follow the touch-up directions instead of applying it to my full head right away. I left the color on my roots for 20 minutes, then pulled it through the ends for about 7 additional minutes. The instructions suggest 10 minutes on the ends, but I shortened it slightly because I was concerned my previously colored ends might absorb too much pigment. The formula itself was excellent—rich, creamy, and very easy to apply without dripping. It starts out white and gradually changes as it processes. The results were exactly what I hoped for: a beautiful soft light-to-medium brown with subtle dimension and highlighted tones, and most importantly, no red cast at all. It covered my grays nicely, blended beautifully with my natural color, and left my hair looking soft and healthy. While it does cost a bit more than Revlon, the improved tone and overall result make it absolutely worth it for me. I’ll definitely continue using Garnier Olia.

I found this dye easy to use with good instructions. I was concerned that there would not be enough dye to cover my shoulder length thick hair, but it did. I chose it as it was one recommended for grey coverage. I don't have a lot of grey, but it is stubborn! I did put a lot around my temples and hair line (twice), however I can still see a bit of grey. Considering what a mess my hair was before this, I am pleased with the colour (I went darker to cover all the colours I had going on).
