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 used Garnier Olia in Darkest Brown, and I’m really happy with the results. The color came out deep and even, with a natural shine that doesn’t look flat or artificial. My hair felt soft and conditioned after dyeing. I wish they sold the conditioner in a separate bottle. Almost worth buying a box of dye just for the sample of conditioner! The application was easy to follow, and the scent was much milder than traditional dyes. Overall, it gave my hair a healthy, vibrant look, and I’d definitely use it again! I had light brown hair to begin with

I tried Garnier Hair Color at home and was mostly satisfied with the results. It’s easy to use - just mix, shake, and apply. Gloves and conditioner is included. I liked that it’s ammonia-free, and my hair felt soft, not dry, after rinsing. I used it to cover greys and it worked well, although it didn't provide good coverage near my temples. The color looked rich and shiny. Overall it’s a gentle option worth considering.

The best do-it-yourself hair coloring. Love the oils. They make your hair so soft and shiny. I'll never use another brand.

Ordered Black 1.0, and it came out just how I wanted. The perfect black, my hair feels healthy still and the shine is beautiful. The box does say that it’s not recommended for highlighted hair, but my hair was lightly highlighted and it covered it perfectly. Also had quite a few grays coming in and I don’t see them now. Just a tip if you’re not familiar with dying your hair yourself, you’re going to want to rinse your hair more than twice in the shower. If it runs clear and you think you’re done, think again. Also another tip: the first time styling your hair, the black will run off on your hands, and possibly your bedsheets or pillowcase. It’s not a defect in the hair dye itself, it’s just a result of dying in your hair black with any brand of hair dye. But I do love it!! I definitely recommend. **UPDATE** Just wanted to update that black has not faded yet, which I have experienced pretty quickly in the past with other dyes. I’ve washed my hair about five times already with color safe shampoo & conditioner, and the color is still vibrant! Updated photo is the one with straight hair.

Leaves my hair soft, color is lower on chemicals, my go to since the color is lovely and the only coloring that actually feels very conditioned and NO dryness after coloring

I’ve been coloring my own hair for about 20 years now and I typically do it every 2-3 weeks. I rotate between the platinum black and regular black colors. I’m naturally blonde so when my roots start to show in the slightest bit I hate it! This stuff is gentle and effective. Covers the gray hairs and makes my hair super soft. I really like the conditioner that comes in the box. No strong smell and the dye is easily removed off the skin.

Don't buy. Did NOT change COLOUR at all, rinsed clear after 40 minutes. Unable to return. Waste of my hard earned money.

Can but in Walmart USA for $10.00. Can’t buy in Canada! Lovely colour, excellent product but very very expensive to buy here! So if you want this product, and you are in Canada you are stuck paying this ridiculous price! I would say gouging! It should be more reasonable priced!

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.

Todo bien

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).
