Garnier Hair Color Olia Ammonia-Free Brilliant Color Oil-Rich Permanent Hair Dye, 9 1/2.1 Lightest Ash Blonde, 1 Count (Packaging May Vary)

Man-Approved! ​As a guy who colors his hair, Garnier Olia is the best product out there, hands down. My main issue with other dyes was that stinging, brutal ammonia smell—this one is ammonia-free and has a subtle, clean scent that makes the whole process tolerable. ​The oil-powered formula is great; it doesn't leave my short hair feeling dried out or brittle. The color is rich, lasts well, and the application is straightforward and non-messy. I get excellent gray coverage without the typical harshness. ​If you’re a man looking for a high-quality, gentle dye that just works and doesn't smell like a chemistry lab, Olia is the answer. Highly recommend!

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.

I was getting skeptical when I saw the dye looking watery and orange looking. But it left my hair red like it was supposed to! Left it soft and smelling amazing. Hopefully it lasts long but overall loved it 🥰

I’ve been using Garnier Olia 1.0 Black for over six years now, and it’s one of the few permanent hair dyes I keep coming back to. The biggest reason is that it’s ammonia‑free, which makes it much gentler than many other options I’ve tried. It doesn’t have that harsh, eye‑watering chemical smell, and it feels far less irritating on my scalp during application. The application process is straightforward—mix the colorant with the developer, shake well, and apply first to the roots, then through the lengths. The included gloves and conditioner make it easy to do everything at home without extra tools. The formula, powered by oils like sunflower and camellia, spreads smoothly and feels more nourishing than standard dyes. Color‑wise, the shade is a rich, deep black with natural reflects. It provides full gray coverage and makes my hair look healthy and shiny right after coloring. That said, one trade‑off I’ve noticed over the years—and something others mention in reviews—is that it does fade faster than some ammonia‑based dyes. The vibrancy starts to soften after a few weeks, especially with frequent washing. On the plus side, even as it fades, it does so evenly without leaving patchy tones. My hair always feels soft and manageable afterward, with no straw‑like dryness that some dyes can cause. Being vegan and free of silicones, parabens, and phthalates is another bonus for me, as I prefer formulas with fewer harsh additives. Overall, while the color longevity could be better, the comfort, gentleness, and healthy feel it leaves in my hair make it worth sticking with. For anyone who wants a rich black shade without the strong odor and irritation that come with ammonia, this is still one of the best options out there.

I tried this product after my original product was hard to find in stores. (Used to use Feria) I like this quality much better. Leave my hair feeling silky rather that stripped & brittle. The color is beautiful. I have never colored my hair in a salon. This product works lovely.

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!

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

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).

satisfaite.
