Garnier Olia Hair Color, Ammonia-Free Permanent Hair Dye, Oil-Powered Formula for 100% Gray Coverage and 3x Shinier Hair, Vegan & Cruelty Free, 3.11 Darkest Platinum Brown, 1 Count

UPDATED PHOTO . . . LASTS FOR AS LONG AS YOU MAINTAIN IT. This product will still be my go-to for at least the next year or so, but it does wash out if you don't maintain it properly. After the first 3 cold water washes with a minimal amount of Four Reasons Rose Pink shampooo, it was still pretty vibrant and mostly dark rose. Then I got lazy and washed it in warm water. The rose immediately disappeared, but it turned a really pretty peach color. I used too much Four Reasons Rose Pink to try and get some of the pink back, but it only worked on the brightest parts of my hair (the front money pieces / level 10). It kept the rest of the hair a pretty rose gold, but not anywhere near the original outcome. The last photo is 3 weeks in and after a regular wash without the Four Reasons shampoo. It's pretty much strawberry blonde now. I actually like the different changes it goes through so I'm not changing my overall rating. Just be prepared to either maintain this with super cold water, or be okay with having your hair turn different (but very pretty!) colors before your next dye session. P.S. I washed my hair every other day or every third day. Going forward, I'll probably only wash it once a week and use dry shampoo as needed. ORIG REVIEW: About four months ago, I'd lightened my hair to level 7/8/9 then up to 8/9/10 so I could play around with semi permanent colors. When my level 5 roots started to grow out, I knew I didn't want to keep bleaching, so I looked for something that might work well to blend my roots and cover my grays while also being bright and fun. I chose Dark Rose Quartz, and I think it turned out really pretty. But you definitely need to lighten if you want it to be dark pink and not dark peach. The parts of my hair that were still a level 8 blonde turned out sort of a peach mauve. For upkeep, I plan to use Four Reasons Rose Pink shampoo to keep the shade from fading, and I know from experience to only wash with cold water. If it fades too quickly, I'll update the review, otherwise, consider it a success on PREVIOUSLY BLEACHED, very porous hair. Virgin hair probably won't look anything like this. If you're a level 10 gray or blonde, expect this to turn bright pink.

I found my first grey hair when I was 17 years old. Used to pull them out and eventually realized that was not a good strategy, LOL. I have been using different hair color products for a very long time. Garnier Olia is a good, subdued, natural looking product with no strong smelling chemicals. I get two uses out of one box, mixing the coloring agent and the neutralizer 50/50, without any issues. I store the remaining coloring agent (in the tube) in the refrigerator until the next use. The product is not watery like some hair color products, which helps greatly in managing its application. .The color truly does last. I buy more Olia hair color ONLY because my hair has grown out. I leave it on 45 minutes, which is a bit longer than directed, just to make sure it takes. Then rinse the chemicals out, saving shampooing my hair until the next day. My preferred color, 6.3 is currently unavailable. I hope this is a temporary hiatus as I'm very happy with it. It's the same color as when I was a little girl, so looks unobtrusive and natural. The only thing I would change are the included gloves. I wish Garnier would include the same large size, but more fitted, similar to medical gloves. Then I could actually feel what I'm doing. Aside from the problematic gloves, I highly recommend Olia hair coloring products.

Been using this for over a year and it looks salon quality at a fraction of the cost! It’s very gentle on my hair due to the no ammonia and it makes my hair glossy. I get so many complements!

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.

Beautiful hair color and lasts quite awhile without fading quickly. Very vibrant and covers well! No issues applying it. Great value for the quality! Definitely purchasing again!

I can only find this hair color on Amazon. I actually buy it to make my hair blonde. It looks a little pink when I first dye for like two days and then it fades to the perfect blonde. I get so many compliments when I use this hair color. It’s my favorite.

Looks good , does the job with coverage immediately after application . I have very grey hair . It covered all of it. But it just doesn’t last long enough on my greys.

Garnier Hair Color Olia is a popular choice for those looking for an ammonia-free hair dye with a focus on nourishing and vibrant results. Here’s a comprehensive review based on its key features and performance: Pros: Ammonia-Free Formula: One of the standout features is that Olia is free from ammonia. This can make the application process more pleasant and less harsh on the hair and scalp. It also helps to reduce the strong chemical smell often associated with hair dyes. Oil-Rich Formula: The dye is infused with natural oils (like flower oils), which help to nourish and condition the hair during the coloring process. This can leave hair feeling softer and looking shinier compared to some other dyes that can be drying. Rich, Long-Lasting Color: Many users report that the color results are vibrant and long-lasting. The dye is designed to penetrate deeply into the hair fiber, which helps the color to stay true and not fade quickly. Pleasant Scent: Compared to traditional hair dyes, the scent of Olia is generally considered to be more pleasant, likely due to the absence of ammonia. Wide Range of Shades: Garnier Olia offers a broad spectrum of shades, from natural to vibrant colors, making it easy to find a hue that suits your preferences. Good Coverage: It provides excellent coverage for gray hair, which is a significant benefit for those looking to cover up grays. Cons: Application: Some users find the application process a bit tricky. The oil-rich formula can be thicker and might not spread as easily as other dyes. This can sometimes make it harder to ensure even application. Development Time: The processing time might be longer compared to some other dyes, which could be a consideration if you’re looking for a quick coloring solution. Color Variability: As with any hair dye, results can vary depending on your starting hair color and type. It’s a good idea to do a strand test before applying the dye to your entire head to ensure you get the desired shade. Price: Garnier Olia can be a bit pricier compared to some drugstore hair dyes. However, the benefits of an ammonia-free formula and nourishing oils might justify the cost for many users. Overall: Garnier Hair Color Olia is a strong contender in the ammonia-free hair dye market. It offers vibrant, long-lasting color while being gentler on the hair thanks to its oil-rich formula. It’s a great choice for those looking to avoid ammonia and who appreciate added conditioning benefits. While the application might require a bit more effort and the price is slightly higher, the results often justify these considerations.

Love this. Have bought more expensive brands before but this is by far the best. Doesn't stain skin as the oil helps wipe. The smell is wonderful. No more nasty, suffocating smells. The color itself is great with warm undertones. I mixed the 4. + 5. and use double size for my very long hair. Perfect 100 Percent gray coverage. Hair feels smooth and silky afwtr washing and smells nice.

Coloured my roots nicely. The product is very thick & I had a slight problem getting all the color out of the bottle but the result is good. Covered the dark hair at the back & grey in the front. I will use this product every time now.

I’ve tried this product before and I love it. This is my perfect colour since I was a kid. I don’t need to colour for about 8 weeks.

Very natural black color, I love it!

This is the best hair colour. I’m a swimmer with very fine hair. The chlorine is really hard on my hair. This is the only hair colour that doesn’t create further destruction. Nice selection of brown colours too, so I was able to get a colour that really suited me.
