Garnier Olia Hair Color, Ammonia-Free Permanent Hair Dye, Oil-Powered Formula for 100% Gray Coverage and 3x Shinier Hair, Vegan & Cruelty Free, 1.0 Black, 2 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 was pretty hesitant to buy this after reading some of the negative reviews. But let me just start by saying that for me this worked great. I know a lot of the reviewers below say that they are experienced with home haircolor. But keep in mind that a lot of the yellow-haired women walking around Walmart in house slippers are also very experienced at doing an awful job with their home haircolor and they think it looks great. I really am comfortable in saying that I am experienced with home haircolor. I've dyed my hair at home since I was 13. My natural hair color is a dark ash blonde/borderline very light mousy brown. Most home blonde hair dyes turn that hair color bright orange. Before olia, the only ones that could turn my hair a pretty blonde did so by frying the crap out of it with bleach. I'd like to point out that, no offense to women who dye their hair red, brown, or black, but it requires much more skill and better quality hair dye to go from brown to a pretty blonde. This dye did great though. Regarding texture, my hair is naturally a bit coarse and dry. I am one of those people who can wash her hair every other day instead of every day. So when I heard that olia was oil-based I thought I would give it a try. I used two colors because I always do highlights and low lights in my hair (this looks more natural, high end, and flattering) For the low lights, I chose olia 8.0 a medium blonde. For the highlights, I chose olia 9 1/2 .1, the lightest ash blonde. I use a bowl with two divided sides (One for each color) rather than the bottles that actually come with this hair dye. So, I cannot comment on how easy or hard the bottle is to hold throughout the application process. I thought I should note that because some of the reviews below do mention that it is difficult for them to hold onto. I also don't use gloves. I need to be able to feel with my fingers which parts of my hair are wet with dye and which are not. I put the two colors on in 0.5 to 1 cm increments and left it on for about 25 minutes. I did sit under the hair dryer on low heat for about five minutes after I went and did some chores around the house. I rinsed it out well in the shower then shampooed any residual dye out with shimmer lights shampoo for blonde and silver by Clairol. I followed it up with the actual Olia conditioner that came with the dye and thought it smelled great. I left it on for three minutes. When I rinsed it out, my hair felt soft and silky. After the shower, I put in some bio silk as I always do and twisted my damp hair up in a towel for 30 minutes to let it rest. After that I blew dry it and curled it was a curling iron like normal. My picture below shows the results and I'm very happy. My hair does not smell like I just dyed it and more importantly it does not feel like I just dyed it but it sure looks like I just dyed it. It's a win-win! For me the benefits greatly outweighed the negative comments below. I got very good color that made my hair actually feel soft and was very affordable and convenient. Negative comments about Gloves and bottles shouldn't sway your decision to try this. I've already ordered these two colors again so that they'll be ready when my roots start to come back. I hope they never quit making this hair dye.

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.

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 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.

Been using this for many years. No issues and while I would say it covers those odd stray grays, it doesnt cover areas that are sold gray like the ones that frame my face. I still use it and just tell people I left the gray temple area on purpose. LOL. Your hair feels good afterwards although I never liked the fact that you aren’t supposed to use shampoo to rinse out the chemicals, just water. The smell is not overwhelming however I did recently stop using the conditioner that comes with because the fragrance just started to bother me. Still, not a bad smell I just didnt like it anymore.

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.

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.

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.
