Garnier Olia 1.0 Night Black: 100% Grey Coverage. No Ammonia, Oil-Powered for Luminous, Long-Lasting, Vibrant Hair Color.

Arrived on time. We'll packaged. Beautiful colour. Being Asian and naturally having dark brown/blacky hair this was not the usual shocking pitch black dye, like most 'black' hair dyes. Wonderful conditioner included lasted a few washes after. Will buy more. Stains skinsonewhat but can overcome by applying a bit if Vaseline around forehead n ears etc but nonetheless it fades after a few washes.

I had to write a review. I have damaged hair which was also looking a bit tangoed from bleach and semi permanent attempts which failed. I am also going through the menopause so my hair is no longer thick. I have been scared to used color on my hair feeling it will make it worse. This must be the best hair dye I have ever used, what hair dye improved the quality of your hair, this one did. My hair is so soft and less brittle. I used Ice Brown, beautiful color. Definitely will be only using this brand in the future and recommend.

Super easy to use and completely ammonia-free, which made the process much more pleasant. The cream formula didn’t drip, and I got beautiful, natural-looking balayage in under an hour. My hair felt soft and shiny afterward, not dry or brittle. Great value and cruelty-free too – I’ll definitely buy again!

I really want to like this hair dye, the colour is great and leaves hair really shiny. It smells so much better than other dyes and the conditioner is lovely. However it didn’t last very long and within about two weeks grey hairs where coming back

Really good hair dye. I would say it is not as thick in consistency as other products but I felt it lasted longer and made my hair feel really silky smooth.To apply is very easy and I like the black gloves they provide. I also found the conditioner provided is really good for your hair but it smells like the hair dye.

Really good colour been using it for a long time. Easy to use and hair is lovely and soft.

I've used Garnier Olia in shade 112 Super Light Beige Blonde and overall, I'm quite pleased with the results. It provides excellent grey coverage and the colour turns out natural-looking and even. One of the things I appreciate most is that it's ammonia-free and contains 60% oils, which makes it much gentler on the hair compared to many other permanent dyes.My hair didn’t feel dry or overly damaged after colouring, which is a big plus. However, I did notice that the finish isn’t as shiny as I’ve experienced with some other products. While the colour is nice, it lacks that glossy, salon-like shine.That said, for an at-home dye that covers greys well and is less damaging, this is still a great option, especially if you prioritise hair health

My previous colour:Before I dyed it, my hair had a few inches of my natural dark brown colour and the rest, past my shoulders was a very light gingery brown with some of the ends so white they almost were see-through.Was there enough dye for even coverage?I got two boxes to be safe. I have very thick curly afro 3c/4a hair that is touching my shoulder blades when stretched and had to use one box per side of my head. It was only just enough to do my whole head but everyone is different. I recently used Garnier Olia in a red shade to dye my caucasian friend's straight hair which is way past her shoulders and one box was just enough for the entire head. If you aren't sure, always get an extra one at the ready otherwise you may end up with a patchy colour.The colour/result:Overall, I was very pleased. I was looking for a brown as dark as possible without going black because black looks very fake on my skin-tone. The colour did come out black like some reviewers on other sites like Boots pointed out, but I'm still happy because I knew what I was signing up for and know it will fade over time and I wanted it as dark as possible initially. Under bright lights it does look dark brown, otherwise it looks very black. But I'm happy because it is incredibly shiny and looks healthier than it did before. This was my main reason for attempting to go back to my natural colour, though my hair is healthy, the light colour was making my hair look thinner and drier than it was.Further comments:I highly recommend not using the bottle they give you. Other reviews have pointed out it is a very cute tear drop design but incredibly hard to hold. It wouldn't say it was that hard but it definitely doesn't help when you're trying to move quickly and not drop dye everywhere. Use the gloves and apply it by hand or with a tint brush after pouring it into a hair dye mixing bowl (or one you don't mind staining). This way you can get every last drop and it is very easy to apply. It did get on my shoulders and back but came right off when I had a shower, I got a tiny drop on one of my painted walls and it isn't coming off but I have done this before and it does fade completely over time if you wipe it off the minute you get it on there.Would I recommend it?In short, yes. It smells significantly nicer than any other dye I've used before which smell strongly of ammonia. If you're particularly sensitive to those scents I definitely recommend the dye for this. It took to my whole head, even though my colour was very uneven before I dyed it, the dye gave an even shade all over without looking fake or blocky. But I'd warn that if you're looking for something make your hair dark brown, you might want to go a shade lighter otherwise you're going to get black.
