Garnier Olia Permanent Hair Dye, No Ammonia, Full Grey Coverage, Long-lasting Colour & Shine, Vegan Formula, Colour: 7.0 Dark Blonde, 230g

I’ve been using Garnier Olia for a while now, and it’s become my go-to hair dye. It’s super easy to use, and I love that it doesn’t damage my hair, even though I touch up my roots about once a month.It also covers grey hair really well, which is a big plus. The color applies evenly and leaves my hair feeling soft and healthy. Definitely one of the best at-home dyes I’ve tried.

This was the first time I dyed my hair and I made the brave decision to do it myself (as I was bored during Lockdown).It was really simple, easy to mix and apply on the hair. It comes with the instructions and you can just follow that.I actually wanted a subtle balayage finish and therefore didn’t use the bottle provided. I instead had a mixing bowl and a brush and cut up some foil to replicate what they do at salons. There’s a lot of YouTube videos that you can find that do just that. I watched a lot of different ones, and for my hair type before doing it myself. I definitely recommend checking them out if your not experienced in dying your hair.As for the result, I was quite happy. Firstly because I have very dark brown hair (almost looks black), it’s the darkest shade you can have, so I knew seeing any colour without bleach/lightning would be close to impossible. I therefore just wanted to experiment with a colour that was very bright and just on the ends of my hair. (So if it did look awful I could just chop the ends off).The first time I attempted it, the colour came out brown, and looked lighter in some shades of light but it was difficult to catch on camera. Sometimes there was shades of red and purple. It basically changed everyday, getting lighter.I wanted to see more result and therefore bought another box, and repeated the process. This time the result was noticeable in any light. I achieved a brown/ginger red tone to my ends. I was happy with this, the technique I used also made sure it was a gradual blend upwards so it didn’t look bad.I also have curly/wavy, hair so it’s easier to cover up mistakes then on straight hair.My hair is thick so I needed more product and bought more boxes. I used three in total, two in on go and one just by itself.The second time I left it longer than recommended and that worked on my hair a lot better.I think it’s best to just rinse and dry one piece of hair and see if the colours shows as you want it, if not then leave it for longer.I also wanted to really experiment with this colour and see what it would look like on my roots (I definitely don’t recommend anyone to try this), but I ended up with hot roots. (It’s not the fault of the product, but just something I wanted to try to see how the colour would look on me if I had lighter hair).I’ve bought this brought in 5.3 in golden brown too, to complete the balayage look. (It was the same price at Tesco).In all I’m very happy with the product and the experimenting was fun.Pros:- No smell of dye- Easy application- Quick results- Lots of colours to pick from- Good price- Decent size (unless u have long thick hair, you’ll need more).- Long lasting colourCons:- My hair became very dry gradually. You have to keep on top of conditioning your hair and use hair serums and oils to keep the smoothness. I have frizzy hair and I needed to do more caring for my hair afterwards. Although the immediate result will give you very smooth shiny hair, after 5-6 washes it became dry. There is however enough conditioner to last you a while. Just don’t forget to use it.- ALERT: Does not cover greys ! (I have a couple greys it did not cover them, it did however colour my brown hair).

Great product, lovely colour, my wife love it

This was an alternative to garner honey blonde which was out of stock.seems ok after first try.

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.

Very good quality colour which provides adequate cover and a lovely tone. I do find the colour darker than expected but that may be down to the quality of my hair and I am sure over time this will fade down. I have shoulder length hair and had to buy two boxes for sufficient coverage but this provided an even more coated application. Highly recommend this product and will buy again in the future

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

Easy to use, good colour coverage.
