Garnier Olia Gold 9.30 is a no-ammonia permanent hair dye that combines 60% oil-powered formula with natural flower oils, ensuring up to 100% grey coverage and enhancing hair quality for a shinier, healthier look. The unique non-drip texture and floral scent make at-home application a breeze, while being cruelty-free adds to its appeal.
Really easy to use, doesn't drip & doesn't have the horrible ammonia smell. Covers greys really well (they will always be a slightly different colour to the rest on dark hair!) and doesn't fade as much as others. It does give a lovely, shiny, natural looking colour.It does go on a little darker than I expect, however, it lightens after a couple of washes.I have really long, fine hair & 1 box is more than enough for me.Only thing I don't like is the conditioner - it works OK & smells lovely, but I don't think it conditions any where near as well as my usual one, and then I end up with a tube I don't want - would be nice to have the option to not have it

Fun experimenting in lockdown!
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).

Natural color, odorless
It did its purpose. It covered most of the grey hair within 30minutes. It gave the natural dark brown color. The dye was pleasantly odorless, with no harsh ammonia scent

Beautiful colour and so soft
Love the colour, great cover for blond, my hair was dark brown which I bleached and it was still slightly orange after toner which this didn't cover but does warn off that in description, I'm going to get my hair cut anyway so very glad I bought this

Amazing!
I ordered the B+++ maximum bleach as it has no ammonia and I've previously had reactions / anaphylaxis after using another brand eith ammonia. This lifted my hair from dark brown to platinum blonde much better than the brand I used to use, no harsh smell, no reactions, hair still feels healthy. Highly recommend!
