I was excited to trial this product as I have seen it at the supermarket and was attracted to the packaging and liked that it was ammonia free however I tend to stick with brands that I have used before so had not tried it until now. Dark blonde is the shade that I usually colour my hair and Garnier Olia dark blonde came out the colour that I was expecting. I also liked that there was no harsh smell like many other hair dyes.
I found the box stand idea to be fiddly and in the end I just put the mix up container on the basin bench and I disliked that you had to combine the two colour mixes in a separate container (the home dyes I have used in the past you add one mix to the other) so I felt like this was an extra unneeded step which took more time. Although the applicator container looked really nice I found it hard to grip and it had a sharp part on the nozzle which made it more difficult to apply although the sharp part could have been down to bad luck when I snapped off the seal. I also found the gloves to be on the smaller size, great if you have small hands but if you have big hands like me not ideal.
The colour was quite runny but I did find that it went on quite well (other than the container issues) but if you had long hair you would defiantly need two packets as I have just below shoulder length fine hair and used all of the product up. It didn't cover a couple of grey hairs that I have but to be fair they are quite stubborn and the last hair dye also missed them.
The conditioner was ok. I used quite a bit of it, more than what they suggested but felt like my hair needed the extra. I liked how they provide enough conditioner for a few uses.
For the price I wouldn't use this product again but maybe I would be tempted if it was on sale. Overall it did an ok job, it coloured my hair the shade that I was after but I found it to be more difficult to mix and use than other hair dyes that I have used in the past.
Was not impressed with this product - maximum colour performance - I disagree.. although 9.0 is not my usual colour (I use 10.1 but was sent 9.0) it was very "brassy" . It is definitely hard to find the right blonde.. and all hair colours differently, I would possibly try it one more time to see the outcome with more regrowth. - 100% grey coverage - I don't have any greys so can't comment. - visibly Improves hair quality - as I only died 1cm of regrowth it was hard to tell. My hair did feel silkier after. -optimal scalp comfort - I expected to not get the itch or burn that other hair dyes with ammonia do however I still found this to irritate, it didn't have as strong a smell as others though. The fragrance was nice although I prefer the normal Garnier smell.
I would probably try it one more time to see if I can get the desired colour.
Tips: 1 pack is good for re growth - covers around 10-15cm of hair depending how thick so if doing a full colour Atleast 2 boxes would be needed for a full proper coverage
