Very watery, but great coverage

[This review was collected as part of a promotion.] I found the instructions easy to follow. After mixing the products I found that it was a very watery consistency, which was quite difficult to work with and keep mess free. However the dye did wash off my skin quite well. I like how much of the packaging was recyclable, that's definitely a bonus.
The smell of the dye wasn't overpowering, and it smelled quite natural. After rinsing it took a while for the water to run clear. The conditioner was very pleasant. All of my greys are covered and my hair is a lovely, glossy black colour. I used 2 bottles as I have rather long hair, but being naturally dark haired I probably could have got away with 1.
Yes, I recommend this product.

[This review was collected as part of a promotion.] I guess it does what it says on the box - colours your hair and gets rid of the grey :)
I did leave it on slightly longer than I should have, but the reason I did this was due to the stubborn grey hairs on my hairline near my ear. Unfortunately my face got covered too, but I suspect this will fade . I did use some baby oil to try and remove some staining. Overall, the hair colour was good to use, no heavy/strong smell - it was pleasant enough for me to be able to do some household chores whilst waiting for the colour to develope. I used some of the conditioner after washing my hair. I normally let my hair air-dry, so far so good.
Yes, I recommend this product.

Review of Garnier Nutrisse Crème Hair Dye:
Garnier Nutrisse Crème is a fantastic choice for at-home hair coloring. It provides rich, vibrant, and long-lasting color while nourishing your hair with its creamy formula enriched with avocado, olive, and shea oils. The conditioner included in the kit leaves hair feeling soft and healthy after coloring. One of its best features is the ability to cover greys effectively, giving a natural and even tone.
Although it is generally easy to apply, the cream formula can feel a bit thick for some users. Overall, it’s a reliable and affordable option for those looking to refresh their look without compromising on hair health.
Yes, I recommend this product.

[This review was collected as part of a promotion.] This isn't my usual brand but I was happy to try something new. I found the instructions easy to follow and the dye was easy to apply to my hair, and definitely smelt nicer than some others I've tried in the past. The colour looks natural on my hair and matches the existing colour lower down from the roots, so blends in well. I've not had long to test this so can't comment on how well the colour stays on my hair after washing etc. but I'm happy with the immediate colour result and the process of applying it etc. Assuming there are no issues with fading or washing out, I would be happy to use this product again.
Yes, I recommend this product.

[This review was collected as part of a promotion.] The instructions are really easy to follow and I loved that they had which elements could be recycled. The gloves were long which stopped accidentally splashing my wrists which I tend to do on occasion.
I was surprised at how much dye and lotion there was, usually I am scrapping the sides trying to get that last bit covered, although I usually only top up my roots.
Application was really easy, I expected it to be runny but it went on easily.
I loved that you got a conditioner! And that it lasts more than one wash so my hair can feel this soft and smell this good for longer.
Yes, I recommend this product.

[This review was collected as part of a promotion.] This product is super easy to use. The quality of the gloves included it’s definitely above average I normally put my hands straight through them. The conditioner bottle is huge must have over 6 applications in. Very unusual to have one so big. The product gave my dry getting hair a glossy boost. My normal brand tends to dry my hair out but I was surprised to find how well nourished it looked. Very shiny and I only used a little bit of the conditioner. Great grey coverage too, those pesky greys were well and truly out in force this blended nicely to give excellent overall coverage.
Yes, I recommend this product.

[This review was collected as part of a promotion.] Gosh i cant remember for how long i've used hair dyes!!!!! i have grey roots so tend to dye those mainly. i always use the same brand but always open to try others. it was easy to prepare, no overpowering smells & easy to apply. After rinsing i boted just how soft my hair felt especially after the conditioner. once dried as my title suggests i was pleasantly surprised. it gave great coverage and didnt seem quite as harsh as my previous dyes. i wear my hair up mostly so you can always see the grey roots if the coverage is not great. no grey roots with this one. the only thing i would say is that the dye around the hairline was really noticeable and difficult to get off, i know this fades after a couple of days but it was really noticeable.
