Very watery, but great coverage

4 years ago

[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.

Nutrisse Hair Colour

4 years ago

[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.

Great

a year ago

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.

Works well

4 years ago

[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.

Full grey coverage

4 years ago

[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.

Glossy locks

4 years ago

[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.

Pleasnatly surprised!

4 years ago

[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.

Yes, I recommend this product.

Grey roots to black roots

4 years ago

[This review was collected as part of a promotion.] Due to the limited time frame I had, I decided to colour only the front area as there are quite a lot grey hair. Firstly, easy to apply, no clogging. The smell is similar to other hair dyes too, My hair is thick wavy hair, used to be natural black. I wanted to hide my greys, so was using this product. After applying I waited 30 minutes and washed using my regular shampoo. My hair looks natural black than dyed black which was a plus point. I am unable to mention how long the colour will stay on. I hope it will stay for long time.

Yes, I recommend this product.

The deepest, darkest colour!

4 years ago

[This review was collected as part of a promotion.] First off the instructions are clear (lots of pictures) and the product itself actually smells lovely compared to other hair dyes I've used which have have a chemical smell. No tingling or burning (which is always a plus!) and washed out really well without dying my bathtub black! The colour is beautiful; really deep and vibrant. My hair is very long so I used two packs to cover right to the ends. Definitely recommend, even to first-time box dye users, as it is really simple and definitely cares for your hair - doesn't dry it out.

Yes, I recommend this product.

Something Different

3 years ago

I used the same hair dye for years but was forced to look at new options when I had a reaction to it (yes, it really can happen, even if you've used it a hundred times before). I wouldn't have switched otherwise and that would have been a real shame as Nutrisse Creme seems a much more gentle formula. It leaves my hair soft and shiny while my previous colourant always left my hair feeling very dry and straw-like. The coverage is excellent and my hair is noticeably shiny. I genuinely do find this formula to be deeply nourishing.

Yes, I recommend this product.

I recently used Garnier Nutrisse Crème in Black, and I'm really impressed with the results! The application was easy, and the creamy formula spread smoothly through my hair. It provided excellent coverage, even on my grays, and left my hair looking shiny and vibrant. I also love that it contains nourishing ingredients like avocado oil, which helped keep my hair feeling soft and healthy after dyeing. Overall, it's a fantastic product for anyone looking to achieve a rich, black color with great care for their hair!

Yes, I recommend this product.

Silky smooth and shiny hair

4 years ago

[This review was collected as part of a promotion.] This has such a lovely scent, it doesn’t have that hair dye odour at all. My hair is super shiny, smooth and the colour is lovely. I highly recommend this to anyone looking for a hair dye that doesn’t destroy your hair. It’s also a thicker formula than other dyes so even my husband is happy as it didn’t make a mess. My hair feels soft and looks very healthy. I have already recommended this to family and work colleagues who commented on how nice my hair looks. I will be using Garnier Nutrisse Crème from now on.

Yes, I recommend this product.

Garnier Black Hair Dye

2 years ago

After experimenting with a number of other permanent hair colourants, I settled on the shade Natural Black and wouldn’t use anything else. Every time, this has amazing colour and shine, and people ask me if it’s natural or what product I use. It’s very simple to use, neat, and doesn’t appear to stain. If you like a natural black tone with a gorgeous shine—not matt, dry, gothic black—with an easy application, I can’t recommend this product highly enough! It’s fade resistant and d feels nice on my hair.

Yes, I recommend this product.

Rich Colour That Lasts

4 months ago

I've used this hair dye a few times and it's always given me a rich, even black colour. It covers greys really well and leaves my hair looking shiny rather than dry. The conditioner included is lovely and helps keep my hair feeling soft after colouring. The instructions are easy to follow, so the whole process is straightforward. The colour lasts well before needing to touch up the roots. Overall, it's a reliable hair dye that gives consistent results and is one I'd happily buy again.

Yes, I recommend this product.

Nice deep colour

7 years ago

[This review was collected as part of a promotion.] This hair dye is easy to use. The instructions are easy to follow. The dye itself does not have that nasty ammonia smell which is great. The colour is really deep and dark and gets rid of any grey hairs. After using, hair feels nice and soft and not dried out or damaged. If your looking for a really dark black then this is the colour you need. I used it over a dark brown hair colour and it worked perfectly fine. Looks natural too. Would definitely recommend this black hair dye.

Yes, I recommend this product.

Lasting and leaves hair in good condition

2 years ago

I’ve used this product for the past few years and is my go to for black hair dye. Although I can’t say on the effectiveness on grey hairs I buy this because it leaves your hair in excellent condition even after dying!! The smell of the dye is not very strong either with is great. Gives you a nice natural black hair colour without hints of blue but still being dark. It’s very long lasting and doesn’t fade much at all, even without using colour safe hair products.

Yes, I recommend this product.

[This review was collected as part of a promotion.] The olia hair dye is so easy to use because of the informative instruction leaflet included and the steps to follow. Wearing the gloves provided and mixing the product in the bottle, applying the hair dye is hassle-free. It was washes out of the hair excellently and the conditioner provided leaves the hair feeling soft and smooth. The colour looks multi-tonal instead of looking flat helping it look really natural! Highly Recommended!

Hair dye

7 years ago

[This review was collected as part of a promotion.] I used this on the day it arrived . It easy to mix and doesn’t smell strong . One box is enough for my hair as it’s shoulder length. Simple to apply and it didn’t make my head itch or feel sore from using it. Left on for the stated time of 30 mins . It didn’t drip or run , it’s thick . Washed out and the conditioner makes your hair feel soft and easy to style. Great cover I will definitely use this colour again

leaves hair greasy

2 years ago

This black is one of the darkest blacks I've come across with neutral undertones (no purple, blue or red). Application is a brease like normal, still with it's amazing scent. Once I wash it out and my hair is dried its wet with grease. I tend to not wash it out for 2-3 days as I want the hair dye to penetrant my hair. It being wet with grease is very unpleasant but if you want the blackist black it's worthit.

Yes, I recommend this product.

[This review was collected as part of a promotion.] I find that with some Black Hair dyes that sometimes they look very dark and they look very artificial. This hair dye is the complete opposite of those hair dyes which dry your hair out , with 60 % oils , this leaves your hair with a natural shine which makes it extremely hard to tell that you have dyed it . The dye coats your hair easily and is extremely easy to apply as well.

Yes, I recommend this product.

I have been using Garnier Nutrisse Crème Black for the second time, and I am pleased with how it dyes my hair. It left my hair smooth and shiny, and I really love the conditioner that comes with it. I wish they would sell the conditioner in a bottle so that I could use it all the time. I would recommend this product to anyone who enjoys a bold look with black hair.

Black

6 years ago

[This review was collected as part of a promotion.] This colour came through as it appears on the packaging. I'm dark brown so the finish was exactly as expected, it was easy to apply, felt good and looked great once my hair was washed and styled. It's still as dark now as when it was first done, so there is very little fade and only my roots slightly showing with natural growth rather than colour difference.

Yes, I recommend this product.

[This review was collected as part of a promotion.] This hair colour is brilliant, it really does colour your hair and gives it a really good natural colour, of your choice, too. I would highly recommend this product. It is not as cheap as the other hair colours in price, but, you do get what you pay for, which is value for money, a great hair colour and your hair is left really soft and smells nice too.

[This review was collected as part of a promotion.] The Garnier Nutrisse Creme was easy to use and simple easy to apply. I have a lot of grey hair around the side of my face and back with a few strands of long gray hair. Using this hair colour has left my hair feeling lovely and smooth. I can't seem to find a grey hair at all. I can't wait to use the second box, hopefully not too soon in about 8 weeks.
