It immediately enhanced the color, left the hair very shiny and soft. As stated in the instructions on the packaging, apply to dry hair for intense color. Definitely use gloves.

I use the shade Naranja for an intense copper-orange color.
ATTENTION. Do not follow the instructions of the stores that sell it and say to apply on wet hair.
ON WET HAIR FOR 5-10 MINUTES, THE COLOR WILL BE SOFTER AND LAST LESS.
ON DRY HAIR FOR 10-20 MINUTES, THE COLOR WILL BE VERY INTENSE.
These are the instructions given by the company Nirvel and personally I am very satisfied!

I used the black mask and personally it didn't work for me, and I tried it several times following the instructions, it didn't refresh the color and also stains worse than regular dye :/

I have been using it for 10 years. With all the shades I have tried, I was satisfied and they left the color refreshed and my hair soft and light. I think most people who have left negative comments do not know exactly what this product is and do not know how to use it properly. This product is a color mask. It is NOT a dye. I wouldn't even call it a semi-permanent dye. It is for refreshing color on hair that has already been bleached and dyed. And no, you do not need to rinse it out with shampoo afterwards lol

Throwing away money. A simple good conditioner, it doesn't leave any color at all. For color refresh on copper hair, prefer the corresponding products from Wella/Leganza.

Nirvel top quality!!!! As long as I had my hair fuchsia, it helped me a lot to maintain the color I wanted! Of course, after many repetitions, the expected result is not there, the color changes, I would say it darkens and needs re-bleaching.
I recommend it!!!

I tried the red shade on already red hair and after application my hair was greasy and felt very bad even though I washed it properly. As for the shade, I didn't like it.

Having red hair for years, I wanted to try turning it violet and bought this specific color. It stained all my white shirts (with dry hair) and in order to achieve a nice and rich color, my hair had to be very faded! Very good root coverage but on the third wash (and I mean a lot), the color didn't stay overall! Definitely gloves and it also stained all the white parts of the shower

Update 11/05/2025:
Beware of the shade "copper," they have lightened it a lot and it's okay for very light copper, but not for the classic copper. I used it previously for a year on red/copper light hair and the result was amazing. I bought it again this year for the same purpose and it's barely noticeable that it was applied, it's too light and doesn't take at all.

The only dye that kept the pink in highlighted hair for more than 2 months (washing twice a week).

It is the second nirvel product that I purchase and I am looking forward to trying the rest of the shades. Very satisfied with the copper and strawberry on a copper base, long-lasting color, lasts at least for 8-10 washes. Value for money because even though it is 200ml, it does not require a large quantity and does not dry out the hair!

I left it on for 15 minutes, on blonde hair with highlights. The highlights turned out better than the rest, although it is much darker than turquoise. Generally, it does not easily come off blonde hair, I needed a decapage to lighten it to blue. As a hydrating mask, it does nothing, the 15 minutes I left it on my hair dried it out and I applied another mask afterwards.

I dye my hair in multiple colors for years, when I had them blue, maybe with this dye I could have gone 6 months without re-dyeing them because it soaked so well (always on bleached hair) (I have tried almost all the blues, my favorite is klein blue and blackberry which is dark purple and fades to blue) and the red is a vibrant color (see Para5 Aggela), the plain purple is very nice as a mixer in others and the fuchsia stands out from a distance. Fully satisfied. I use it like regular dye (clean dry hair, for at least 45 minutes, personally I leave it for 1.5+ hours)

I bought the beige color of the sand to maintain the color I had, which was dark blonde-beige, and ended up with copper hair. I don't know about the other shades, but it was really bad. I washed it 5 times in the same day to get rid of it, and it reluctantly faded away, but I had to dye it again

As a shade, it was exactly what I wanted, dark purple. It accentuated the faded color of my hair very well. The scent is relatively good, not exceptional, I would say it's tolerable. I didn't expect it to cover the white hairs since that's not its job, but if they are passed until the next wash, they will have taken on color. It doesn't leave the hair very soft, but it doesn't dry them out either. I had previously used a different brand and it made them very harsh, for example.

The blue is perfect and long-lasting, it just needs a very light blonde, like a level 9-10, otherwise it turns out to be a greenish-blue which is not bad

Hey guys, the mask is of pretty good quality. I used it to dye my entire hair, but I got worried because it's the 6th time I wash my hair and the color is still very intense, as if it will never fade away...

It is an awesome product that I have loved from the first moment! It moisturizes and leaves the hair silky, with perfect shine! Since I discovered it, it is never missing from my house! I have blonde dyed hair and I love the sandy finish, this mask always helps me achieve what I want. Compared to silver shampoos, it does not leave the hair purple if you leave it on for a little longer, it may just darken it, but that is fixed in the next washes. The only thing one should be careful with is the application, it requires very good spreading (I comb it very meticulously with a comb) to go everywhere and evenly capture the color. It has a very good duration, better than the toner. If I leave it on for a little longer, yes, it will darken but the result will last longer, I see it as a change!

It is 2 tones definitely darker than what it shows, but it can be corrected when combined with a mask. It has a strong effect. Quite satisfied with the purchase.

Very good result and fast without altering the hair while I had very damaged hair, you should try it

I bought the shade copper and I can't say that I was satisfied, it is more red than copper. I don't know about the other shades, maybe they work better there. However, if you have copper hair, it is definitely not a good choice. There is a high chance that it will ruin your color.

I had used the red color since I am a redhead. Very good performance for refreshing your color. After shampooing, I would towel dry my hair and leave it on for about ten minutes or more. It leaves a very good feeling on the hair. I can't understand how it wouldn't perform well on the hair, it must be used incorrectly somehow. I would definitely buy it again, and it had lasted me about 2 months. Very good for its price!

I wanted to ask those who have bought it, is the color very dark? It says bubblegum, but the inside is very dark

no result in color only left my hair soft like a regular conditioner. luckily someone gave it to me who didn't want it because otherwise I would cry my money. a similar product from a Greek company did an amazing job on my hair.

In dyed fuchsia hair, the fuschia shade is simply fantastic! It refreshes and enhances the color a lot! The color gradually fades with washes.. I buy it again and again!

I have used it on the blonde ends of my hair when I had highlights. At first, I mixed a small amount with a white mask to achieve a softer pink result. I have also tried it on its own. It left me very satisfied. The color lasts and it is worth the price, both in terms of quality and quantity, especially if you mix it with another white mask.

Excellent hair mask, I highly recommend it!! Large quantity, no comparison with similar ones, for my medium-length hair it lasted for over a month as it has very good durability and does not need to be renewed after every wash. It has amazing pigment in almost all colors, to the point where it requires caution if you don't want intense results (you can mix it with a plain mask or shampoo to make it softer). The silver shade is an exception, it only works on white hair, giving them a more silver tone (mine have a level 9-10 lightening and it didn't work, but it worked on a friend with WHITE hair). The gray shade is particularly dark with many blue pigments. Personally, in order to not lighten my hair too much and prevent them from turning green (blue + yellow from bleaching = green), I use the gray shade together with pastel pink and mixed with silver or plain mask!

This specific shade only works well on very light blonde hair. The result is pleasant both in terms of color and feeling because it deeply moisturizes. I recommend applying it strand by strand, taking generous amounts on dry hair and dividing it into sections, waiting for each section for 20 minutes. Rinse out each section and wash at the end.
