Very good product, in the black-blue color that I had dyed my hair for twelve years, it did the job. I needed to do two decapitations, I left it on for half an hour each time, with a difference of six days, and I achieved a copper-red color. I will do a third decapitation because I want to make some highlights in a few tufts, a kind of balayage. The hair was not damaged at all, no dry ends, no frizz. As for the smell of the materials, personally, it didn't bother me at all. For protection and hydration, I applied a little silicone after use. That was all. I recommend it without fear.
I was not satisfied ☹️ Maybe it's because they were dyed black for many months. The color opening is 1-2 shades. That is, it remained dark brown. However, the 2 stars are not for that. They are for this awful smell that won't go away from my head!!! And after 20 days of writing, it still smells bad. It's summer and I shower daily because of the heat. Not to mention that wherever it drips, the whole bathroom smells!!! It needs a thorough cleaning afterward... Be very careful about this. Anyone who can't stand bad smells SHOULD NOT BUY IT!!!
Guys, listen to me. I have tried this product before. My base is dark chestnut. I had made it red and got tired of it and wanted to remove it because it wouldn't fade at all. So these are the results. One use. One could say very good. Then after years I used it again because I have my hair blonde and I thought to put a gray chromomask on it to make it look silver. So guess what came out? Green blue. For months it faded only a bit and I hoped that the blonde would stay at some point but nothing. I used this product from Nirvel and the results were what you see in the photo. I believe it helped quite a bit, there is something grayish left that definitely resembles mint green BUT both times I didn't do a bleaching. My hair was not damaged at all. The smell does indeed make you want to say haha what smells like this but it's bearable since the results are very good.
The good thing is that it doesn't damage the hair. It smells incredibly bad, even the next day my hair smelled. But I didn't get it for the fragrance. It completely removes the color as long as it is freshly dyed; if you have had the color for a while, it requires many applications
It does its job well, from black they turned brown, it reddens a bit but personally it doesn't bother me, the top is a bit lighter, which is logical since they have undergone fewer layers of dye than the bottom which has gone through years of dyeing. A few tips I have to give are not to rush to empty the entire bottles, I who have hair down to my waist (with bangs and layers but still thick long hair) needed a little more than half the amount, be careful not to let it fall on the roots because it slipped on me and burned for a few hours, it didn't cause any damage just felt a burning sensation. Also, it's better not to apply dye immediately even a lighter color because it's likely to darken, it's better to do a color shampoo, a rinse, something light. I didn't do anything, I like the color as it stayed on its own, I'll see how it goes in the next few and probably will do a pass with the leftover product. The scent is not nice but that's the least of it. My hair feels the same as before, I haven't felt it was damaged, as if I haven't done any technical work. A good hydration afterwards and it's just fine.
It does a very good job in opening up from black, even without patches!
It gave me an exceptional golden blonde.... HOWEVER...
The dye I applied afterwards (natural sandy blonde) turned out pitch black... The root clearly came out lighter not because of the product itself, as it doesn't affect it, but because it was uncolored for a long time.
So basically, I went through the trouble and expense to end up looking the same as before...
Plus, it made my hair feel rough as if I had used a decapage. I applied a mask again, but still...
Excellent product. After 2 months of using black permanent box dye, it faded to blonde at the ends and ginger in the middle. The health of my hair remains the same, it has not dried out or broken. I recommend it to those who want to achieve very dark colors. If someone wants to become blonde, they can also do a round of bleaching and they're ready to go
I had it in black, used the product, it opened very nicely to a reddish-brown color, then after two days of dyeing, it turned out very light, as stated in the instructions, and again it came out dark, not black but dark! Let's hope it lightens up! The color lightens, but what's the point if it keeps getting dark again!
It opened to me in black blue 2.1 in light copper but the result was temporary. The hair darkened day by day without doing anything to them. When I dyed them again after days with a 6 color while they had become medium copper, they came out almost black tones 1-2, as other girls write. I do not recommend it, Friday's joy is Monday's sorrow as a product. You get excited with the initial result but gradually it darkens and also, no matter what color you dye it, it comes out black very black.
My hair was a level 9 blonde and I dyed it a level 6 dark brown. I used this product and it quickly showed that it was doing a great job, bringing it back to a level 9 very light yellow-orange blonde. Without going into too much detail, I gave it the recommended time to work and then washed it out. When I came out of the bathroom and looked in the mirror, I was shocked to see that my hair was back to a dark brown level 6!!! I do not recommend it at all! The next day, I tried the "Revolution Hair hair colour remover" and my hair ended up at my desired result, a level 7-8 ginger.
Shock!!! Shock!!! Shock!!!! I had dyed my hair blue black again a month ago as usual.. and within 20 minutes my hair turned out a very nice shade of brownish-red and I will leave it like that without applying any dye!! Later if they fade more then maybe I will get some dye to fix the color!! But they turned out perfect and without many patches even though underneath I had some decapage from highlights but still a very good result!!! Nirvel thank you
Hello, can you tell me why I did it already once and it came out with a nice color, the smell was indeed strong but okay, but as soon as I took a bath, it became dark again. Do I actually need an oxidizer for it to set as they say, immediately after dyeing? Thank you
I have to say that it is excellent! I had put temporary dye gel that comes out with shampoo and it was supposed to be burgundy but it turned out to be fuchsia. I forgot about it while doing chores and it was horrible on silver dyed hair!!!! It saved me, I used it twice in a row and everything is fine!! It smells somewhat strange, truth be told, but it's worth it!
The product does exactly what it describes. Its instructions are detailed and thorough. My natural color is a 3 (dark brown). I have been dyeing it for years with variations of 5 (sometimes warm shades, other times sandy). I have about 40% white hair. After the hairdresser's disastrous attempt to make it chocolate brown at level 6, I bought this product to remove whatever color she applied so that I could dye it myself. And I say "whatever color she applied" because instead of giving me a uniform color from the root, she started playing around, obviously to make me pay more. It should be noted that she was the hairdresser I had been going to for years and she knew exactly what colors and bases she used. Also, I had cut almost half the length of my hair, so it had nothing to do with frayed and faded ends! So, after the shock, I bought this product and I can say that the result was very good. It removed the heavy and dark pigments (because what the hairdresser did to me was not just a level 6, it was much darker than what I wanted!) and left a warm color, a light chocolate with copper tones. A very nice and even base for me to do what I want now. It did not irritate my skin, the quantity, as already mentioned, is sufficient for 2 uses comfortably. The smell is quite strong but manageable. Personally, it did not last on my hair for more than 2-3 days with continuous washing. I have yet to see how it will respond to the new dye. Although my hair did not suffer from the process, I think it's good to wait a few more days before dyeing it with permanent color.
Very good product. I dyed my hair with red hair mask for one and a half year and then used the decolorization once. I left it for about 45 minutes and it showed me the decapage. It didn't damage my hair at all. In the past, I dyed my hair black and when I used Nirvel, it didn't do much work, so I understand that it is effective for hair that already has decapage, otherwise it won't lighten them.
I dyed my hair a week ago and it turned out very dark. I tried the product only on a strand to see if it would have any effect. I am quite satisfied with the result, I will also do the rest of my head :)
It does what it says without damaging the roots. It doesn't smell too bad, just a little. It brought back my medium brown hair to blonde. However, the blonde needed some highlights afterwards because it was quite yellow. Don't dye your hair immediately after using this product because it will return it to its original color. Only use highlights or a gloss if you're satisfied with the color.
The product is fantastic. I had been dyeing my hair black for years and wanted a change without damaging it with bleach. However, because I didn't want to risk the outcome, I purchased the product and had my hairdresser apply it for me, who thought it would be good for me to sit under the heat for 5 minutes to help with the process. The result is perfect. My hair has turned a vibrant red without any additional dye being used!!
I was shocked!! I can't believe what happened! After a year of having black hair, with a 20-minute application, they turned chestnut red!! The truth is, of course, that I hadn't dyed them for many months.. but the black color wouldn't fade at all. Two hair salons told me that they can only lighten it with decolorization and that there is a high chance of damaging it because I have thin hair.. the tip I will give you is.. after you finish the process.. when your hair is wet.. apply a 10-volume peroxide for a minute with a timer and then wash it again.. (that's what they told me, where I bought it, that it helps prevent them from darkening again).. and dye.. they told me, after 2 days on completely dry hair. It is an amazing product... and personally, the smell didn't bother me at all.
No more decapitated girls.... This product is amazing.... I'm amazed.... In black-blue dye, (on light chestnut hair), in three days with one application my color came back ...!!!! (to the color I had three days before). If you don't see it with your own eyes, it's hard to believe!!! Bravo!!!!????? Be careful with the uniform application...
I will give it one star!
I had dyed my hair black and the color had faded about two fingers' length. I applied the product to my entire hair and only the roots lightened to a reddish brown color! I applied it 2-3 times because it promises to remove the color completely without damage, but the result was that my hair smelled awful for days even after washing it!
The black color never went away and it ruined my hair!
This specific product only works on lighter shades, so if you want to lighten your hair by one tone, forget about it if you have black hair... unfortunately, you will either have to leave it as it is and go for a haircut or professional color removal occasionally
Well..... I used it on black hair and on the first day it turned brown. After two days, I dyed it red and it goes back to black except for the roots, which smell like red. I really think this product is not worth the money I spent.. besides, it made my hair rough. I really want to swear, but I'm holding back
It does not dry the hair, it does what it promises from the first time, only the smell is the issue, but since you avoid bleaching, it is worth it. I had dark black hair and they turned almost brownish-red, close to my natural color
My hair has been blue black for almost 2 years now, when I use the product I will come back...
part 1 I used it on black hair that hasn't been dyed for a long time and it made it brown, somewhere lighter somewhere darker, but the smell is strong even after 3 shampoos on the same day. I will have part 2 where I will use it again because I have half left, I will come back for the final result...
I do not consider this product to bring my hair back to the phase it was in before bleaching, because I had only dyed my hair brown three times after being blonde, and it has not been a long time since then, yet it turned red. I believe that in general it can bring you to a reddish brown, so if someone wants to make a change to red, it is ideal! However, if you want to become blonde again, you will have a hard time correcting the red. It smells very bad even after days.
