Don't buy it!!! Stay really away from this product.
1. The smell can actually make you sick
2. It does nothing
3. It's only water, not anything else

I have black to very dark chestnut hair. I had bleached my hair and my hairdresser applied toner to my hair twice to remove the yellow tint from the bleach and to achieve a light platinum hair towards silver. After 2 days, I noticed that my hair started to turn yellow again. As a last resort, I decided to try the product - since I am on vacation, away from the salon - and I have to say that I got the platinum toner.
It doesn't smell nice but it's bearable. I left it on for 15 minutes longer and when I removed it, I felt that it didn't take away all the yellow tint, so I used a silver shampoo from Elvive and my hair became much brighter and most of the yellow tint was gone, but not all of it.
I think for something urgent and economical it's okay, but it's better to go to the salon with the techniques and recommendations of the experts for products and applications.

The smell is like a cheap paint. But if the color has been well opened from highlights, for example, and you want a toner to break the yellow, then it does a satisfactory job in erasing unwanted tones.

It is one of the most commendable products available in toners that you can find even in the supermarket... The color will come out according to the base of the hair opening, so will the corresponding color... The smell is awful, but that's how a cheap dye smells... at least the result is worth it if you don't have money for a hair salon or time. It is not a conditioner or shampoo to have a nice smell. Instead of a hair dye, you get this and do your job!

Terrible product, a waste of money. It smells incredibly bad and the odor doesn't go away, plus it didn't have any results

Very satisfied with the result!!! I have bleached my hair and wanted to remove all the yellow color of the blonde, even though it required more than 10 minutes as stated on the packaging (I left it for 35 minutes). The color came out very nice, beige, and it didn't smell bad as I expected from other comments. For a perfect result, I used a mask and then conditioner. Also very satisfied with the quantity of the product, as I have thick hair.

If you have even a little bit of orange hair, don't even think about putting it on your head because it will turn into intense orange-brown. It might work on yellow hair. But for a little bit of orangey hair, DO NOT TRY IT!!!!

Unacceptable product! Its smell makes you faint! I have no opinion on the color result because I couldn't stand the smell and washed it off immediately.

I have blonde highlights... I hadn't done silver for months... all the yellowness disappeared, the color came out and my hair didn't get dehydrated at all compared to other silver shampoos I used... I will definitely buy it again, its price is amazing for its quantity and result. I will definitely buy it again!

The review is about the blonde sandre, don't expect tremendous changes in very yellow-golden hair, since it is called a "toner" you expect a stronger result. Additionally, it smells really awful and this smell remains in the hair even after rinsing, overall a waste of money.

To me, it didn't do almost anything and then it left a strong smell on my hair. But it may just be my hair's fault!

Truly miraculous product. Balanced the existing highlights I had, which were almost like a tricolor cat, into a beautiful shiny sand color! Lots of shine in the hair, very uniform color. It doesn't provide much hydration, but it doesn't claim to do so from the beginning. I recommend it to everyone, it's like going to a hair salon and getting highlights!

It did indeed remove the brassiness from the highlights. I applied it twice to my hair because the first time there was a slight difference. The second time, I left it on for a longer time and it had an effect.

This particular shade performs better on light, uniformly bleached hair, otherwise it does not have the expected result. In my case, it removed any remaining yellow tones and gave my hair a grayish, very cool shade. I left it on for longer than recommended, about twice the time. When drying, my hair was quite soft, although I added conditioner at the end for extra hydration. The result lasts depending on how often someone washes their hair. It definitely needs to be reapplied at least 2-3 times a month to maintain a more intense color!

I cut my hair very short so that it could withstand the process of bleaching once again. Some parts turned orange and I made the mistake of buying it because I found it at a 50% discount. The result? It darkened my hair as if I had never bleached it before. It gave them an orange shade and especially in the areas that were already orange, it made them a strong brown-orange color! It's tragic, they should compensate for the mental anguish. DISGUSTING

Satisfactorily eliminated the yellowness and opened up the hair, giving it a cool tone. It also left the hair very soft and did not dry it out at all.
