I bought it in order to get rid of the reddish-orange tones in my hair. I dye my hair dark brown - which is also my natural color - and after 5-6 washes, this lightening towards the reddish-orange mainly appears from the middle of the hair to the ends. This particular shampoo did nothing except stain my hands (and under my nails), as I forgot to wear gloves during the first application as recommended. The smell is not unpleasant, the hair is definitely drier and dehydrated, so I used a mask after washing, and it is certainly ineffective at least in my case. I will also try the green color in case I made a mistake in choosing the blue shampoo

Terrible... Stay away. It completely ruined the color of my hair and instead of removing the orange, it made it yellow. Waste of money... I will have to do a color correction to fix it

Conditioner after use because it makes my hair very hard for me.

I used it when I had my hair dyed blue and it did a pretty good job.

The smell is nice although very artificial.

The plus side is that it effectively eliminates yellowing. But if you don't have strong/resilient hair, it damages them and they can't be saved even with a mask. I left it on for 2-3 minutes and my hair became a mess (I have thin hair). And afterwards, my hair smelled awful, like medicine. In the end, I threw it away...

Like all related shampoos, it leaves the hair dry but it is quite good. In combination with its conditioner, there is no issue with combing! You have to leave it on for at least 5 minutes or more for it to work well, but it needs to be rinsed off immediately from your hands because it stains very quickly (its conditioner does not stain as much). I have brown hair that has been lightened by the sea and sun and had a reddish tint. It evens out the color quite well with a cool blonde shine. I will buy it again!

There is no result in either medium blonde or light brown hair with orange undertones. I made many attempts, even using it on dry hair as a mask. Bad purchase.

I was not satisfied with this shampoo... I didn't notice any orange removal at all, maybe it even made it more intense, I have the impression. I stopped using it... No-yellow is by far better.

Finally, I found what I've been looking for for 18 years now, to remove the "yellowing" from my blonde hair. Well, it turns out it was orange tones and not yellow tones. It leaves me with the cool blonde that I want, clean! I recommend it!

It corrects the color of the hair dye. The yellow color of the hair dye becomes gray (as desired by the wife). The hairdresser recommended it to her. The desired color result was achieved.

Nice product. It has a pleasant scent for its category, it does what it promises, it eliminates orange tones. After using it on wet hair, it leaves the hair relatively soft compared to other blue or purple shampoos. It definitely requires the use of gloves during application to avoid staining the hands.
Overall, the best in its category.
