Anti Copper & Yellowness Shampoo Kerastase Blond Absolu Bain Ultra Violet

This is an excellent shampoo that gives a beautiful ashy shade. It lasts even after washing with regular shampoo. It is recommended to leave it on for at least twenty minutes as it doesn't have the same effect if left on for less time. There is no unwanted bluish tint. The price is high, but it is definitely worth it.

I have my hair dyed using the AirTouch technique, and after bleaching, my hair became dry. This shampoo cleanses it wonderfully and gives it a nice tone (I use it once a week, otherwise the results are not visible). However, it definitely doesn't nourish or restore it, so after two washes, it becomes even drier and tangled. It is necessary to apply a mask or conditioner after shampooing, otherwise it cannot be combed. Just a conditioner won't work if you want your hair to be well-groomed. I also use the Perfector No.3 hair product, which does a great job with its task, so I can use this shampoo; otherwise, it would be difficult to use this shampoo.

Works very well, highly recommend it!!!

The shampoo is amazing, but without conditioner or a hair mask, it can severely dry out your hair. You can try another product from the same line, in theory, as long as it effectively moisturizes and lasts longer.

In terms of color preservation, it works excellently. However, without the use of a matching nourishing mask, it greatly dried out both the hair and scalp. That's why I can only give it 4 stars for now.

First, your hair transforms into a dreadful sight, appearing tangled until you wash it. I always use shampoo twice in one go. Then, I blow dry it with cold air, slowly combing through the hair, and it becomes obedient and smooth. When fully dried, it looks well-groomed, feels light, delicate, and silky. The hair becomes perfect.

This product is excellent. I use it in combination with foundation and a mask. It does not leave any blue or purple shades. It is recommended in salons for a reason, as it greatly improves the condition and color of the hair.

After using this shampoo, I decided to try out the entire range of products, and I must say, I am very pleased with all of them. They truly deliver results and help to prolong the color.

My sister and I both went blonde at the same time and switched to this shampoo back in the summer. Since then, we have never been disappointed with our choice of this shampoo.

One of the best shampoos for blondes! As they say, "top for its price" :)

My favorite shampoo, although it initially dried out my hair. It seems to be designed to be used with other products from the same line, as the problem disappeared after adding conditioner to it.

I have tried both shampoos from the Blond Absolute series and this one appealed to me more. The cool blonde is guaranteed.

The "bath" attachment after shampoo is quite entertaining)))
Overall, this shampoo is excellent, although it did dry out my hair a little at first. However, when used together with the conditioner and hair mask, the result is absolutely fabulous.

I really liked the shampoo. It helps to maintain the color of my hair for a longer time without any yellowing. Moreover, it makes my hair smooth and silky. The scent is subjective, similar to fondant, but it is not overpowering and doesn't become annoying over time.

It is extremely drying, incredibly drying! When it gets on your hands, it stains them purple and even leaves the skin excessively dry! It does not give a beautiful color. I do not recommend it. It is not worth a penny!

I have balayage on my natural hair. This shampoo leaves a yellowish tint on the natural part of my hair and it dries out the lightened part very much. Moreover, using a hair mask afterwards intensifies this effect even more. I do not recommend it.

It doesn't foam at all, so it's not very convenient to use and the consumption is high.

I received a sample to try out and I'm very satisfied. The sample is enough for one wash, there's no need to divide it for two. However, even with that being said, the shampoo removed the yellowing after just one wash. It doesn't lather much, so there's a desire to pour half the bottle on myself, but it's not necessary because it does its job without lather ;) Then I tried the conditioner, which has a very nice scent, and thermal protection before drying. I fell in love with this line because my hair became silky and obedient, which is not easy to achieve with bleached hair.

This is an excellent product that I use in combination with a conditioner-foundation. It does a great job of toning without any purple or bluish tint. I apply it once a week for a few minutes. My hair is happy and well taken care of, and the color looks fresh, as if I just came from the salon. I highly recommend it.

This shampoo is extremely drying, especially for already dry blonde hair! It's just an ordinary toning shampoo like any other affordable option.

I like it! However, in the reviews, they say that it only takes 3-5 minutes for noticeable effects. The first few times, I didn't notice any changes in my hair (which are dry, medium brightness balayage blond). It wasn't until the third time that I left it on my hair for about 17 minutes that I noticed a difference. I use it once every one and a half to two weeks, keeping it on for about 15 minutes. Using a hair mask or conditioner is necessary, depending on the condition of your hair. I alternate between the two.

I bought a shampoo that wasn't from Makeup. It corrects the tone really well without any bluish tint, but it leaves my hair terribly dry. It also makes my scalp itchy (I have sensitive skin). It is definitely necessary to use a conditioner after using it.

Awesome shampoo!
I love how it makes my hair dry faster, I have no idea what kind of magic this is!

The shampoo is truly amazing! I wash my hair daily, and I can't say that it really dries out my hair. Compared to other brands (and I have tried many!), this shampoo doesn't dry it out at all! Plus, you still need to apply conditioner, balm, or leave-in products after shampooing anyway... The shade is stunning after use. I use it every other day. It's very economical!

The shampoo gives a beautiful shade, but it's not violet. The only downside is that it's definitely not suitable for everyday use. Although the salon stylist assured me that it can be used daily. I used it for several days in a row and it slightly dried out my hair. Now I'm trying to restore it. However, it's worth using it for the shade. But be careful, as it does dry out the hair. Use it 1-2 times a week, no more frequently.

The shampoo is excellent. It works wonders on yellowing. I don't use it every time I wash my hair because it gives a gray color. My hair is thin, but I can style it without any issues! Thank you for the fast delivery and the quality of the product!

I really like this shampoo, I just ordered my third bottle. I have red hair and I've been dying it blonde for many years. My natural pigment is not warm, it's hot. But this shampoo handles it perfectly until the next coloring.

To achieve the desired result, it's not necessary to use both the shampoo and the mask. Just the shampoo alone is enough. It's more convenient for me to use the shampoo because I only need to leave it on my hair for about 3 minutes, while the mask needs to be left on for about 10 minutes, which is not always convenient (practically never) during morning preparations.

After using this product, along with the conditioner from the same series, my hair smells unbelievably amazing. It feels incredibly smooth and soft too! I no longer need any hair masks. It even restored a cool undertone.

I purchased this together with the mask. It effectively removes yellowness and moisturizes well.
