Difficult shampoo to use but it does what it promises. It doesn't foam, it feels heavy and it doesn't soften the hair. Despite all this, however, it is excellent for fine fragile hair as it gives them body and resilience. I will definitely buy it again!!!

I bought it because of the reviews I read. It doesn't soften my hair or make any difference to my hair, I didn't see any improvement at all. Unacceptable for its price, I won't buy it again

Personally, it does not hydrate my hair. On the contrary, I feel them very dry and the mask from the same series confuses them, while on the other hand it makes them smooth and easy to comb! Maybe it's not suitable for my hair ....

The best shampoo ever!!! The only shampoo that leaves the hair moisturized and full even without the mask! In combination with other products from the same line, it works wonders on the hair! I constantly buy it

It leaves the hair very soft, however, mine needs conditioner afterwards. What I did to make it work better was to use a smaller amount than a walnut and dissolve it in my hands, then spread it on my hair. I leave it on for 1-2 minutes and rinse. It doesn't require a lot of quantity.

My hair is in terrible condition and with their first use, they gave it life. Perfect. Okay, it's very expensive and has few ml, but I understand why. However, I will find it difficult to buy it again due to the price. I bought it once to give it a boost

It is a good shampoo, I have dyed hair with highlights. It helps a lot to moisturize my damaged hair, but it definitely needs a mask afterwards. One negative aspect is the packaging without a pump, only a tube, so a lot of product is wasted. Such a good company should fix this.

Words are not enough for this shampoo: 2 hazelnut quantity and it foams a lot even in my very long hair. It leaves them incredibly soft and detangles them as if you have applied a mask. It smells wonderfully discreet and it lasts. It is gentle on the scalp, it does not irritate. It also moisturizes my ends, which have undergone bleaching and dyeing 4 times and are generally thin hairs that break easily. I truly feel that it is therapeutic!

From the first use, I noticed a significant difference in my hair, which is thin with split ends and frizz. It has a perfect scent that lasts for hours.

It has been 2 months since the first application. I wash my hair 3 times a week and even though I had bought two packages, one in September and the second one I started in November. It requires a minimal amount in the palm with a little water and then you apply it to your already wet hair. Therefore, with a minimal amount and two hands at a time, it can last for 2 months. My hair, in combination with the mask of the same series, has completely transformed even with fewer applications. So now I am 100% convinced that I am not wasting a single minute on the money I spent on this purchase because otherwise I would have spent it at the hair salon. I will definitely try other Kerastase products. It is worth it and more.

It is the best thing I have ever used on my hair, which I have really damaged. Of course, because it is expensive, I first wash my hair with a good commercial shampoo and then use this. I only need a small amount. I buy it again and again because it is the only professional shampoo that has satisfied me.

I use it in combination with the mask from the same series and it is the best for damaged hair!

It is simply fantastic. It leaves the hair smooth without weighing it down. After using it, there is no need for conditioner cream.

It is quite expensive. Of course, it is worth its money. But it is not cost-effective. Even though they say a small amount is enough, I disagree. I have a lot of hair and a couple of drops are not enough. Whenever I use it, I have to use a lot. It is suitable for people with thin or short hair
