I don't understand what is wrong with this product while I am a fan of Kerastase. It makes my hair awful, hard, dehydrated, and frizzy. I wonder why I spent 40 euros. On the contrary, another product I had bought, a night serum but not from the blonde series, had a wonderful result. I do not recommend it nor will I buy it again.

I can say that the result in terms of softness to the touch is mediocre to indifferent, plus the hair looks unwashed and dehydrated afterwards! And if you say to put more, it will get even worse! I personally liked its scent.. for this price and the name, it definitely isn't worth it

I put it on at night on the ends of my hair with damaged highlights, and in the morning it is stiff as if I have applied gel. I don't know why this happens, but I am not satisfied at all, not at all

I think for the price and the amount in ml, it is better to buy the mask from the same series that has a lot more product

I have used countless hair products and with this one, you can already see a difference from the first time. 2-3 pumps and application on the ends of the hair before sleep, braiding to prevent breakage during sleep, and in the morning, the hair is very soft, shiny, and smells amazing. Also, you feel that the hair is extremely lightweight. I highly recommend it to people who care about their hair and have colored hair/highlights. Simply wonderful!

Amazing product just like all the others from this company, I apply it to my hair after blow-drying and before going to sleep, and I wake up with salon-worthy hair. Ever since I started using the entire range, my hair has changed and it shows.

Simply amazing!
It helps a lot with styling!
Most of the time, I just dry my hair, apply the product, braid my hair, and go to sleep. The next morning, the result is fantastic!

I use it every night, applying a small amount as my hair is medium length. In the morning, my hair is hydrated and the difference is noticeable.

It doesn't make my hair oily, it moisturizes it, and it's like it hasn't been bleached. After using it, my hair feels refreshed and is easily combed immediately.

I use it in combination with the purple line of the same brand.

When you apply it, you feel your hair fine and moisturized. The dry ends of the hair, which are dry due to the dyeing, are greatly improved. However, I did not see any improvement when I did not use it, and its scent is very heavy, like smoke from a cigar. It is impossible for me to use it at night before sleep. I did not see any long-term results.

First day of application and it seems amazing, wonderful scent, makes hair soft and shiny. If there is any negative aspect, I will mention it here later! Anyway, first impressions are very good, it's fantastic. I came back after a long time, I think months, and in the end, I don't like it, it's like this serum does nothing

From the moment you apply it, it repairs hair that has undergone bleaching and makes it elastic and healthy. It has a slightly strong scent (something like a masculine fragrance combined with a strong botanical smell, definitely not pleasant for everyone), but it disappears and doesn't stay in the hair at all. I feel like it is absorbed into the hair shaft and it's not just an external layer. I frequently bleach my hair and have tried many products (Moroccanoil, Chi, Redken Argan, Biosilk, etc.), but this serum is like no other

Very good product! Indeed gives shine and moisturizes. The only negative thing is that, for people who do not wash their hair often (like me, especially in winter I wash them once a week), I think that by the 3rd day it weighs them down. Other than that, it is a super product.

I apply it before I go to sleep and wake up with soft and hydrated hair. The longer I use it, the better my hair feels.
