Repair Leave-In Serum for Very Damaged Hair Kerastase Resistance Therapist Renewal Leave-in Serum

This serum is amazing! After using it, my hair feels soft and shiny.

I have bought this product 10 times already. It makes combing easier and adds shine to the hair. I also use it on dry hair ends when needed. It's a good product with a light scent.

I have been using this product for several years now, especially during periods when my hair is damaged from chemical perms. After using it, my hair feels soft and shiny. I highly recommend it!

The serum is definitely worth attention. It leaves the hair smooth and easy to comb. It doesn't weigh down the hair or leave a greasy residue, even when talking about severely damaged hair. As for the cons, it is quickly consumed (one press is not enough) and the dispenser poorly dispenses both products simultaneously.

The serum is probably not bad, but I also have issues with the fact that the creamy liquid does not flow out. The responses from other users with a similar problem amused me, "develop a pump" - but how? Just squeeze half of the serum onto my palm?))) I only apply oil because the cream simply does not flow. I will not buy such a troublesome product again.

I couldn't resist and ordered during the Black Friday sales. I have used it several times. The plus side is that it works on hair just as it is stated!! I have porous and dry hair with damaged ends. I applied it to damp hair - amazing!!! But for those who lack volume, it will become even less:)
On the downside - I have to press five times to get the second composition out... it's very wasteful!! And there is very little of the product itself.

This serum is excellent, it makes your hair silky smooth and reduces split ends.

I'm not a fan of Kerastase, their shampoos and masks don't really work for me, but this product actually does. I started using it after getting a haircut and it lasted me a long time. After three months, I hardly had any split ends, which is usually a problem for me after just one month. So, it definitely has an effect. I still had the desire to trim the ends because they were a bit dry, but for preventing split ends, it's the best thing I've tried so far.

This is a fantastic product, especially when used in combination with the shampoo, mask, and serum. The results are simply amazing. Out of all the products I have tried in my life, this one has the most restorative effect. When used correctly, it lasts a long time. The key is to lather it in your palms, then a little goes a long way. The mask also has an incredible effect, even with minimal usage.

I ordered the haircare set - shampoo, conditioner, and protection on May 16th. I have been using them for 2.5 months. Only the conditioner has run out. My hair is thin, brittle, dry, curly, and porous. It is not thick. My hair has never been in better condition. Firstly, I have started washing my hair less frequently, and it stays fresh for a longer time. The hair strands have become nourished and less porous, resulting in less frizz. They don't split as much as before. The root volume is maintained. I am very satisfied and will continue to use it.

I purchased a sample because I really wanted to try it as I already have the shampoo from this series and I am thrilled with it, it's simply amazing. The shampoo was given as a gift.

I intentionally applied the serum after using another shampoo, without using a mask or conditioner, in order to fully experience the product.

There was practically no effect. My hair is blonde and has complex coloring.

I don't understand the enthusiasm! I have probably tried all the popular serums. I liked the pink Elixir from Kerastase the most.

This one has a pleasant scent and even after a day it doesn't make my hair greasy, it slightly smoothens it.

This is a great serum that I applied all over my blonde hair before styling. I also used the Kerastase mask from the same series. The serum is excellent, but the quantity is a bit small for me. For now, I will go back to using the Keune Vital Nutrition thermal cream that I used before.

I purchased shampoo, conditioner, and serum from this store - I didn't like the packaging, it was very messy and seemed like a counterfeit. However, I really liked how my hair looked after using the products. The serum lasted for 5 applications, and now I only have the oil left, the white substance ran out. I will be ordering again because I still have the shampoo and conditioner, but not from this store. Although, I am satisfied with the service from Makeupa.

I was contemplating for a long time whether to buy it or not, as it has a small volume and is quite expensive. However, in the end, I decided to go for it and I made the right choice! It is so amazing that I never thought I would be so obsessed with my hair. The ends are smooth, silky, they don't tangle, and there is significantly less split ends. I have already used three of them and I realize that I won't be able to live without it anymore!

After several uses, one of the two phases of the serum stopped appearing after pressing (the one that is white in color), meaning the bottle turned out to be defective. I bought it a long time ago and it's still there, it's a shame to throw it away, but using only one oil is also not an option.

I really liked this serum. It is suitable for my long, fine hair and doesn't weigh it down (unlike some silicone or oily serums). I only apply it to damp hair and it gives me shine, smoothness, easy combing, a pleasant scent, and an overall great look... I am very satisfied. The only downsides are the price and the size.

I really like it! The hair looks very beautiful, and it works wonders even when they are dry.

Of course, the price is a bit high. I probably won't buy it again, I'll look for more budget-friendly alternatives.

I enjoyed the scent of this product. It immediately moisturized the ends of my hair upon application, but the effect wore off after a few hours. CHI oils provided better moisture for my hair.

Powerful serum!! However, it is not suitable for my fine hair when applied to wet hair (even with just one pump - it clumps, weighs it down, and gives a feeling that there is something on the hair, it can be felt by hand). I apply it to dry hair overnight before morning washing. I agree about the pump - it poorly dispenses the creamy part, it comes out every 5 times.

Now the ends look cool thanks to this serum. It's awesome, I can't remember any other product with a similar effect. I always considered frayed ends as normal and thought it was just time to get a haircut, but with this serum, that's no longer the case. Finally, my hair will be able to grow to a good length!

The hair is dyed blonde, but this product did not work for me. The price seems to be more for the brand rather than the results. Personally, I fell for the advertising and it was a mistake. By the way, there is also very little of it - it only lasted me a little over 2 months of occasional use.

My love! I can't imagine my hair without this serum now. I'm on my second jar, and my hair feels like silk after using it. I constantly want to touch them. This product is really amazing, so go ahead and buy it. I highly recommend it!

I have seriously damaged my hair from dyeing it and was searching for a product that could revive them even just a little bit. Well, this serum did something unbelievable! I have tried many different serums and oils, but this one is now my favorite. My hair feels thicker, shines, and looks much healthier. I definitely recommend it.

"The best remedy for damaged hair! The dry ends have become soft and silky."

Very good serum. I will definitely buy it again.

I have been using this serum for exactly a month now. I apply it to wet hair after washing, before drying, and my hair dries faster with noticeable effects. Additionally, I apply the serum to the ends of my hair every day, followed by the Kerastase night serum, and the results are excellent. However, when I apply only this serum to dry hair, the ends somehow become tangled afterwards. Overall, I am satisfied with the product. Although I'm not sure how long it will last, one pump is enough for one use. And the scent is amazing! I also use Kerastase restoration shampoo and I like it.

This is a really great product. I can't live without it now. My hair always looks well-groomed and it genuinely doesn't split. I bought it on sale and have been using it almost every day. One bottle lasted me for about 2.5-3 months.

The serum is simply amazing and works perfectly! And the scent is very pleasant) The makeup was delivered very quickly!
Thank you)

The best hair product, worth its price. It has minimal consumption, just one pump is enough for long, bleached hair. After blow-drying, the hair feels soft, like after expensive salon treatments.

Mmm, it's so wonderful that I recommend it to everyone! The results are visible after the first uses. Beautifully cared for hair, nice and smooth instead of split ends. It dries my hair twice as fast, and the scent is out of this world!
