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

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

I have purchased 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 is 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 becomes soft and shiny. I highly recommend it!

The serum is definitely worth attention. Hair becomes smooth and easy to comb after using it. It doesn't weigh down the hair or leave a greasy mark, especially when it comes to severely damaged hair. The only downsides are that it is quickly consumed (one press is not enough) and the dispenser poorly releases both products simultaneously.

The serum is probably not bad, but I also have problems with the fact that the creamy liquid does not flow out. The responses from other users with a similar issue amused me, "develop a pump" - but how? Just squeeze out half of the serum on the palm?))) I only use oil because the cream simply doesn't flow. I won't be getting such a troublesome product anymore.

I couldn't resist and ordered during Black Friday sales. I have used it several times. The pros are that it works on hair as indicated!! My hair is porous and dry, with damaged ends. I applied it to damp hair - amazing!!! But for those who lack volume, it will become even less:)

The cons are that I have to press five times for the second composition to come out... it's very wasteful!! And there is very little of the product itself.

This serum is really great. 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 for a long time. After three months, I hardly had any split ends, whereas usually it would happen within a month. So, there is definitely an effect. I still had the desire to trim the ends because they were a bit dry, but in terms of preventing split ends, this is the best thing I've tried so far.

This product is excellent 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 restoring effect. When applied correctly, it lasts a long time. The key is to lather it on your palms, then a little goes a long way. The mask also provides an incredible effect with minimal usage.

I ordered the hair care set - shampoo, conditioner, and protection on May 16th. I have been using it 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 wash my hair less frequently now, and it stays fresh for longer. The strands have become nourished and less porous, which means they are less frizzy. They don't split as much as before. The roots have more volume. 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 purposely 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 a complicated coloring process. I don't understand the enthusiasm! I have probably tried all the popular serums. The pink Elixir from Kerastase is my favorite. It has a pleasant scent and even after a day, it doesn't make my hair greasy, it slightly smooths it.

This serum is great! I applied it all over my blonde hair before styling, and I also used the Kerastase mask from the same series. The serum is amazing, but the volume 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 bought shampoo, conditioner, and serum from this store - I didn't like the packaging, it was very messy and looked like a fake. But I really liked how my hair felt after using the products. The serum lasted for 5 uses, and now I only have the oil left, the white substance ran out. I will order more because I still have shampoo and conditioner left, but not from this store. Although I am satisfied with Makeupa's service.

I debated for a long time whether to buy it or not, as the size is small and the price is high. But 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 thrilled with my hair. The ends are smooth, silky, they don't tangle, and they split much less. 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 upon pressing (the white one), meaning that the bottle turned out to be defective. I bought it a while ago, and it's still there, so it's a pity to throw it away, but using only one oil is also not an option.

I really liked the 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 nice scent, and overall appearance... I am very satisfied. The downsides are the price and the volume.

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

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

I really liked the scent of this product. It instantly moisturized the ends of my hair upon application, but the effect wore off after a few hours. The CHI oils provided better moisturization for my hair.

Powerful serum!! However, it is not suitable for my fine hair when applied on damp hair (even with just one pump - it makes them sticky, heavy, and leaves a noticeable residue that can be felt with the hands). I prefer to apply it on dry hair at night before washing it in the morning. I agree about the pump - it doesn't dispense the creamy part well, only coming out every 5 pumps.

Now the tips look cool thanks to this serum. It's amazing, I can't recall any other product with a similar effect. I always considered frayed ends as normal, thinking it was just time for a haircut, but with this serum, that's no longer the case. Finally, my hair will be able to grow long and nice!

I tried this product for my dyed blonde hair, but it didn't work for me. The price seems to be more for the brand rather than the results. I fell for the advertising, and I regret it. By the way, there was also very little product, it only lasted me a little over 2 months of intermittent use.

My love! I can't imagine my hair without this serum now. I'm on my second jar and my hair feels as smooth as silk after using it. I constantly feel the urge to touch them. This product is really amazing, so I highly recommend buying it!

I have severely damaged my hair through coloring, and I was looking for a product that would help revive them even just a little bit. Well, this serum did wonders! I have tried many different serums and oils, but this one is now my favorite. It has made my hair thicker, shinier, and much healthier-looking. I highly recommend it.

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

This serum is really good. 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 blow-drying, and my hair dries faster with noticeable results. Additionally, I apply the serum to the ends of my hair every day, followed by the Kérastase night serum, and the effect is excellent. However, if I apply only this serum to dry hair, the ends tend to get tangled afterwards. 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 superb! I also use the Kérastase restoration shampoo, and I like it.

This is an excellent product. I can't do without it now, as it keeps my hair well-groomed and prevents split ends. I bought it with a discount and have been using it almost every day. One bottle lasted me around 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 every penny. It has a 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 is so wonderful that I recommend it to everyone! The results are visible after the first uses. The hair looks well-groomed, with nice "tied" ends instead of split ends. It dries my hair twice as fast, and the scent is out of this world!
