Hair Serum Kerastase Nutritive 8H Magic Night Serum

I have been using it for a short time, so I cannot say anything about its healing properties for hair yet. However, I really hope it helps because I have wanted to buy it for a long time. I will write about whether it helped after using it for a longer time. I have dyed blonde hair. Girls, please advise if you use it, do you apply it every evening as instructed? For now, I apply it after washing my hair because I'm afraid of overloading it if I apply it every evening, in case it has the opposite effect and causes disappointment from excessive use.

The serum is excellent, leaving my hair moisturized and shiny. However, I was even more impressed with the Blond Absolu Serum Cicanuit in terms of its effects.

Definitely one of my favorite products. I have very dry and brittle hair, but after using this, they become lively, nourished, and shiny!

Why did the product come without the plastic film?! How am I supposed to know now if it's the original liquid inside?!!! And don't tell me it's the manufacturer's fault! I've ordered it not for the first time and it always came with protection!

The serum works well. I have bought it multiple times. It has a pleasant smell. In the morning, my hair looks well-groomed, is easy to comb through, and appears healthier. The most important part is that it seals the ends. However, as long as you use it, everything is fine. As soon as you stop using it, everything starts over. In other words, it has more of a cosmetic effect rather than a healing one, and it does not have a cumulative effect. Don't expect a "wow" factor, but the serum is not bad. It is not economical to use, so it won't last long. If you want to pamper yourself and indulge, go ahead and order it.

The product worked well for both me and my husband. It is effective for very dry hair, moisturizes it well, and leaves it soft in the morning.

Does nothing special to the hair. It only has a pleasant smell. I didn't like the product. I won't buy it again.

I'm glad that I got a sample of this mask. I really wanted it, but after 5 days of testing, I conclude that the only positives are the scent and the softness of my hair for the first couple of hours after application. Within a few hours, my hair becomes extremely dry and frizzy again.

After 3 months of use, it seems like the product does nothing. There were no changes at all overnight, I was hoping for a cumulative effect, but in vain. It only leaves a pleasant scent, nothing more. Rating: 2/10.

I really liked this product, but the results become noticeable after several uses.

I really liked the lightness of this product, as it doesn't weigh down my hair. Additionally, the fragrance is fantastic and refreshing.

This pleasant serum takes hair care routine to a new level. However, it is quite lightweight. Water is the main ingredient, followed by silicone and conditioning agent. Therefore, it is sufficient for taking care of the length of the hair, but the ends require additional application of a richer oil.

In terms of texture, it is a cream that does not weigh the hair down. It absorbs completely overnight, softening and conditioning the hair.

If the goal is to grow long hair, additional protection for the ends in the form of more concentrated silicones is necessary to simply prevent mechanical damage and breakage, preserving centimeters until the next haircut.

I have used this product as directed more than five times, but I didn't notice any significant effects.

The product is truly effective! All the claimed characteristics correspond to reality. After the first use, the results are already visible - I applied it before bed and in the morning my hair is incredibly soft, smooth, and shiny. The scent is simply magical, floral, and very long-lasting, yet it is not overpowering. I am very satisfied with the purchase.

This product is really cool with an incredible scent.

I really liked it. It worked well for my thin and long hair, it doesn't weigh it down and provides silkiness and moisture. My hair shines beautifully. I usually used it on wet hair before blow-drying, like a regular serum, not as an overnight treatment - and it worked well that way too.

I have been using the entire Kerastase line and I am thrilled with it. It has saved my dry hair. However, this serum is the most useless one. It does nothing for my hair, there is no effect. I will not buy this serum again, it's not worth my money.

I don't know the exact composition, but if there are silicones, it's logical that it improves the appearance. I have naturally light brown hair that is greasy at the roots and dry from the middle to the ends. I wash it every morning, blow dry it, and apply this product before drying. My hair feels soft, smooth, and straight, and it helps to tame any flyaways. However, I only notice a purely visual effect and don't see any changes in the condition of my hair.

I apply it at night on dry hair. My hair is dry at the ends, so I apply it to the bottom third of my hair. It makes my hair softer and adds shine. However, I don't see any magical effects. Personally, I think a liquid silk product would suit me better, as this serum doesn't really do anything special in terms of hair care. But to each their own!

I have natural, uncolored, brown hair that is greasy at the roots and dry with split ends. I used this serum five times in combination with Kerastase Specifique Bain Divalent Balancing Shampoo and Kerastase Resistance Masque Force Architecte mask.
Unfortunately, I did not notice the "wow" effect that everyone talks about. Yes, the smell is quite intense and it lingers in the hair for a while, so you have to choose between smelling like the serum or wearing perfume.
I tried using the serum in different ways - applying it to damp hair before bed, on damp hair and then blow-drying, on dry hair... My hair became slightly softer, like it usually does after using a drugstore product. However, I did not notice any salon-like effect, not after the first use, not even after the fifth use... :(
Also, I found that it is not as economical compared to Kerastase L'incroyable.

This product is very pleasant and nourishes weakened hair well during winter, giving a well-groomed appearance. And the fragrance is simply incredible, it's a pleasure to use it!

This serum gradually revealed its wonders to me. At first, I was greeted with a delightful scent and a creamy texture. Over time, with regular use, it worked miracles on my hair. They became nourished and moisturized, soft and beautifully styled. My dry curls have never felt so alive. It's pure love.

This is an excellent product for damaged light hair! It has a pleasant and rich aroma, as well as a light consistency. The serum is very convenient to use. I apply it on clean, dry hair at night before going to bed. During this time, while I sleep, the serum actively moisturizes and restores my hair. In the morning, my curls look neat, the hair doesn't become greasy, and I can start my daily styling routine. By the way, the scent remains on the hair even on the second day after use! I really liked it!

This product is amazing! My hair tips have become as vibrant as ever.

This is absolutely fantastic!
To be honest, I wasn't expecting such incredible results - my hair becomes incredibly smooth by morning.

I apply the serum in the evening on freshly washed and slightly dried hair. The consistency is very lightweight and it spreads easily. The serum has a pleasant scent and does not weigh down the hair at all. In the morning, my hair is easy to comb and looks well-groomed.

This is the best hair product... ))) It has a pleasant scent and almost immediately after application, my hair became soft and manageable.

A serum with an incredible aroma! I apply a small amount, and it is very economical. In the morning, my hair is soft and manageable, and the best part is that this serum helps protect my hair from heat styling and strengthens it perfectly! There is no greasiness in the morning, only a light scent remains. I definitely recommend it!

A great tool for those who don't like spending hours wearing masks on their heads! It really works! Hair feels like after salon treatments!

The serum is effective. It has a very nice effect and a pleasant scent. After using it, the hair looks significantly better.

This is a real find! The hair is incredible! Shiny! Vibrant! The care is like being in a salon at home! I have long and thick hair, but a little bit of the product is needed.

The hair is soft, manageable, and easy to comb. I highly recommend giving it a try.

My curls are thrilled with the softness and shine after using this serum. It works overnight, penetrating deep into the hair structure and repairing damage. The scent is fantastic. I use it with great pleasure and highly recommend this product to everyone.

I have dry and brittle hair. I have been using this product for many years. I apply it to my hair after every wash. It is the best hair treatment! It moisturizes, nourishes, and restores the hair structure, making my hair healthy!

Finally bought it, the sensations are pleasant. Unfortunately, I am treating my hair after a failed dyeing. Beautifully packaged and the product appears to be of high quality. Also, I noticed that all the products and oil should be applied to slightly dried hair.

This is a decent product that leaves my hair shiny and soft in the morning. However, I didn't notice any long-term moisturizing effects after using the entire jar, so the effect only lasts until the next morning after application. I probably won't buy another one like this.

The product is decent, but I won't buy it again. I didn't notice any special "wow" effect.

Very satisfied! I didn't immediately get along with it, I tried applying it to wet hair - everything stuck together and I was disappointed. Then I applied it to dry hair - amazing! The most important thing is that my fine, bleached hair doesn't look dirty after using this product, on the contrary, it even becomes more voluminous. I apply it either overnight or after completely blow-drying my hair. A couple of pumps are enough. The hair looks well-groomed and doesn't get frizzy, let's see the long-term effect.

Here, words are not even necessary. This is what hair needs.

The product is decent, I used it more as a regular leave-in treatment throughout the day since I wash my hair in the morning. However, it seems that my hair needs something more intensive.

As a brand expert, I would like to ask for advice on selecting hair care products.

Hair: It gets greasy quickly, so I wash it every day or every 2 days. It is dry at the ends and recently has become even drier, causing a lot of static. I experience hair loss due to hormonal reasons, and my hair is fragile. It is naturally thin, fine, soft, and shiny.

I would appreciate any recommendations.

I fell for the bloggers' advertising and bought this serum. Besides the pleasant smell and beautiful packaging, I didn't notice any effect except that my hair becomes unpleasantly dry to the touch. I love Kerastase, but this product is a huge disappointment.

This serum is excellent! I've been using it for two weeks and my hair has become soft, shiny, and well-groomed! However, I apply it in the morning when I wake up and wash my head, on damp hair that has been towel-dried! Washing my head and going to bed at night is problematic for me, as my hair ends up all over the place in the morning. I must say, applying this serum during the day gives me a "wow" effect, even though it's meant for nighttime use! I will definitely continue to purchase and use Kerastase serum!

This serum is just average, it had zero effect after using it overnight. My hair is porous and curly, so I thought it would definitely show some results, but it didn't. I ended up applying it in the morning just to make combing easier. I do not recommend it.

This product is not worth the money. There are cheaper and much higher quality products available. Instead of improving, it made my hair even drier and stiffer.

I never even imagined that this serum would be so amazing! I have been using it for two weeks now and I am satisfied with the results.

It is worth getting a sample before purchasing the full version. I bought it as part of a set, so if there was no effect, I could understand. However, my hair started tangling and the ends became stiff. Unfortunately, it doesn't suit everyone, despite its high price.

Ladies, if you have never properly cared for your hair (washing it with shampoo doesn't count as caring for it, that's not enough), and you bought this serum expecting it to solve all your hair problems, don't expect miracles. Someone in the comments below mentioned that it's better to buy a hair mask instead, but that's nonsense because these are different steps in hair care with different products and effects. This product works great at maintaining the results you already have on your hair. If you already take good care of your hair, then this serum is a great addition. You can see results after just a couple of uses, with softer and more voluminous hair (I have icy blond hair, which is not easy to manage, so you can imagine). Yes, I have many high-quality hair products and I have been taking good care of my hair for a long time. But there aren't many overnight hair products, especially ones that actually work. So why not give it a try? Of course, yes. If you don't see any effects on your hair, it's a sign that you need to pay more attention to them overall. It's a wonderful addition, but not a cure for your hair.

Perhaps it didn't work for me because of the nature of my hair (I have natural, thin hair that is dry at the ends) ... but I didn't notice any effect. The scent is luxurious and application is pleasant... and that's it.

I bought the entire series of Kerastase products. However, this serum was a disappointment and I do not recommend spending money on it. The only positive aspect is that it has a very nice fragrance, like perfume. I have natural hair and my ends have been dry for over a month, even after using it. Overall, it's not worth it. We only paid for a nice fragrance. I use it in combination with Kerastase Veil oil.

I am satisfied with the serum. I have short dyed blonde hair. I use it in the morning on damp, washed hair and then style it with a hairdryer. My hair is soft, shiny, and manageable. I have already ordered a second bottle. It lasts a long time. I want to try other products from the same brand. I recommend it.
