Kérastase Nutritive Nourishing Hair Serum with Niacinamide, Overnight Leave-In Treatment for Dry Hair, Lightweight and Non-Greasy, 8H Magic Night Serum

I absolutely adore this product and wouldn't be without it. It comes in a stylish, quality glass bottle. I use the product on my waist length, naturally wavy hair. It works well to nourish my hair and tame frizz. I know it's an overnight treatment but I use it as and when I need it. It doesn't feel greasy at all and seems to soak right in creating a smooth and hydrated feel to my hair. I've been using this product for a while and I think it helps prevent breakage and promote hair growth and strength. It smells amazing too which is always a bonus. If you're looking for a hair product that will nourish your long locks, without being greasy and that smells divine then this is the product for you. Yes, it is expensive but you don't need loads and it seems to last a long while. I think it's worth every penny to keep my locks in tip top condition. It took me a fair while to grow my hair long and this product helps to keep it strong and stay long.

If you have dry, dull, or frizzy hair, stop what you're doing and try the Kérastase Nutritive 8H Magic Night Serum – it's truly a game-changer! I've been using it for a few weeks now, and I'm genuinely blown away by the results. The idea of an overnight leave-in treatment for hair was intriguing, and this serum delivers on every single promise. I apply a few pumps to my mid-lengths and ends before bed, and the first thing I noticed is how lightweight and non-greasy it is. There's no residue on my pillow, and my hair doesn't feel weighed down at all. But the real magic happens overnight. I wake up to hair that feels incredibly soft, smooth, and deeply nourished. My dry ends are visibly healthier, and my hair looks shinier and far less frizzy. It truly feels like my hair has had a full 8 hours of restorative sleep! The inclusion of Niacinamide seems to be working wonders for improving overall hair health. It also has a lovely, subtle scent that's very pleasant. While Kérastase is a premium brand, a little goes a long way, making this bottle last. If you're looking for an effective, luxurious, and easy way to combat dry hair and wake up with gorgeous, manageable locks, this 8H Magic Night Serum is an absolute essential. Highly, highly recommend!

Really nice feel after ising this.

I'm already a big fan of the brand, but I love this. I lighten my hair, so I'm conscious that it always needs moisture. I apply every night and my hair is smooth and silky in the morning. I feel like there is less frizz - especially when combined with a silk pillowcase. My favourite thing is that it doesn't feel heavy or greasy - it just works right into my hair seamlessly. And, as an added bonus, it smells delightful. The price did make me wince, but you get a lot of product for that, and you only use a small amount each time, so let's do the maths! If we assume that each pump is 0.25ml (thanks Copilot), then that's 360 pumps per bottle. It suggests you use 1-2 for short-mid hair or 3-4 for long - depending on texture, so let's go with the average: 3 pumps, that means it will last 120 uses - or roughly 4 months, and the price per day/use is about 33p. So actually, it's really not that bad at all.

I love this product, although I do prefer the blonde one they do. Only slight downside is the price I wish this was cheaper! But it does the job and my hair feels great the next day, I try to only but when it’s on sale.

OK, so this stuff is brilliant. I have hair that does NOT want to be bleached, however I persist in bleaching it and inevitably suffer from breakage. I recently bought this after going blonde again, and it has been an absolutely gamechanger. My hair is the healthiest it has EVER been post-bleaching. I run a squirt or two of it through my hair at bedtime, concentrating on the front of my hair where I tend to get the most breakage. I also occasionally run it through my hair during the day to smooth it out a bit. My hair tends to look greasy when I apply other moisturising products, but it just drinks this in and doesn't mean I have to rewash/restyle after application. I've been using it for just over a month and I'm about halfway through the tube, so I've just ordered a second one on the Black Friday offer. Yes, it's more expensive than other options, but it is significantly better than anything else I've tried (and I've tried a silly amount of products). Even at full price, paying £25-ish quid per month to stop my hair from being entirely frazzled is worth it to me. I can't recommend enough, I'm just annoyed that. It's so good I'm now commited to using this product for life 😂 PS there is a specific version of this for blonde hair, but my hairdresser warned me that if you prefer warmer tones in your hair, the other one will bring out silver tones instead (similar to purple shampoo). So the other version is probably better for cool blondes, but if you're like me I would stick to this one (or risk having to re-tone your hair more regularly).

So worth the money. Lasts months. Has helped stop so much breakage and my hair’s grown the longest it ever has.

Smells really really nice, and you can see that your hair looks smoother and my split ends. Don’t look as bad after I put the oil in even in the morning. My hair doesn’t look dry and it still feels soft. I recommend this hair oil over any others because it has a restorative power in it and always keeps my hair looking shiny.

O nome dele nao mente é absurdo, parece milagre divino. Meu cabelo tem química, fiz descoloração e tinta, quando passo o serum, no momento da aplicação, ja fica outro cabelo, no outro dia parece mega hidratado e o brilho é de outro mundo. Eu amei ele e vale cada centavo, qualquer cabelo vai ficar incrível com ele e vou economizar pra comprar mais quando acabar. Único ponto negativo e que acaba muito rapido, nao rende muito, mas como eu disse vale muito a pena o cabelo fica de propaganda e o efeito e na hora, juro que parece magica queria conhecer ele a mais tempo.

Great product. I immediately noticed a difference as my hair became softer and did not tangle as much.

Das Nachtserum hat mich überzeugt. Es lässt sich einfach auftragen, beschwert die Haare nicht und sorgt über Nacht für ein gepflegtes Haargefühl. Am Morgen wirken die Haare geschmeidiger, glatter und haben einen schönen Glanz. Besonders bei leicht trockenem Haar macht das Serum einen sehr guten Eindruck. Zudem ist es sparsam in der Anwendung und duftet angenehm. Insgesamt ein hochwertiges Pflegeprodukt, das ich gerne weiterempfehle.

Its not original and im so upset as i paid all this amount for a fake product

Repeat order. It's a fantastic product. Leaves my hair nourished and shiny.
