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

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 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.

Can’t recommend this enough. Have been trying both Kerastase and Olaplex shampoo and conditioners, also Kerastase elixir oil, which are all good but this one is a stand out hit. It makes my hair feel so soft and smooth with only a few drops on medium/long hair, and smells lovely. I have very fine hair and it doesn’t weigh it down or make it greasy - in fact I can go an extra day before washing it after using this. Of all the expensive stuff I’ve tried, this is the one I’ll keep on buying.

Very nice product. Wonderful scent. Helped with loss. But doesn’t last very long, so works out very expensive.

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.

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!

Has reallt helped my long think hair stop being frizzy and finally feel luxurious after years of bleach.

I’ve been loving this hair oil! It makes my hair feel noticeably softer and smoother without leaving it greasy or weighed down. Just a small amount on the lengths and ends gives my hair a lovely glossy finish and makes it look much more polished.

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.
