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!

This hair serum has changed my hair for the better. I have straight hair but suffer badly with frizz, and after a week I've noticed such a difference already. I apply it before I put my overnight curler rod in, and my hair isn't as frizzy in the morning and is noticeably shinier and softer. Would definitely recommend!

My go too, absolutely gorgeous smell & makes my hair feel sleek, shiney and glossy

It looks authentic although it's my first time purchasing the serum. I can't speak for long term benefits but I do wake up with softer hair and seems to help a bit with frizz. I got it on discount -and would probably purchase again but not full price.

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).

This stuff is amazing, I’ve been through five bottles and my hairs health has improved majorly, it smells amazing and I always get compliments for the smell of my hair, my hair has felt softer even after not washing it for five days

Fantastic product love it it’s expensive but so worth it !

المنتج مش اصلي عباره عن مايه بريحه

Só comprem! Não entendo o porque desse item da Kérastase não ser mais viralizado do que todos os outros porque ele faz milagre desde o primeiro uso, sem falar no cheiro! Vale cada centavo e ainda arrisco dizer que vale mais do que comprar até mesmo as máscaras da linha. Na foto foi após a primeira noite de uso. Cabelo quase sem frizz mesmo tendo passado a noite em atrito com o travesseiro, extremamente macio e sem ter feito nenhum uso de prancha ou escova. Vale lembrar que o meu cabelo é fino, sobre com queda e quebra e consequentemente muito muito muito frizz. Jamais vi um produto igual a este!!
