No Results
[This review was collected as part of a promotion.] I bought this product with high hopes after reading several good reviews, but unfortunately, I didn’t see any changes at all. I used it exactly as instructed for several weeks, and my hair looks and feels the same. Not even the slightest improvement in texture, shine, or growth. I feel sad and disappointed because I really wanted it to work. Maybe a hair oil or a different treatment would work better for me. This one definitely didn’t.

Actually magic
[This review was collected as part of a promotion.] The serum is lightweight and non-greasy, which is a big win. My hair usually gets weighed down easily, but this absorbs quickly and doesn’t leave any residue on my pillow or hair in the morning. It feels more like a hydrating leave-in treatment than an oil or cream.

I love the way it makes my hair feel soft and it's been helping with my flyaways. I've used it after a shower and after a style.

Highly recommended
[This review was collected as part of a promotion.] I’ve never used an overnight hair serum before, but I’m familiar with leave-in conditioners and various hair repair treatments, so I have a good basis for comparison. I’ve applied this serum a few times—once on dry hair and twice on damp hair before going to bed. The scent is quite luxurious, like a high-end perfume, and the texture makes it easy to distribute through the hair. However, I didn’t notice a significant difference in how my hair looked or felt after 8 hours compared to using a more affordable leave-in conditioner. While my hair felt soft and detangled, it didn’t seem any less damaged or visibly improved. Love the stylish packaging as well its feels luxurious.

Nourishing but heavily scented
[This review was collected as part of a promotion.] Used every other night for a few weeks, and my hair looks shinier and stronger. The formula is like a creamy gel, and is heavily scented (very floral, be advised!). I wish it were a little less scented, but it definitely helps to nourish dry and brittle hair.

This serum has won me over!
[This review was collected as part of a promotion.] I don't like weighing my hair down with too much product & didn't think I needed a serum. I was SO wrong. This serum absorbs right into your hair and the results are immediate. My hair is smoother, softer, and frizz is gone. Using it over time, it seems to nourish my hair. I'm 67 years old and my hair looks better than when I was younger. This serum is the one product I didn't know I needed!

Truly Magical- Woke up to Softer, Silky Hair
Truly Magical – Woke Up to Softer, Silky Hair!
The Kérastase Nutritive 8H Magic Night Hair Serum is hands down one of the best overnight treatments I've ever used. As someone with dry, frizz-prone hair, I’m always on the hunt for products that deliver deep nourishment without leaving buildup — and this serum delivers on every front.
The texture is lightweight and non-greasy, absorbing beautifully into the hair without transferring onto pillows. I apply a few pumps to the mid-lengths and ends before bed, and by morning, my hair feels incredibly soft, smooth, and nourished — as if I just left a salon.
What sets this serum apart is how effortless it is: no rinsing, no mess, and no need to style in the morning if you don’t want to. It also smells amazing — a subtle, calming scent that makes your nighttime routine feel like a luxury spa experience.
After a week of use, I noticed my hair looked shinier, felt stronger, and was way easier to manage. It’s like beauty sleep, but for your hair!
If your hair needs hydration, repair, or just a little extra love while you sleep, this product is a must-have. Total holy grail status.

Good but hate the scent.
[This review was collected as part of a promotion.] I was super excited to try the Keastase 8h Magic Night Hair Serum cause I have heard to many good things about it. The packaging is beautiful and feels luxurious in its glass bottle. The texture is very much a serum like you would expect from a skincare product. It left my hair feeling hydrated but not greasy and extremely soft in the morning. I personally really HATE the extremely strong floral scent and found that my 3c curls drank this right up which resulted in me having to use much much more product than the recommended 1-2 pumps so get even distribution throughout my hair despite the product having a very nice texture and spread. For the price and quantity needed for my hair texture I don’t think I could justify the repurchase.

Luxurious
[This review was collected as part of a promotion.] I’m obsessed with this: I’ve been using it most nights before bed, and it’s made my hair softer and less frizzy. I usually have a lot of frizz around my face and on top of my head, but this has reduced that. My hair also feels silkier.
On top of all that, this product feels luxurious to use. The packaging is glass, and the scent of the product is one of my favorite things about it. It smells like a soft floral that I can’t quite place, but I adore it.

Best to fix dry hair
[This review was collected as part of a promotion.] I love this Kerastase Nutritive 8 hour magic night serum is a gift from heaven. I have superdry hair so, to use this at night and wake up in the morning with my hair so soft and smooth and shiny is amazing.

Softest hair ever!!!
[This review was collected as part of a promotion.] I received a free sample and used it for a month. I noticed a significant change in my hair, so I decided to purchase the full-size product. Without it, my hair doesn’t feel the same. It feels soft and less frizzy, even when I just wake up. Since I have naturally frizzy hair, I appreciate how much less frizz I see now.

Magic? Yep.
[This review was collected as part of a promotion.] Really is magic! Kerasaste does no wrong! This helps my hair and I love that it works while I’m asleep. Perfect for someone who showers in the morning in case you get too close to the root.

Doesn’t weigh down fine hair!
[This review was collected as part of a promotion.] This Keratase Magic Night Hair Serum absorbs into your hair very quickly! If you have a lot of hair, you’ll probably need more than one pump. It’s lightweight enough that it doesn’t weigh down fine curly/wavy hair like mine, which is nice. My only problem with it is the scent is very strong and very perfumy. So if you don’t like strong smells, especially at bedtime, you might not like this one. Otherwise, I think it’s a good product and will probably last a long time so it’s a good value.

you see the result after the very first use
[This review was collected as part of a promotion.] Okay, you need to try this. It’s the Kérastase 8H Magic Night Serum—basically a leave-in treatment you put on before bed, and it works while you sleep. I did’t expect much, but I swear, I woke up with softer, smoother hair without doing anything.
It’s packed with good-for-your-hair ingredients like iris root extract for deep hydration, a blend of vitamins (E, C, B3, B5, B6) to strengthen and add shine, and nourishing lipids that help smooth and protect your hair overnight. Plus, it’s free of sulfates and parabens, so it’s gentle and safe for color-treated hair too.
And It’s super lightweight—not oily or heavy at all—and it doesn’t mess up your pillow. I just run a few pumps through my ends at night, and by morning, my hair feels so much more manageable. Like, I actually look semi-put together without trying.
And the smell? It’s subtle but really luxe—kind of spa-like. If your hair’s feeling dry or frizzy or just meh lately, this stuff is a game-changer, especially after Brazilian highlights coloring. Total lazy-girl luxury.

A great hair serum
[This review was collected as part of a promotion.] I have been using this product nightly for a few weeks. My expectations were a bit high, given the word ‘Magic’ in the product title. I wouldn’t necessarily call it a magical hair serum. However, it’s a really good one! My hair has felt healthy and smooth, perhaps even having a bit more shine. I had previously used hair oils at night, but this serum consistently absorbs better compared to an oil. Bonus points for it smelling so good, too! A little bit goes a long way. I use one pump and the bottle seems to be lasting.

Good but strong scent
[This review was collected as part of a promotion.] I received this product for free from Influenster and Keratase in exchange for my honest review. This overnight serum has my hair feeling great in the morning, but the scent is pretty strong.

Love this serum – lightweight and truly magic!
[This review was collected as part of a promotion.] I liked the Kerastase 8h Magic Night Hair Serum from the first use. It has a pleasant, lightweight texture that isn’t oily, which is especially important to me. The product absorbs quickly, doesn’t leave any residue on the pillow, and doesn’t weigh the hair down. The scent is light and clean, not overpowering, so it’s comfortable to use before bed.
After a few uses, my hair felt softer and less frizzy. In the morning, it looks more well-groomed and is easier to brush. It’s a good option for overnight care if your hair is dry or needs extra hydration.
The packaging looks nice and feels high-quality, with a convenient pump that makes it easy to apply the right amount. As for the price, it’s definitely not the cheapest product, but considering how well it works and how long it lasts, I think it’s worth it. Overall, I’m happy with the results and would recommend it to anyone looking for a light night serum without a greasy feel.

Works Hair Magic While You Sleep!
[This review was collected as part of a promotion.] I was excited to try Kerastase 8H Magic Night Serum! This stuff works like magic, just like the name says! I’ve used this on my hair dry and damp before going to bed. I used one pump and smoothed into my ends. First of all it has the most luxurious, clean, delicious smell! You won’t be able to stop sniffing your own hair! It instantly made my hair feel smoother, softer, and more hydrated! I love that it also works while you sleep, as an awesome added bonus. I think this would really be good to use anytime though! It’s a very lightweight serum and did not make my hair feel heavy or greasy at all. I definitely recommend!

Great addition!
[This review was collected as part of a promotion.] This product is going on my shopping list permanently. I have seborrheic dermatitis and whenever I use products to soften my hair it tends to cause problems for me due to certain oils in them but not this product. In the last 33 days I've used this overnight hair treatment and I haven't found a single negative reaction. My hair hasn't felt this soft in a long time. I know I have a lack of hair on my head but I've grown it out to test this product and I'm loving the results. It doesn't leave residue on my pillow nor does it have an oily feeling left behind. On top of it all, it smells absolutely amazing. Finally a product to soften my hair without causing itch or seborrheic dermatitis flare ups. Highly recommend trying this yourself. Worth the price.

[This review was collected as part of a promotion.] I received this product in exchange for my honest review: This product has helped take my hair from dull and frizzy to shiny and smoother! The packaging is high quality and it smells great! It is easy to apply and didn’t weigh down my thin hair. However; I don’t believe the price is worth it. There are other similar products on the market that are cheaper with similar effectiveness.
