Nutritive 8H Overnight Serum

Love!

[I received this product in exchange for my honest review] I really enjoyed this serum! It smells so good and makes my hair feel so soft the second I put it on. I have not seen a tone of change in my hair but I can tell it’s shinier when I use it. The pump at the top is so helpful and gives a lot of product.

This is a solid container (nice heavy glass), and easy to use (though - be careful using it right out of the shower because, well, it’s glass 😂). Overall it seems to be a good value for what you pay for - a little will go a long way here, you don’t need a lot of product to get the job done. So far, I have no complaints about it!

I’ve been using the Kérastase 8H Magic Night Hair Serum for a few weeks now, and I’m honestly impressed. I just apply a pump or two before bed, and by morning my hair feels so much softer and smoother. It doesn’t feel greasy at all, and I love that I don’t have to rinse it out. It’s helped a lot with dryness and frizz—my hair looks way healthier overall. It’s become a part of my nightly routine, and I can really see (and feel) the difference.

Divine serum

[I received this product in exchange for my honest review] Keeps my hair soft, shiny and healthy. It smells so good, absolutely delicious. It absorbs quickly, doesn’t weigh my hair down. Two pumps of product is enough for my long hair.

Game changer

I thought it was just publicity but is really good serum , love the texture that lets in my hair and it did improve the fiber health a lot

Just magic!

[I received this product in exchange for my honest review] I’ve been bleaching my hair for years, so it’s pretty damaged and needs regular care. I decided to try this Kerastase product, and honestly, I was impressed. After the first use, my hair felt way softer and smoother. It looked shinier, and the frizz and static were pretty much gone. You don’t need a lot, I have long hair and just 2–3 pumps are enough. If you use too much, it can make your hair look greasy, so I try to be careful with the amount. I also really like that you don’t have to rinse it out — super convenient when you’re in a rush. The scent is amazing. People keep asking me what perfume I’m wearing, but it’s just this product. I’ve been using it for about a month now, and my hair feels stronger and not as brittle. Definitely helps if you're trying to grow your hair out.

Loving this product ! Been using consistently for about a month and love it so far ! I have curly highlighted hair and this has helped so much maintain its integrity. Will definitely repurchase

[I received this product in exchange for my honest review] The kerastase 8 hour magic night hair serum is amazing! This helps my hair smooth and moisturized. This is the best serum for your hair and a little bit goes a long way. I actually love the smell of this and it’s in a glass bottle. I highly recommend this bottle for your hair.

A Game Changer for Dry Hair!

[I received this product in exchange for my honest review] I've been using the Kerastase Nutritive 8H Magic Night Serum for a few weeks now, and it has completely transformed my nighttime hair routine. I have medium-thick, wavy hair that tends to get dry and frizzy—especially overnight. This serum has made a noticeable difference in how soft, smooth, and hydrated my hair feels when I wake up. First off, the texture is lightweight and non-greasy, which I love. It absorbs quickly into the hair without leaving any residue on my pillow, and there's no need to rinse it out. I apply 1-2 pumps to the mid-lengths and ends before bed, and by morning, my hair feels silky and manageable, with zero crunch or stiffness. What really impressed me is the frizz reduction—my hair used to puff up by morning, but now it looks polished and smooth without any heat styling. It also makes detangling a breeze, which has helped reduce breakage significantly. And let’s talk about the scent—divine. It’s a clean, floral fragrance with a warm base that makes it feel like a luxury spa treatment before bed. Not overpowering, just elegant. This is a must-have for anyone struggling with dry or damaged hair. It’s an overnight miracle that lives up to its name—hydrating, strengthening, and leaving hair noticeably softer and shinier by morning. The price is on the higher end, but a little goes a long way, and the results are absolutely worth it.

Good for frizz

[I received this product in exchange for my honest review] First impression of the serum is that it is light in texture with very quick absorption. The smell is really nice and light. It smells like conditioner. I found that the serum didn’t really change my hair in terms of softness, but it did help to somewhat tame the frizz. I would recommend it for that purpose. This review was written in exchange for the product.

Instant Repair

I am always nervous to try a leave in product on my hair since it tends to run oily after a day or two. This did not leave it with any additional oil and was an instant win when it came to repair. The ends felt soft the next day and I was able to use it multiple times in a week. I used two pumps since my hair is so long but the product itself went a long way when it came to coating each strand. My only problem was how perfumed the product was but I enjoyed the scent the next day after it had a chance to dissipate slightly.

Overall very luxe hair care!

This product definitely smooths my hair and makes it way less frizzy and super soft. The smell is very luxe and bottle is sleek. It doesn’t leave my hair feeling oily or greasy which is a big bonus!
