Great product but like the day version better

The consistency was a cream which was unexpected. It works but like the day version better.

lifesaving hair serum

This is a life saver! I have fine, thick hair that tangles a lot. I put in a Google search about my hair texture and the Magic Night Serum came up. I am just sad that I didn't find this sooner! I LOVE it. I use it before bed on dry hair, as a leave in conditioner out of the shower, to tame flyaways, etc. My hair looks great even two days without washing it. And most importantly--no tangles or knots!!

must have for soft & healthy hair

as someone with super fine, color treated hair who is trying to fix damage and dryness, this product has been a life saver over the past 3 weeks I have implemented it into my night routine. I’m so happy with this product and the results I have seen in such a short amount of time. My hair already seems to be so much healthier, softer and more hydrated. I can’t wait to see my results over more time and consistent use!

[This review was collected as part of a promotion.] I absolutely love this stuff! A little bit on the ends of your hair at night and maybe a little wiping over the hands on your hair the rest of it, and you wake up with silky, soft hair, not frizzy The stuff is amazing. I use it during the day too if I need to freshen up my hair a little bit.

Just wow

This serum changed my hair drastically. I have super dry, frizzy, long thick hair and this has done wonders for me. It is pricey but it's so worth it. PLUS, it smells amazing I use it at night and morning too only two/three pumps are needed. JUST GET IT.

I’m not sold

It’s very messy and for that reason hard to get on your scalp. I would say it does make my hair appear a bit greasy.

Originally posted on  kerastase-usa.com

AMAZINGGG

I love this product so much! I’ve seen so much improvement with my hair. The ends of my hair actually feel the same as my mids and top which is amazing. It’s such a good hydrating serum and I will continue to re-purchase. It just feels like such a luxurious nighttime routine.

Pretty Good!

Pretty good, i usually apply this every other night, and wake up with very soft hair. But i feel like my heavier oils can do the same in terms of softness and strengthening. But i do really like this just prob wouldn’t repurchase.

Luxurious leave-in treatment

[This review was collected as part of a promotion.] I already ordered my second bottle before my first bottle was finished. I have really dry hair, especially the ends. The 8 hour leave-in treatment leaves my hair noticeably softer and smoother. It truly is hydrating and the scent is really mild. I’m not sure why people mention it’s a strong scent. I have fine hair and it’s not too heavy.

Originally posted on  kerastase-usa.com

Soft Hair! Smells so good!

I love this night serum so much! This is the first kerastase product I purchased and I have already purchased other products since. My favorite haircare brand now. This serum leaves my hair so soft and my ends look so good I wish I knew about it sooner! I have high porosity hair and it soaks this serum right up. It’s not heavy or greasy at all. I’m African American with type 4 curly hair and these products have really made my hair more manageable in it’s curly state and when I straighten it out.

Originally posted on  kerastase-usa.com

Like this product

[This review was collected as part of a promotion.] This is a very fragrant serum and smells so good. I love to sleep with this smell. My hair became glossy and smooth after I used it for half a year.

Did not work on low porosity hair. Turned brittle

It made my hair dry and brittle, possibly bc I have low porosity hair. It does smell very good though but I feel like I wasted a lot of money since I bought another product as well.

Originally posted on  kerastase-usa.com

groundbreaking. amazing.

Possibly one of the best hair products I have ever used. I love how easy it is to throw this on at night and wake up with perfect, smooth hair (highly recommend using with a satin/silk cap or pillowcase). I have very thick hair but don't need to use much, so the bottle lasts a long time.

Originally posted on  kerastase-usa.com

Great product!

I am very happy with this product and among all, this is my favorite Kerastese serum. It smells wonderful, my heart feels silky and so alive, and looks great after applying this serum. Highly recommended!

Game changer!

[This review was collected as part of a promotion.] The Kérastase 8H Magic Night Hair Serum is an absolute game-changer for hair care! This overnight serum truly lives up to its name, delivering incredible results while you sleep. The lightweight formula absorbs beautifully into the hair without leaving any residue or greasiness, making it ideal for all hair types. After just one use, my hair felt noticeably softer, smoother, and more hydrated. It’s enriched with nourishing ingredients like iris root extract and vitamins, which work wonders in taming frizz and repairing damage. By morning, my hair looked revitalized, with a healthy shine and improved manageability. What I love most is its convenience—it takes seconds to apply and doesn’t require rinsing. Plus, the subtle floral fragrance is luxurious and calming, making the nighttime routine feel indulgent. Whether your hair is dry, damaged, or just needs a little TLC, this serum is a must-have. It’s like giving your hair a spa treatment every night. Highly recommend!

No more bed head rat's nest in the mornings

The Kérastase 8H Magic Night Hair Serum has been a game-changer for my haircare routine! It’s the perfect extra step to help extend my style between washes. Since I started using it, I’ve been able to go an extra day without washing my hair, which is such a time-saver. One of the biggest improvements I’ve noticed is how much it reduces bedhead and frizz. My hair used to look a bit wild in the mornings, but now it’s noticeably smoother and more manageable. The serum feels lightweight and doesn’t leave any residue, which is a big plus for me. Overall, it’s a fantastic product that does exactly what it promises. If you’re looking to keep your hair looking fresh and polished for longer between washes, I’d highly recommend giving this a try!
