never makes my hair greasy!! keeps it soft and somehow doesn't add any weight. 1000% worth the price

I love everything about this serum. My scalp feels so good!

If you’re thinking about this one, just DO IT, the smell is amazing, and your hair will never be softer.
So happy this was recommended to me, it’s helped my curly hair so much, the moisture and healthy hair feeling makes it worth every penny!

It truly is magic!!! I’ve never had a product that has made my hair SOFT before! I have really thick naturally curly hair that is unruly and this serum tames it while keeping my hair feeling fresh, it doesn’t add any weight or greasiness.

Literally the BEST product ever!!! Put this in your hair over night or even after you’ve styled it. First it smells amazing! But most importantly it leaves your hair feeling so smooth and soft!

You won’t regret it!! BUY IT!

I originally had bought a bundle that included this and i FELL IN LOVE. had to rebuy it. it smells great, feels great and my hair is oh-so-soft. I even use it during the day. i just use it all the time. Makes my hair feel healthy and look/feel soft

Obsessed! My hair is so shiny and soft after using this!

Buy this!! You will not regret it, nor will you ever be able to live without it.

I have thick/wavy hair and always used to wait up with knotty/kinky hair in the morning and would have to re-do it every day. When I use this night serum my hair is just how I left it the day before. It feels so soft and healthy in the morning. And to top it off the scent is amazing!!

Scent is too heavy, ruins the whole experience. Especially for sleeping. So disappointing!

I love this product most for its anti-static properties, but I’m not sure if it’s a product I’d repurchase. I know they recommend using this product with the Elixir Ultime Oil (which I did), but I actually find that the Elixir Ultime Oil is all around more effective for my hair (fine wavy hair but long and thick - prone to frizz). I still think the Serum is a good product though. One thing to note: the scent is good but very strong, so if you are sensitive to smell, beware. In general I wish the Kerastase scents were less potent because it becomes a lot when you start layering different products that all have very strong but different scents.

It's worth every penny. I saw an IG story where Nicole went to Ontario and said everyone in Ontario needs this serum because it gets so dry here in winter. My hair always feels like straw a couple of days after washing, and it's even worse in winter. In rolls this serum. I put some in and TWO strangers complimented me on how healthy my hair looked. It feels so lovely, light, and soft when I use it. I put it in at night and occasionally before going somewhere during the day if it feels a bit dry. Definitely worth it if you want feathery, hydrated, soft hair.

Was nervous to use this product at first, thinking I’d wake up with greasy hair from product going on.. I was wrong! My hair ended up looking fresher and feeling softer in the morning after using this. I’ve also found this in combo with the elixir ultime oil, has saved my hair from winter static - no more “did you touch the electric ball at the science centre” looking hair 🙌🏼

It’s too soon to see the impact it has on my hair but if anything, BUY IT FOR THE SCENT! Seriously soo dreamy

It took me a while to finally order this product and I am kicking myself for it. I have long brunette hair and my hair had become so much more manageable day after day between washes. It adds shine, smoothed out flyaways and adds some extra moisture. This is quickly becoming a new favourite of mine

This is a solid no for me. Again another product I so wanted to love. But for those of us that have fine hair this does absolutely nothing. Solid pass

I have always avoided sleeping with wet hair until now. This makes my wild, crazy, frizzy, tangly hair feel so soft and manageable, and I end up with cute waves in the morning that smell amazing. Hooray!

I alternate between this and the cicanuit. I love them both. My hair feels great and smells even better.

Love this night serum, first time using a night product and I find it holds my style through the night more reduces waves and curls on straight hair and has helped with winter static and dryness.

A must have. The best smell, the best product. I bought this at the beginning of the year and I have not gone a day without it. Not greasy what so ever I put it on my dry hair every night and in the mornings, or whenever I’m feeling a little extra dry, especially in these winter months. A staple in my routine !

Used the sample and immediately order the full size. 5+ stars !

One of my fav products by far. Not only does it smell amazing, it really works. Tames my minor frizz after a blow dry but I use it thr most after a long hot day at the beach it calms my hair and restores it right back to the shiny look it once was!!

I’ve never used a product like this! Instantly my hair feels moisturized and soft without getting staticky. The fragrance smells so good and I swear I get a better night sleep because of it!

This is my absolute favorite Kerastase product! I use it every night and it makes my hair so soft and smells amazing! I have very fine hair and it does not weigh it down or make it greasy at all! Highly recommend!

I absolutely love this product. I use it everyday - sometimes twice a day when I feel like my ends are really dry. The scent is subtle and my hair feels so soft and shiny after use.

I can’t say enough about this product. If you had to pick one, pick this one!

Fantastic product. It smells amazing and my hair is so much tamer/softer when I wake up :)

My hair has never been sooooo soft! My hair has been so much more manageable since using it. Love love love this product and will definitely be repurchasing again when i'm close to running out

The best product I use! Every night and if I need a bit more in the morning.
The smell is also the best thing going.
My hair loves this stuff!

I wanted to wait a few months until a posted a review to really get a feel for this product. I have always been so concerned about using product and my hair getting oily between washes, but this stuff is magic! I have wavy hair that tends to get crazy while I sleep and I wake up in the morning with easy to manage, shiny hair. Seriously amazing. I've also used it as an air dry cream or used it to smooth out any frizz after throwing a few waves in my hair with my flat iron. 5 stars, must have, buy it if you've been thinking about it!

This stuff makes my hair so much more manageable in the morning and is so much softer and healthier feeling! It also helps to keep my hair styled the way I had it that day whether it be curled or flat ironed so thats an extra bonus! It also smells fantastic and its my new fav scent to fall asleep to

MAGIC is right! Love!

This product smells so good and my hair is so soft in the morning!

Makes my hair so soft in the morning! Scent is so comforting as well. :-)
