Nutritive - Sérum de Nuit 8h

Made my fine, thin, straight hair feel worse

This definitely works for only certain hair types and whatever hair type that is, I don’t have it. I would say that I have pretty fine, thin, straight hair. I’ve heard this from other reviews, but it made my hair feel like straw, and it felt like I could feel the end of every single strand of hair. It did not make my hair feel soft whatsoever and I didn’t see any visual improvements either. I even used half the bottle because I wanted to make sure that I was giving it a fair and true chance, and it only made my hair worse unfortunately. Obviously I really wanted to like it because I paid full price for it, and I love other Kerastase products. This one just didn’t work for me.

Makes your hair SO smooth

Minus one star for how expensive it is, but it genuinely works so well. I love to use on damp hair out of the shower on heartless curls or for braids and it always comes out so pretty

A must have!

Amazing product! After having my hair racked by a bad hair dresser it’s been hard to find products that tame this monstrosity of frizz ball I’ve been left with. Before and after photos of using this product…a few hours in between inbtween

I will be buying this for the rest of my life.

I can wholeheartedly tell you that this is one of the products that is completely saving my hair. A little tip: Instead of applying it from the mid-lengths to the ends with all your hair together, separate your hair into large sections and apply a small amount to each section only from the mid-lengths to the ends, then braid it as directed. After braiding, I add another little bit just to the ends. This product is absolutely wonderful, and you'll want to use it for the rest of your life. I started my journey to take care of my hair completely—in the sense of really caring about what I was putting on it—two months ago. My hair is very fine, very brittle. I can't say it's dry, but it's the kind of hair that if I don't drink enough water or don't hydrate it enough, it will really show, especially on the ends. Before applying it, if I braided my hair, the ends at the end of the braid were stiff, completely straight, and you could see all the dryness and damage. The next day after applying this serum, my ends were so beautiful, I couldn't believe it. They formed a beautiful spiral, as if I had literally woken up with the healthiest hair on earth. My entire hair feels so hydrated, silky, and healthy. I hope you can feel what I felt with this product, and I'm someone who was disconnected from my hair for a long time. Buy it; you won't regret it.

a literal must have buy it rn

this is an absolute masterpiece of a product, there is nothing bad i could ever say other than the price but oh my lordy it’s worth every cent. not only does it smell like actual heaven it’s made my hair so soft, i’m in my hair care era right now and this is the only product that sticks out to me. i stg you don’t need anything else just this bad boy😌

Must have

Absolutely the best night serum , got this for my birthday gift and it has made my hair soft, feels moisturized and adds volume, from getting my hair damaged from multiple balayages it has made my hair feel alive . I go to sleep with this product and with a bun and by the morning my hair feels so alive, 10/10 recommend .

Helps Tame Frizz

After using this product consistently throughout the last few weeks it’s safe to say it works for high porosity hair when used on damp hair and is air dryed. I find my hair feels it’s softest and doesn’t have as much frizz!

Been using this product for a few months now and honestly just disappointed. I don’t find it to be very hydrating at all. I like the smell a lot but I don’t think it does anything to my hair. Feel like you need to use a lot to even feel like the product is doing something.

Must have for nightly routine

This Kérastase serum makes my hair feel so soft and healthy by morning- no greasiness, just smooth, hydrated strands. Smells amazing and works like magic overnight. Definitely a staple in my routine routine now!

Works so well but I HATE scent

I love what this product does for my hair. I use two pumps after air drying and then put in a heatless curler “unicorn style” for sleep. I spread half a pump in my hands when I unwrap in the morning and it leaves my hair soft and moisturized without any oily feeling. I have to deduct points though because the scent is horrific to me. I literally must follow up with hair perfume or I will be disgusted by my own scent. Who decided to choose floral moth ball scent for this?!

only use sparingly

the treatment made my hair smell good but it's a little heavy to use all over the hair. I recommend only using on the ends.

My favorite hair product

I will admit I’m a girl who loves her hair products already to begin with. One large pump of this stuff in my hair when it’s wet and it leaves my waves feeling so soft and beautiful! It smells amazing as well! I love it
