Miracle serum
[This review was collected as part of a promotion.] This serum works great! I have a tendency to have dry hair that splits easily and tangles. This works great to help my ends and prevent tangles.

This finally helped…
… take care of my split ends! Not to mention it also did a much better job on my frizzy areas, hiding them at least temporarily. I may be more excited about the latter!

Thank you for sharing your honest feedback with us. We are sorry to hear that you didn't see the transformative results you were expecting for your split ends. Because our reparative formulas are designed to seal the hair fiber and prevent further damage, the results can often be more subtle if you already have relatively healthy ends. In your case, the product may be working more as a long-term preventative measure rather than an instant visible fix. If you are looking for a more immediate change in your hair's appearance—such as added shine, smoothness, or hydration—we would love to help you find a range that better targets those specific goals. Please feel free to reach out to our experts at 1-877-254-9949 for a personalized recommendation. Thank you for giving Kérastase a try!

MAGIC in a bottle
[This review was collected as part of a promotion.] This product is literally magic. And it lasts FOREVER. You don’t have to use much, a little goes a long way. I have hand tied hair extensions, and I love Kerastase products, especially this one. It helps keep my extensions hydrated and smooth. I also use it when I want to touch up and smooth and second or third day style, without using more heat. Use a little of this and frizz and split ends vanish.

Instant results!
After years of color and straightening processing,this product instantly smoothed my damaged dry ends. I was skeptical initially as the product felt heavy, but my hair quickly absorbed it, and within within a couple of hours, the ends were smoother.and after a month there has been definite improvement.
I apply to my wet ends after I shampoo and condition and then reapply a tiny amount after my hair is dry. As I only wash my hair a couple of times a week, Additionally yes, ma’am
apply some of the serum to the ends and brush through several times between washes. And it smells so good.

Still a staple but miss the OG formula
[This review was collected as part of a promotion.] Transparently I liked the old formula a bit better, but I still use this consistently and it’s become a staple for me. It’s super easy to apply (I recommend wet hair vs dry) and the oil texture smooths through my hair without it feeling too heavy. It also definitely helps with manageability and keeps my hair looking healthy overall. The biggest win though is the long term results: my ends feel healthier and I don’t have to get a trim nearly as often. Giving it 4/5 stars nonetheless just because I wish it had whatever that extra oomph was the OG formula had.

Great for split ends!
[This review was collected as part of a promotion.] This product is wonderful. It really does make split ends disappear and leaves hair shiny and gorgeous. The texture is thick and slippery so be very careful not to over use. It does absorb well into the hair but leaves the fingertips feeling slick. I’m a big fan and would recommend this serum.

Hi there! Thank you for reaching out about our Nutritive Nutri-Supplement Split Ends Hair Serum. We are pleased to hear that you noticed an improvement in your split ends, as this highly concentrated serum is specifically formulated to provide instant nourishment and "seal" dry tips. While the Nutri-Supplement serum is an excellent daily touch-up for smoothing and prevention, we understand you were looking for more significant results. For hair prone to split ends, we often recommend a "complete ritual" approach: Complementary Care: Pairing the serum with our 8H Magic Night Serum can provide deeper, long-term nourishment while you sleep. Preventative Styling: Using a heat protectant like Nectar Thermique before styling can further shield your ends from the thermal damage that often leads to splitting. Your feedback is invaluable to our product development teams as we continue to innovate within the Nutritive franchise. We would love to help you find the perfect routine for your specific hair needs!

This is a great product if you are looking to supplement your ends but I think the night serum is much better for an overall supplement to your hair, not only the ends. I would buy if I am looking to keep my ends healthy.

[This review was collected as part of a promotion.] I’ve struggled with split ends for as long as I can remember. Even when I trim my hair regularly and use moisturizing conditioners, I still always seem to get them, especially in the same spots. I started using this right after my most recent trim and I’m honestly kind of shocked by the results. I have way less split ends now, especially in my usual problem areas, and I don’t feel like I need to dust my hair nearly as often. It actually feels like those sections are growing back healthier instead of breaking again right away. I also really like that it doesn’t make my hair look oily at all. If you use the right amount, it just makes your hair feel super soft and look a little shinier, not greasy. It feels lightweight but still nourishing, which is hard to find in a hair oil. The packaging itself is super nice too, the dropper is easy to use and there is a lot of oil in the product. Overall would recommend!

Lightweight but effective
[This review was collected as part of a promotion.] This serum is the bestttt. It makes my hair smell good and the scent isn’t too strong. It’s a soft nice smell. The product is very high quality and a little bit goes a long way. It definitely hydrates my hair and leaves it shiny. It’s not too thick on the hair. It’s lightweight and is perfect for my hair. I like how it also contains vitamins. It’s gonna help keep the hair healthy and hydrated. I recommend if you have colored hair like mine too.

Not special
This didn’t do much for my split ends specifically, and didn’t feel that different from an average drugstore product

We’re so sorry to hear that this product didn’t live up to your expectations, especially after you were so excited to add it to your routine. We know how disappointing it is when a product leaves your hair feeling dry and lacks the "wow" shine you were hoping for, particularly when managing the delicate balance of thin, straight hair.

Shiny hair
[This review was collected as part of a promotion.] This product feels great on my hair. It’s not greasy or heavy feeling. It provides shine and helps help my hair feeling soft. I’m not sure if the split ends and actually being reduced since I haven’t gotten a hair cut since using this to see less breakage. Overall it seems to be working great.

Healthy Shine!
[This review was collected as part of a promotion.] I really am happy I got to try this product! I’ve always been scared to use oil in my hair, however, this product has made my hair feel soft and shiny! It is perfect for split ends and you wouldn’t even think I had any! It absorbs into your hair very fast and leaves it feeling great! It does not make your hair feel oily at all! A little goes a long way! Definitely recommend!

Really works for split ends
[This review was collected as part of a promotion.] This serum is amazing! It absorbs to hair nicely without making hair feel and look greasy like other serum I have tried in the past. I have noticed my spilt ends are really going away. I only use once a week and feel it is very affective

I have been dyeing my hair for a couple years now and this mask has brought my hair back to life. And fixed my ends and it smells so good.

Light and effective
[This review was collected as part of a promotion.] I am generally very happy with this product. I'm always happy to get a dropper or pump bottle for hygiene purposes so that was an immediate plus. The bottle is a nice heavy glass, which feels high quality and expensive. The product had a similar consistency to other hair oils I've used. The difference between this and other hair oils I have used is that it really seems to soak into my hair rather than lay on top. My remaining frizz left after my blowout was mostly tamed without weighing it down. I liked the fragrance as well. I will definitely continue using this product in my hair washing routine.
I received this product in exchange for an honest review.

Kérastase Oil Serum
[This review was collected as part of a promotion.] I received this product complimentary from Influenster and Kerastase in exchange for my honest review. I’ve been using this Kérastase serum for a few weeks, and it’s made a noticeable difference in my hair. Just a few drops on damp or dry hair smooths frizz, boosts shine, and makes my hair feel healthier overall without any heaviness. A little goes a long way, and the scent is subtle and luxe. exactly what you expect from a highend product. It’s become a staple in my routine, especially on days when my hair needs that extra sleek, polished look. Definitely worth trying if you want smoother, more manageable hair day to day. It doesn't make my scalp oily but hydrated it. And my split ends aren't as noticeable. Plus I love the dropper applicator. Makes it easy to get the exact amount I need.

Unsure if it’s for me or not… need to try more
[This review was collected as part of a promotion.] I will preface this by saying that yes, I am aware I need a haircut. I was hopeful this would help the split ends a little bit, but I did not notice a drastic difference. I do want to give it more time and effort, though, which will include using varying amount of product. I also might not have left it on long enough, so I will try using it at bedtime. Next time I use it. I am not too familiar familiar with this brand so I was excited to try a couple items from the line. I definitely want to continue using this split and serum in hopes it holds me over, and will report back if things change. It feels great though on my actual hair and has a nice scent.

Must have
[This review was collected as part of a promotion.] I love this serum. My hair can get really dry but also very easily greasy from any hair products. This is light enough that it’s super moisturizing and also not heavy in your hair. I will be recommending and buying again!

Brough My Ends Back To Life
[This review was collected as part of a promotion.] Wait this is what this Kérastase hair serum smells like? I’ll be honest: I’ve truly despised most haircare brand fragrances lately, but this… this is different. It smells incredibly nostalgic.
It reminds me of warm rays of sunshine kissing my hair on a beach, fresh, and undeniably appealing quite transported. That said, the scent is quite strong, so if you’re sensitive to fragrance or prefer something subtle, I’d recommend smelling it in a salon first.
Since breaking my arm, my hair has become a split end ridden, damaged mess. What was once a simple routine turned into a daily challenge, and my hair paid the price. From one handed blow drying, to unevenly applied heat protectant, and the not so glamorous act of bracing my head against the wall just to attempt clipping my hair up all took their toll.
It shows clearly and unapologetically in the photograph, where the damage at my ends is impossible to ignore.
Looks like straw.
That being said, this product has helped drastically. The photos shown are taken one week before use and one week after, and the difference is unmistakable. My hair feels noticeably healthier, with significantly less frizz and far less breakage than before. My hair feels stronger too.
The first time I used it, the product absorbed quickly into my ends. As results became more noticeable, I found I needed less to maintain the effect, which also helped prevent any greasiness. I’ll continue using it until it’s finished and would absolutely consider repurchasing.
The packaging itself is stunning an ombré orange glass bottle that feels substantial, heavy, and undeniably luxurious. The dropper is easy to use and lets you control your amount of product with ease. I think you get a lot for the price point too.

Great for Damaged Hair
[This review was collected as part of a promotion.] Precursor: I’m only giving it 4 stars because I haven’t used it enough to see many visible results. With that in mind, so far I have like adding this to my hair care routine. I got my first perm this year, so with some extra chemicals added to my hair, it’s been nice to have a product to help with my dry hair and split ends. I love how easy it is to use just rubbing it on the ends of your hair. It smells nice, but is rather greasy on the fingers. It seems to absorb well in my hair and doesn’t leave any type of feeling on my hair afterward.

It's okay
[This review was collected as part of a promotion.] Very thin, runny serum, its hard to even suck up a full dropper because it's so thin it just drips out on its own. I can't say whether or not this actually helps with split ends but as a general finishing oil/serum it's fine.

Hello. Thank you for your feedback regarding the consistency of our serum. We are sorry to hear that the "runny" texture has made the application process a bit difficult and messy for you. We intentionally design some of our serums with a thinner, water-like consistency to ensure they can penetrate the hair fiber deeply and spread easily without leaving a heavy or greasy residue. However, we understand that this can make using the dropper a bit of a challenge. A helpful tip is to tilt the bottle slightly and depress the bulb fully before submerged to get a better draw, or to apply the product directly into your palm before working it through your ends. While you've found it to be a satisfactory finishing product, we'd love for you to continue using it to see the long-term benefits for split ends, as these results often become more apparent with cumulative use. Your feedback on the packaging and viscosity is very helpful for our design teams!

[This review was collected as part of a promotion.] The consistency of serum light weight. The scent of the product is soft and refreshing. I used this serum at night allowing the product to absorb into my hair to straighten it. The applicator is very good because it helps to get the right amount of product to apply to my hair.

Decent, but expected more.
[This review was collected as part of a promotion.] After testing this split end seum for a little less than a month, I have to admit I haven't seen much cumulative progress. It definitely gives some hydration to the ends when applied, but weighs down my fine hair so I have to be very careful with timing of the day that I use it and also the amount. I wish I had longer to test the product before writing a review because I think long term effects might lead to a different opinion. For now though, I wouldn't switch to this product over what I currently use. However, I do enjoy the scent and consistency of the product. Also, as a side note, for anyone who has sensory issues, this really coats your hands so that's something to note.

Hi there! Thank you for your honest and detailed review! We’re glad you enjoyed the scent and found the serum provided immediate hydration, though we understand the challenge of balancing that moisture with fine hair. Regarding the "weight" and the sensory experience on your hands, we appreciate those insights—they are very helpful for our product teams and other users. Since reparative results often become more visible after 6–8 weeks of use, we would love to hear your thoughts again after you've had more time to test it.
