Amazing for length!
I was focused on growing my hair after a bad haircut and this did the trick! I saw great length within months and the bottle lasted around 3/4 months using it 2x a week after washing my hair! I prefer this over the Gensis growth serum - can’t recommend enough!

[This review was collected as part of a promotion.] I have been using this product after every wash and my hair has gotten visibly thicker and unlike a lot of products, this one does not make my scalp itch.

Using for 6-7 years - totally transformed my hair.
[This review was collected as part of a promotion.] The only downside of this product is that it’s increased in price over the years, but of course, I’m still gonna buy it. I couldn’t grow my hair past my shoulders for years. Out of all the products I’ve tried (some left, some kept), this is the product that’s done the most for my hair. I wish I could afford to buy all Kerastase products!

We completely understand your affection for our iconic oils, which provide that signature sublime shine, but we are concerned to hear about the buildup on your scalp. This sensation often arises when a formula is too lipid-rich for your scalp's specific ecosystem, causing the active ingredients to accumulate rather than clarify the fiber. For your fine hair, we recommend experiencing our Genesis range, which is expertly formulated to deeply cleanse and fortify the scalp while providing the lightweight strength and volume you desire. By focusing your oil ritual strictly on the mid-lengths and ends and utilizing a more clarifying Bain for your scalp, we are confident we can achieve that perfect balance of purification and luxurious care that defines the Kérastase experience.

Too much fragrance irritates scalp
I’ve been using kerastase products for a while now - I really hate how they overly scent leave in products. This made my scalp worse, irritated, and a hundred times worse. I even tried it for a few days, thinking that it was just winter making this happen. I’m so disappointed in this product. Had the same experience with the miracle overnight serum too.

I have been trying to grow my hair out for the past two years and I love this whole line because it’s meant to help preserve medium to long hair and it is divine.

Stronger hair
I’ve been using this serum for a few weeks now, and I can honestly say my hair feels stronger and healthier. It’s lightweight, absorbs quickly, and doesn’t leave any greasy residue. I love that it focuses on the scalp, not just the end, it really makes my roots feel refreshed and balanced. I’ve noticed less breakage and my hair seems to be growing a bit faster. The only downside is the price, but a little goes a long way, so I think it’s worth it for the results.

Nice texture, bad dropper
I love everything Kerastase, so this time around I decided to try this serum. While I love the texture, I'm not loving the dropper as it doesn't hold the serum inside, and when you pull it out of the container it leaks, and it's a waste of product. On the other hand, I haven't seen much results to be honest but I need to give it more time. Still, Kerastase is my number 1 go-to brand for every hair-related need.

LOVED IT
[This review was collected as part of a promotion.] I live in Florida and the climate is not the best when you have curly hair and want them straight 24/7, but the Kerastase hair and scalp serum has been a lifesaver. It smells amazing, like milk, and even after I straighten my hair I can still smell it days after. It’s helped with new baby hairs and protects the hair I already have. It makes them smoother and silk like when i blow dry and straighten them .

On the strands, it provides bit of a feeling of hydration and nourishment but I wouldn’t say that the result is anything life changing. For the cost of this product, you could get something else from this company that is much more effective. I’m not sure why they don’t improve this formula.

Love the “extentioniste line, the serum, the shampoo, conditioner & masque, all of them. I have thin blonde over processed hair and started using these products a month ago, my hair dresser suggested. In one month my hair is growing and so much healthier.

Good serum, like that it works for scalp and hair
I thought that the serum does a good job moisturizing and sealing the ends of the hair, even more than other products in the line. I would reccomend. Not as good as genesis on the scalp, but think it also does a different function.

Love this serum
I have purchased about 5 bottles of this serum already which shows how much I love it. I have natural, 4B hair and this serum helps me so much with detangling. I know it's not really advertised as being a detangler but it is great. I use it on my scalp and lengths. I typically use it on dry hair. The smell is amazing.

It works
I have used this product for several years and have proven results. I apply after I wash my hair in a concentrated area

My go-to hair serum
[This review was collected as part of a promotion.] My hair is fine, thin and blonde. Needless to say, breakage is a HUGE concern of mine. This serum works WONDERS and has made my hair grow longer and stronger than ever before!

Smells and feels great
I really like this hair and scalp serum. The smell is fantastic, like I just left the salon. It does not make my roots oily at all and I am prone to oily roots. I haven’t noticed if my hair growth has increased at all yet but it’s still new to me so hopefully with some time.

Its okay
Honestly, I really don't know if this is working or not. I have straight hair down to my chest and no scalp problems, just would like longer hair. This made my roots pretty oily and also is time consuming doing it the correct way they show in videos. I also use a lot more than 2 droppers worth.

Great serum
This serum smell divine and hoping it will help with my falling hair. I didn’t see much results yet but hoping it will. It is little oily if you add more. Perfect amount application does help.

This stuff WORKS!
[This review was collected as part of a promotion.] This product was recommended by my stylist, and I've been using it for over a year now. In that time, I obtained a new stylist, and she cannot stop commenting on how much new growth I have! We can both tell how much thicker my hair is at the scalp, and now we just wait for it to grow the full length. I'm very happy!

Great product
[This review was collected as part of a promotion.] I've been using this product forthe past 2 years. Since I used this product my hair is stronger and healthier, it is even growing longer. Easy to use, does not feel heavy or sticky. I will highly recomend it.

No results yet, but pleasant use
I'm only a month in so it's really hard to tell with these things, no obvious results yet, but it smells nice, is a nice texture and can't hurt. I'll have to report back if I see something fabulous happening, but overall I enjoy doing a scalp massage with it or throwing it on under my hat before baseball games.

Works but be patience it is not magic
As you can see, the before picture was Jan 23 and the second April 20. The growing is there, I have been using the whole extensionise line since December, but the serum only since the beginning of February. I like it so far my hair is healthy and I can see the grow. I don't give or 5 stars because the serum price is too high for 50ml, it is the same price for the genesis serum which is 90 ml.

Poor bottle choice
The glass tip you use to pull out the liquid is awful. The product is way to liquid that it just falls out, dripping everywhere..i was trying my best to be careful not to waste any..but recently a drop fell right in my eye. So im annoyed enough to come write a review. I also dont have sensative skin but i do feel some irritation. I wanted so bad for this to be all the hype, im only 1/3 in so i cant say if the product actually works yet.
