Clear difference – but no miracle cure
A serum that soothes the scalp without weighing the hair down. The gel-like consistency absorbs quickly, without leaving a greasy feel, and makes the hair feel light and fresh. I have a combination of an oily, yet simultaneously dry and itchy scalp, and thought this serum would be perfect for restoring balance. ☀️ My scalp doesn't "flake" as much anymore, and I find that it doesn't itch as quickly after I've washed my hair. However, it hasn't eliminated the itching, but I still notice that it gradually makes a difference. 🌧️ I have a love-hate relationship with the scent. Initially, it smells fresh and clean, but after a few days, it tends to smell more like "cleaning product" and quite strong, which I unfortunately do not appreciate. 💡 I prefer to apply the serum before I go to bed so that it has time to soak in properly; alternatively, I sometimes apply it before I blow-dry my hair – which has worked really well. I find it easiest to use the dropper to apply the serum to the scalp so that it doesn't just end up on the hair strands, and then massage the product in with my hands until it starts to dry. Overall, I am positive about the serum, but I wouldn't say it's a miracle cure that completely restores balance in the scalp. I am participating in a test panel and received a free test product. - Most helpful negativeThe post was made 3 monthsRating: 2 out of 5
No difference
I have had recurring problems with an itchy scalp for many years. Therefore, I need to use specific shampoo that helps me in the long run, and when I saw that there is serum from such a good brand as Kerastase that is supposed to help balance the scalp, I got super excited to try it! The serum came in a really nice packaging and smells divine! But unfortunately, I experienced no other benefits... It says that you should use the serum once a day for 3 weeks, and today I finished the course, but unfortunately, I notice absolutely no difference. I first thought that I could skip my specific shampoo and see if just the serum would solve my itchy scalp, but after using it for two weeks straight and there was no change, I had to start using the shampoo again. The consistency is pleasant, and I have used exactly 3 doses every day (as it said on the packaging), but I felt that the 3 doses were not enough for the whole head (only the front then). I would have liked to use more, but then I am afraid it wouldn't have been sufficient. One plus, however, is that the hair does not get oily from it, regardless of whether you use it on towel-dried hair or on dry hair. My final answer is that if this serum existed just for the scent and didn't cost as much, I would want to buy it over and over again, but otherwise, it unfortunately won't be a purchase any time... I had the opportunity to test this serum on behalf of Smartson and got it completely free.436 views- The user's roll: Customer service at Lyko. The comment was made 3 monthsHi Christina!

This is good!
I have been lucky enough to test four different products from Kerastase, and I like this one. My scalp was catastrophic since I swim several days a week and dye my hair. With this serum, my scalp has improved. It smells good, and the bottle is nice. However, you have to be careful not to drop it in the sink, because then it might break. Like the other products I have tested, the price for this one is also too high.

Ok
The review was conducted on behalf of Smartson - the test pilot tried the product for free. This serum from Kérastase is a good choice for a scalp that feels unbalanced or irritated. The consistency is light and absorbs quickly without weighing the hair down. After use, the scalp feels fresher and more soothed. The serum contains, among other things, prebiotics and vitamin C, which help protect the scalp's microbiome and strengthen its natural barrier. It is easy to apply with the dropper and does not need to be rinsed out. The scent is mild and luxurious, giving a salon feel at home. The price is on the higher end, but the product can be a good investment for those looking for a healthier and more balanced scalp.18 views - The post was made 1 dayRating: 4 out of 5
Delicious but not for me
I have had the opportunity to test this delicious serum from Kerastase in collaboration with Smartson. I have used it for 4 weeks, but I don't think I have had such a visible effect from it… maybe because I didn't need it from the start. This serum smells lovely and doesn't leave the hair sticky or greasy. I think that after a bleaching or coloring, where the scalp can be irritated, it is really nice.26 views - The post was made 2 daysRating: 3 out of 5
Gentle for sensitive scalp
I often have a scalp that gets out of balance, especially when I train a lot, sweat, or wear a hat. I tested the Kerastase serum for four weeks and notice that my scalp feels calmer than usual. I don't get as many small “pimples” as I usually do when my hair is trapped or after dry shampoo. The bottle feels luxurious and the applicator is quite okay, easy to use. The scent is pleasant and my hair doesn't get greasy, which makes the serum a good complement to my regular hair care routine.

Pretty okay
I found the product difficult to use because my hair became so damp that I either had to wait several hours or blow-dry my hair. However, when I finally did, I thought the product kept my hair fresh for more days than usual.

Delicious but expensive for the price
“The review was conducted on behalf of Smartson - the test pilot tried the product for free.” I have been so lucky to test this delicious serum! I think it delivers on its promise to soothe the scalp. It is easy to apply and work into the hair. It doesn't make the hair greasy, which I think is a huge plus when it comes to serums. However, I think the price is a bit high for the product, and the product gets used up quickly.17 views - The post was made 3 daysRating: 3 out of 5
Luxurious Test Assignment
I have been able to try four of Kerastase's hair serums for four weeks; *Kérastase Nutri-Supplement Scalp Serum *Kérastase Serum Anti-Chute Fortifiant *Kérastase Serum Potentialiste *Kérastase 8H Magic Night Serum I have never used serum before but am grateful to have had the chance to try. Kérastase Serum Potentialiste is the serum that I felt the least effect from in the test. I applied it early in the evening, 3 doses. This was the hardest serum to apply, it was sticky and slow-flowing, and I felt like I got more in my hair than on my scalp, even though it might have just felt that way. I also thought it was difficult to make three doses last for the entire scalp. However, it smelled very good! Since I tried so many products at once, it's hard to know which did what.

Lovely feeling and pure experience
I have tested this after showering, and then blow-dried it. I feel that it feels good and luxurious. I don't have any direct issues beforehand with my scalp, so I don't really know how unbalanced feels, but it is a luxurious step in the hair care routine. It smells good and feels good.

Drops that make a difference
Serum Potentialiste gave an immediate feeling of balancing the scalp. Just like Nutri-Supplement, I found it somewhat sticky initially, and I had to blow-dry my hair to get rid of the damp feeling in the scalp before I went to work. But after blow-drying, the hair didn't look greasy, but rather fuller and healthier. What I really appreciate is how the scalp feels calmer and more harmonious. I haven't had irritation, itching, or tightness during the testing period. It feels like the serum strengthens the very "foundation" for hair growth. In combination with the other products, I noticed a clear improvement in both hair quality and hair loss. The hair feels stronger at the roots and more vibrant. This is a serum that may not provide an immediate wow effect in the lengths, but works more long-term on the health of the scalp – and it shows over time.10 views - The post was made 4 daysRating: 4 out of 5
Serum Potentialiste
I tested the Serum Potentialiste in collaboration with Smartson, and I have been really happy with it. It is easy to distribute in the scalp and gives a fresh, clean feeling without weighing the hair down. After a few weeks of use, I actually noticed that I wasn't shedding as much as before, which was a big positive surprise. My scalp feels more balanced, and my hair generally looks healthier and stronger.29 views
