So far, so good!
I’ve been using this scalp serum for about a week now, and I’m honestly impressed so far. I started using it because I felt like my scalp was about to develop dandruff, and I wanted to get ahead of it before it became an actual issue.
One of the first things I noticed is that my scalp feels cleaner for longer. I was able to go three days without washing my hair, and I didn’t experience the usual buildup or irritation. I don’t typically struggle with heavy dandruff, but I did notice that the slight flakiness I was starting to see hasn’t progressed, which is a really good sign.
I still get some oiliness, but it feels more controlled and less excessive than before. Overall, my scalp just feels more balanced.
It’s still early, but based on this first week, I’m really happy with the results and excited to see how it performs with continued use.

I felt the differnece in my scalp upon using this and other kerataste products. I usually had dry, flaking hair even post shower. this helped a lot in my scalp health - just wish bottle was more effective in picking out the last drops. i kind of like the way the magic serum and elixir are packaged more so

Noticeable difference in scalp
I use this serum together with the balancing shampoo, and the combination has made a noticeable difference in how my scalp feels. I have thin, flat Asian hair and was often told by stylists that my scalp was tight, though I never fully understood what that meant until now. Since using the serum, my scalp feels more relaxed and balanced, and my hair has a bit more lift at the roots instead of falling flat. Overall, my scalp simply feels more comfortable.

Like the effects, but smell is overpowering
My god, what is it with Kerastase and overpowering artificial fragrances? I find this soothing for my scalp, but I try to avoid artificial fragrances because there are a lot of hidden ingredients and endocrine disruptors. I bought this with a shampoo and conditioner, and all three have equally strong smells, which are nauseating when layered together. I'll use this up but won't repurchase. Please switch to natural fragrances or fragrance free so people can just use perfume to decide what they smell like.

Thank you for your candid feedback. At Kérastase, we view our fragrances as a signature element of the "salon experience" at home, designed like fine perfumes with complex layers. However, we are truly sorry to hear that this olfactory journey was overwhelming and even nauseating for you. We understand that scent is deeply personal, and for those who prefer the subtlety of natural ingredients or a fragrance-free routine, the intensity of our layered rituals can be excessive.

Highly Recommed
[This review was collected as part of a promotion.] Purchased this as a gift for a family member and checked back in after 4 weeks of use because I was curious. I use other Kerastase products (mainly shampoo & conditioner) but didn’t have experience with their serums until now — family member highly recommends and noted their scalp feels much more balanced, healthy, and that the serum’s fragrance is amazing and lasts a long time. I’ve also smelled the serum before and can second that statement — it’s a very refreshing and clean fragrance. If I had issues with my scalp I’d definitely be trying this serum. I don’t, but this has encouraged me to look into other Kerastase products that might provide a more well rounded maintenance to my hair and scalp beyond just shampoo and conditioner. Overall, highly recommend for those with scalp discomfort…it seems to work very well!

We understand your dilemma! It's great that the product smells good, but it's frustrating not seeing results for your dry scalp and wondering if it's the product or your usage. Treating dry scalp often requires consistent application and the right technique to allow ingredients to work. Factors like frequency, how you apply it directly to the scalp, the severity of dryness, and even external influences can all impact effectiveness.

Ces produits coûtent très chers, ils promettent de réparer les cheveux et... Ils tombent. C'est tout de même étrange. Peut-être que ça fonctionne pour d'autres, mais pas pour moi. C'est bien dommage.

Mainly for dandruff I think
[This review was collected as part of a promotion.] I use rogaine, derma rolling, and laser treatments on my hair so i wanted a soothing serum for my scalp but this is more for dandruff/oil control. It's helpful and I even see a lift in my roots so I like the effects. Not the purpose I bought it for but a surprisingly good result. I use this twice a week and I dont mix it with any other scalp serums since I have sensitive scalp. It works well but it is a bit thicker then I thought. It does not weigh down my hair though. Im not sure i would repurchase but I like it so far. The next day after applying the serum to shower wash hair, my hair doesnt look any different and the hair falls flat again. Hope this helps

clean, strong and refreshing
This is a fantastic product, exactly what you need to keep your hair and scalp feeling strong and healthy. I first saw it with my hairdresser, who highly recommended it and was clearly a fan. After trying it myself, I completely understand why. From the first use, my scalp felt clean, refreshed, and protected. It absorbs quickly without leaving any residue and gives a noticeable boost to scalp comfort and hair vitality. Highly recommended if you're looking to improve scalp health and overall hair strength

Another Excellent Scalp Treatment from Kerastase!
I love this stuff!!! I am a huge fan of Kerastase scalp products! I actually got a sample of this with another order, which had enough for two uses for me. I instantly fell in love. It has a very soothing, cooking effect on my scalp. Plus it doesn’t make my hair oily at all. Just plain makes my scalp health feel on it! It’s a bit thicker than the usual hair serums, so doesn’t take much. Use with freshly washed hands/fingers a bit of oil on my ends. Hair almost down to my butt is a shiny glowing superstar🤩yet another Kerastase product to add to my fav lists :/ so many favorites I wait for sales and move it! Well worth it!

Breathe of fresh air
Finally my scalp is calm. It’s not a heavy or sticky product which is nice. It leaves you with an airy feeling. Although the fragrance is quite strong at first, it dissipates quickly. My husband loves it after a visit to the barber. Seems to sooth a fresh trim.

Relieve-prepared scalp for shampooing
[This review was collected as part of a promotion.] Your first pre-shampoo step for your scalp. I think is worthy, it does help and relieve scalp to avoid dryness and itchy.

Nice Scent, But Just Okay Results
I tried the Kérastase Potentialiste Serum and while it smelled really nice and felt pleasant to apply, I didn’t notice any major difference in my scalp or hair overall. It wasn’t bad, just not as effective as I was hoping. Probably better for someone looking for a lightweight, fragrant serum rather than targeted results.

Haven’t noticed a huge difference
[This review was collected as part of a promotion.] I use this about 3 times a week(per instruction on bottle). My scalp is less flaky. I’m going to try other scalp serums before committing to a second bottle of this. It does have a super strong smell that lasts.
