I was excited to try this product because my scalp gets dry and itchy really quickly. I also have pretty greasy hair, so I was concerned that this serum would weigh down my hair or make it oily. The directions say to apply it once per day, either on towel-dried or dry hair. So far I've used it every day or every other day, only after showers. The serum is a little difficult to distribute with the dropper and it's tricky to completely avoid the roots. Once the serum dries it makes my roots a little crunchy, so I can't imagine applying this on dry hair. All that being said - the serum smells fantastic and I look forward to using it.

It makes my hair smell great and I haven't noticed any increase yet in my scalp's oil production. I'm excited to keep using this for longer to see if anything changes, but I would continue to use this just for the relief from my itchy scalp alone.

Ever since I started using this product, I have noticed a significant improvement in the condition of my scalp. No longer do I have to deal with those pesky dry flakes on my pillows and clothes.

My dry scalp was noticeably improved, and I felt more confident in my appearance.

To put context to my review, I have been experiencing a large amount of hair fall out and loss which has really affected the length of my hair. I started using the Scandinavian bio labs hair regrowth kit, this is something that I feel has helped to minimise the amount of hair fall out. However from using the serum I noticed my scalp becoming quite dry and flaky, also itchy which can be slightly painful due to the dryness. Having purchased this and using once I immediately felt a soothing effect, the serum is very thick almost like a gel which I love as I can feel a layer over my scalp! This has meant my scalp has been less itchy and noticed a natural boost in the healthiness of my roots. I also use the kerastase genesis range and wash my hair every 2-3 days (as ...

Having said I can’t recommend the product enough to really smooth and relieve the scalp.

I've been unfortunately struggling with a dry, itchy, flaky scalp for the past few years and nothing seems to do the trick to really provide long lasting relief. That is until I found this product and well let me say this is a game changer! Upon application I felt instant relief to my very dry sensitive scalp. It almost left a cooling sensation which felt amazing. Perhaps my favorite thing about this product however is the fact that it does not leave an oily buildup on the scalp. I was able to apply this serum daily and I usually don't wash my hair for 3 to 4 days and so I was worried that I would be left a grease ball but was pleasantly surprised when I realized that the serum absorbs into the skin nicely and was virtually undetectable even after multiple ...

The smell is wonderful, the packaging is luxurious and the product does exactly what it claims to do. If you're suffering from scalp sensitivity I would absolutely recommend this!!
It has been 7 days exactly since I've started using Kerastase Potentialiste Hair and Scalp Serum and i couldn't be happier with the results. My scalp is normally oily or dry and flaky. It gets really irritated and I've tried so many products with little to no results. Upon coming across this serum I was a little skeptical if it was going to work, let me tell you how excited I was even with my first use. Instant hydration and no oily residue. The sencond use was even better, it felt super hydrated and really did work on my 2 day of no shampooing. The smell is amazing!!! Definitely haven't found anything like this. Again easy to use gel like and hydrates immediately with NO oily residue, what else can a girl ask for... oh wait it's possible, it smells great too! ...

Definitely recommend this for anyone who struggles with any type of scalp problems. Give this serum a try before wasting money on other products. I'll be on my day 8 of this product and I couldn't be happier, specially because my scalp had been super itching and flaky lately. Haven't scratch since! You definitely won't be disappointed!!!
Living in California exposes you to a lot of sun that irritates your scalp. This item is for normal, dry, sensitive or oily scalps. A universal serum with antioxidant properties. Helps defend against the feeling of an uncomfortable dry scalp. I have been using this for almost two weeks now. You apply it to your scalp after you shower, it is a gel like consistency that smells amazing but not overpowering or alcohol like. I've noticed my scalp not itching as much and the redness of it diminished a lot, my scalp felt revitalized and refreshed. One thing that I also noticed is that my hair didn't fall as much on the second week. I would recommend this to anyone who has a sensible scalp. Not only does it help your scalp but it smells amazing I've gotten compliments on it.
Squirting the thick gelly-like product through the oversized glass tube unto my hair is a poor product design. The product ends up on my scalp and at least one inch of my hair shaft It's a messy process. At a minimum, the tip should be a soft sponge-like tip. I don't know if the product works because the application design is so poor; I only used the product 3x -sporadically, and I said I wouldn't use it again each time. It does feel cool going onto the scalp.
Let me start off by saying I am 35 and have battled with dry scalp for years, especially during the winter. I get so bad I end up scabbing. I used Kerastase Hydrating and soothing scrappy serum and for the first week I did not see much of a difference but felt my hair softer and more tamable. Once I entered the second week the itching did disappear and for the most part so did the dandruff. It left me feeling hydrated and refreshed. The smell at first was a little strong but I am also not used to heavy fragrance, however after some use I did not even notice it and it was rather nice scent. You do get a decent size bottle with purchase. The only thing I did not like is that the instructions were not in English so I had to google how to use it. But the product itself ...

My hair has been exposed to chlorine in the pool on a near daily basis from diving practice (where we don’t wear caps) and one of the biggest issues since then has occasionally been an itchy scalp and dryness. I have long, really thick, straight hair that typically gets oily quickly so finding a balance between dryness and oiliness without weighing my hair down is a struggle. About five days into using the serum (with pool use and then shower, applying it afterwards before dinner) I felt less irritation and dryness from my scalp. I’ve been using it now for about 2 weeks, with noticeable visible improvements - on weekends I am able to save my hair and avoid getting my it wet, at the expense of an oily hair comeback.

About five days into using the serum (with pool use and then shower, applying it afterwards before dinner) I felt less irritation and dryness from my scalp. I’ve been using it now for about 2 weeks, with noticeable visible improvements - on weekends I am able to save my hair and avoid getting my it wet, at the expense of an oily hair comeback. Having used the serum, there’s a lot less of the greasy feel at the roots, meaning more ‘volume’ there, and I’ve been rocking it out with my hair down because my hair is already full but the improvement at the roots completes the look. The product has balanced my scalp out and so I would highly recommend using this serum despite its high price tag especially if you have thick straight hair like mine on a scalp that’s been suffering from chemical exposure. (Also kinda want to try the sister serum Genesis with my hair breakage from the chlorine after this )
This serum is most definitely fast absorbing. It's thick, but you rub it in, and then it's fine. I've used it both on wet hair (on the weekend when I'm home) and at night before bed. Both are fine. The product says to use for three weeks. I suspect that's how much is in the bottle. When it comes to reading the directions, WOW, I had to look them up on line as they are so small on the back of the bottle and the dark shading on the bottle itself doesn't help. I ran into this problem with another Kerastase product. Other than that, I'm looking forward to my three week mark to see if it truly balances my scalp.
