My magic bullet
My starting point: - long-term commitment to Kerastase - I guess that’s why I’ve seen no ads and basically stumbled upon this serum during regular eyeballing of Kerastase catalogue. So I didn’t get any hype - I’m 31F with slightly highlighted fine blond hair and reactive scalp, that is healthy in remission and flaky/oily during flare-ups - after losing a lot of weight and a terrible long flu with 2 courses of antibiotics, I went into telogenic phase. I had my hands full of hair after every wash and actually had to unblock the drain. My scalp was itchy and flaky, my lengths were damaged and electrostatic, roots wouldn’t keep volume for more than a day - I tried everything: minoxidil, castor oil, scalp massage with a silicon brush, peelings, masks - you name it. It did slow the hair loss, but I still struggled Found this serum, and it’s day 10 of the course. Serum: - smell intensity: 8/10; some might find it very intense and I get it. For me it smells of an expensive aftershave and it doesn’t bother me much since I enjoy unisex perfume - texture: 10/10; thick serum that is very easy to measure and apply. You have enough time to distribute it before it goes dry, and the best part is that it actually doesn’t leave any residue and can even add a bit of volume. During first application I felt tingling for a short period - likely due to irritated scalp. Staring with second day, no more tingling - value for money: 10/10, but it’s tricky. If you apply it per instructions, one bottle will last about 2 weeks. That’s 1/3 of required 6 weeks, so you can easily multiply the cost by 3. At the same time, this serum turned out to be super efficient for me, and it very well justifies the cost. I’ve spent more time and money, trying other treatments - ease of application: 8/10. Instructions are clear, the applicator is sturdy and intuitive. It’s easy to measure and apply directly onto the scalp. You may need to adjust the quantity since the instruction says 3-4 doses (which is a lot) and if you are smart you can get it down to 2.5-3. Efficiency: I don’t usually review products halfway, but I’m so impressed with this serum already, so I couldn’t wait to share it. I notice no to very little hair fall. It’s even less than I normally have. Almost no hairfall during washing. My scalp went calm after the very first application and no more itching or flaking ever since. My hair holds volume. So overall I’m super impressed and this serum is exactly what I needed given my background

Hair goals 100
Great product! This hair serum smells amazing, feels lightweight, and has definitely reduced my hair fall. My hair feels stronger, smoother, and healthier without being greasy. Really impressed with the results and will definitely be purchasing again even though its pricey it lasts along time.

Helped with hair loss but not with hair growth!
I’ve been using the Kerastase Serum for a while now, and overall I think it’s a great product for reducing hair shedding. I noticed that I’m definitely not shedding as much as I used to, which was my main concern, so in that sense it really helped. I’ve gone through about five bottles so far, so I gave it a fair chance. However, when it comes to new baby hairs, hair growth, or increasing the density of my hair, I personally didn’t see much of a difference. So for controlling shedding, I would recommend it 👍, but if you’re expecting noticeable regrowth or thicker hair, it might not deliver those results.

Worth the money spend (Slight costly)
Started to see effect after 2 weeks of usage, some people like the smell but some might not. it is good. Slight costly but ingredients are high quality so the price.

Did not work for me
Oh, how I wanted to love this product! I did everything right - patiently used 2 bottles, applied the right amount religiously and waited to see the results, as per so many positive comments. Unfortunately, there were none. Absolutely nothing has changed. I would also add that if you follow the instructions and use 4 pipettes (up to the line) on daily basis, it is impossible for the bottle to last as long as promoted. With all that, I am sadly resuming my search for ‘The’ hair growth serum.

Sérum muy recomendable para fortalecer cuero cabelludo.Aplico con el pelo húmedo, después de su correcto lavado y secado para retirar exceso de agua, y deja un acabado fresco sin engrasar con buenas sensaciones. Huele genial y su precio es razonable para una marca con prestigio en sus productos.

Es ist wirklich gut! Finde den Geruch sehr angenehm und ich habe sichtbar kräftigeres und volleres Haar / Wimpern. Brennt leider sehr in den Augen. Trotzdem 5/5!

With the use of this product and one other my edges are regrowing!
