Kérastase Genesis Hair Serum, Nourishing & Fortifying Leave-In Conditioner, For Weakened Hair Prone to Hair Loss, With Ginger Root & Edelweiss Flower, Sérum Anti-Chute Fortifiant, 90 ml

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.

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

This Kérastase Genesis Serum is hands-down the most luxurious way to treat thinning hair. Forget heavy, greasy scalp treatments—this is a lightweight, non-sticky gel that absorbs beautifully, giving my scalp a pleasant, cooling tingle right away. I noticed significantly less hair fall after just a few weeks of consistent use, especially when brushing and washing. The key is the powerful cocktail of Aminexil, Ginger Root, and Edelweiss Native Cells that fortify the hair fiber from the root. But let's be real: the divine scent is half the reason I look forward to applying it. It has that signature, sophisticated Kérastase fragrance—a bright, invigorating mix of woody citrus (like lime and bergamot) with a delicate hint of rose. It truly smells like you've just stepped out of a high-end salon, and the beautiful aroma lingers without being overpowering. It's pricey, but the ritual and results make it a 10/10 investment.

Expensive but smells Divine and reduces hair loss too ♥️ Have subscribed for longer use to hopefully see regrowth too !🙏

So I’ll start on the negative that my pipette came completely snapped in half! Annoyingly due to it being completely see through, I didn’t actually notice at first and just thought it had a widely insane pipette that couldn’t hold the product! So I just have half a pipette floating in the bottom. But onto the good stuff! I have almost finished the bottle and I can honestly say the smell of this product is AMAZING! I use it every night on my roots before getting into bed and even my partner has made comments on how nice my hair smells. I also am a girl who’s prone to loosing mass amounts of hair in the shower/bath and I can honestly say I’ve noticed a difference in the amount of hair I loose now! I can’t say I’ve noticed my hairs any thicker as of yet but I’m definitely loosing less of it!

Very good product my first time using it ,only used for a couple of days but am noticing a difference my hair feels stronger less breakage and less frizzy recommended

I didn't see any results. It has a very striking smell, kind of sickening

Best product i have purchased for my hair i use to shred alot especially after washing my hair now thank god not much am on my second bottle and have already stocked up on 2 more cant live without it smells amazing and does exactly what its meant to

Tengo problemas de caída de pelo por estrés desde hace bastante tiempo, y este año lo he notado especialmente en otoño; porque se ha unido la caída estacional. Uno de los productos que siempre me ha funcionado ha sido este sérum; de hecho, es la 4.ª vez que lo compro, y en este caso no ha sido una excepción; me frena la caída del pelo y lo fortalece. El cosmético se presenta en una caja de color rosa de la línea Génesis de Kerastase, con un leve precinto, e incluye información sobre los ingredientes y características del producto. Entre los ingredientes que aparecen, vemos minexil 1,5% que facilita el anclaje del pelo; raíz de jengibre, que protege de agresiones externas; y cafeína, que mejora la microcirculación del cuero cabelludo. El envase es de cristal transparente que deja ver su contenido, de leve tono rosado, con un dosificador en forma de gotero, que facilita su aplicación en el cuero cabelludo sin desperdiciar el sérum. El cosmético capilar es poco denso, con un aroma cítrico agradable. Su aplicación es sencilla; hay que aplicar 4 dosis de la pipeta del dosificador, abriendo líneas en el cuero cabelludo seco o húmedo secado con toalla, 1 vez al día, insistiendo especialmente en las zonas donde tienes más caída del pelo, y después no hay que lavarse el pelo, para dejar que el producto haga efecto. En mi caso, aunque este sérum no ensucia el pelo ni lo apelmaza, prefiero aplicármelo por la noche y dejarlo actuar hasta el día siguiente. No he notado ningún problema de picor, descamación o enrojecimiento del cuero cabelludo. Apreciando muy buenos resultados a nivel de pelo más fuerte, con más brillo y mejor aspecto y, sobre todo, con mucha menos caída. Para mí se ha convertido en un cosmético imprescindible para mi pelo dos o tres veces al año.

Un sérum parfait

O produto é maravilhoso, o serúm realmente cumpre o que promete. Porém a pipeta do produto é bem ruim, ela solta o produto mesmo sem apertar então tem que tomar cuidado na hora de passar para não cair no rosto ou no olho e vc acabar desperdiçando um produto que é caro. Só nessa questão da embalagem que acho que dava para melhorar, mas o serúm é bom, ajuda bastante na queda e no crescimento.

I have been thoroughly impressed with the keratas products. Despite my initial hesitations regarding finishing oils and serums due to my delicate bob cut, this product has exceeded all expectations. I carefully apply it after drying my hair, using the small pump to dispense the perfect amount. The formula spreads evenly and leaves no greasy residue behind. Not only does it effectively protect and tame frizz, but it also gives my hair a sleek, professional shine. It truly feels like a miracle in a bottle. While it may be a bit on the expensive side, I highly recommend making the investment. Once you witness the incredible results for yourself, you will not be disappointed. This product is simply brilliant.
