Lovely serum for hair growth/anti fall
I’ve been using this serum consistently for several weeks and have been really pleased with the results. The lightweight formula absorbs quickly into my scalp without leaving my hair feeling greasy or weighed down, which makes it easy to use every day. I’ve noticed my hair feels stronger and healthier, with less breakage when brushing and styling. While it hasn’t transformed my hair overnight, with regular use it has helped improve the overall condition and made it feel more resilient. It also has a fresh floral scent. Although it’s more expensive than some alternatives, I think it’s worth the investment if you’re looking to strengthen your hair and reduce breakage over time. I’d happily repurchase it. Also you don’t have to use 4 pipettes as directed. It depends on how thick your hair is and how damp your scalp feels so just see what works for you. I use two a time

Worth every penny
I’m experiencing postpartum hair loss, and after finishing the 30 ml bottle I noticed around a 50% reduction in hair shedding. My hair feels stronger, and I see far fewer hairs coming out when I wash or brush it. The serum is lightweight, doesn’t make my scalp greasy, and is easy to apply. A little goes a long way. I’ve been so impressed with the results that I’ve just ordered the 90 ml bottle. It’s expensive, but for me it’s been worth every penny. Highly recommend if you’re struggling with excessive hair fall.

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

Worth the money
Love this product! I noticed less hair loss when brushing my hair and I’ve felt my hair become softer and stronger. It also has a nice smell to it. I put it on my roots. It has lasted me a while.

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.

Works quickly
I was reluctant to buy something so pricey not knowing if it would work or not, but I’m really pleased that I did. After only a few days I started to notice a difference. Less hair loss in the shower after having used conditioner- hopefully the subsequent improvement in the look of my hair will continue.

Worth the money
Deffo would recommend as it smells so fresh and for me it lasted a bit less cuz I have already thick hear but it breaks easily so it helped with that and it is not greasy at all and I love the quality.

Muy buenos resultados, aroma agradable y no ensucia el pelo
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.
