I absolutely love the Kérastase Resistance Masque Extentioniste!
This hair mask has worked wonders on my hair, making it feel stronger, softer, and healthier. After using it regularly, I noticed a significant reduction in breakage, and my hair feels much more manageable. The mask deeply nourishes the hair, leaving it shiny without weighing it down. It’s perfect for anyone with damaged or slow-growing hair, as it helps to boost strength and promote longer, healthier locks. Highly recommend if you’re looking for a high-quality, effective treatment!

Value for money
Little goes a long way to keep my hair strong even with a perm. But greatest brand for decent price and lasts long time.

Después de varias semanas usándolo, puedo decir que esta mascarilla es una salvación para cabellos debilitados o maltratados. La textura es cremosa y se desliza muy bien en el cabello húmedo. Yo la dejo actuar unos 5 a 10 minutos y el cambio es inmediato: suavidad, brillo y menos quiebre al peinar. El aroma es delicioso sin ser empalagoso y se mantiene sutil en el cabello. Desde que la incorporé a mi rutina con el shampoo de la misma línea, noto que mi cabello crece con más fuerza y se ve más saludable. Definitivamente es un producto de alta gama, y aunque el precio es más elevado que otros, el resultado lo vale. ¡Repetiré sin dudarlo!

silky hair YES PLEASE
This product leaves my hair feeling soft and silky. I used this product when I was dying my hair (copper) it really made a difference. My hair did not seem that dry after using it despite the constant coloring sessions. I no longer color my hair but if I were to this is a product I would definitely be using on a weekly basis.

Great as long as used correctly
I use this product on wet hair after a wash and before final rinse - I do tend to use a little bit and only the ends of my hair otherwise my hair will be very oily . I have tried to use it as a mask on all my hair etc but dosent work for my hair

Great hair mask
Loved the product smell and texture of my hair after treatment. Pricey yes, but for processed hair, worth the investment

Not sure what’s up with the bad reviews...
This seems to me to be the product that it claims to be. It is the same consistency, fragrance, and achieves the same results as I to which I am accustomed. My hair is 2’ long, fine, and dense. This definitely makes it appear more vibrant, extremely glossy, reduces frizziness, and seems to have reduced the prevalence and rate of damage as I continue to let it grow — much like the representative of a religious sect who solicits by knocking the doors of single family homes in random neighborhoods to pass along pamphlets predicting the nearing of end times — thanks to COVID. No complaints, plan to repurchase.

Best conditioner for dry hair
I had some issues with my hair growing slower than normal and it got dried out. This conditioning masque literally brought it back to life. I left it in for about 5 minutes when I showered and that did the trick. Highly recommend.

Been using this for years for weekly hair masks. I wash my hair, apply to damp hair, and sleep in it overnight. Hair is so healthy and shiny now!

it’s the best hair mask I’ve ever used always used cheap ones thinking they didn’t the job untill I got too impatient with how dead my hair was and didn’t want to just wait it out so I decided to start using growth and repair hair lines!!!and this was definitely the best, after just 3 used my hair was so soft every day even without using it and it helped my dead and split ends it’s like they were never there, u don’t need to use loads either and it’s so light weight and smells lovely not too strong like perfumes !!

J’utilise le masque Extensioniste depuis plusieurs semaines et les résultats sont vraiment au rendez-vous. La texture est onctueuse, facile à appliquer, et l’odeur est juste incroyable comme toujours avec Kérastase. Dès les premières utilisations, mes longueurs ont semblé plus fortes et moins cassantes. Mes cheveux sont beaucoup plus doux, plus brillants et surtout, ils se démêlent sans effort. Après un mois d’utilisation régulière, j’ai même remarqué une vraie amélioration sur la pousse : mes longueurs paraissent plus saines et mes pointes moins abîmées. J’apprécie aussi qu’une petite quantité suffise, le pot dure longtemps. C’est devenu un indispensable dans ma routine capillaire. Je le recommande vraiment à celles et ceux qui veulent renforcer leurs cheveux longs fragilisés et gagner en longueur sans sacrifier la qualité !
