Game changer for hair health
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!

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!

This Extentioniste is amazing for long hair, to keep the hair healthy while growing and recovering from straightening/blow dry and day-to-day damage. I had cancer and lost my hair, so while it grows, I’ve been using the Bondi Boost HG shampoo and this one and the fine hair Masquintense (Nutritive) - twice a month. This one specifically is super hard to find in Australia, so thank you Amazon!

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 !
