    not recommended

    Unfortunately, after several months of use, the effect on the hair is zero. Instead, it gets greasy, and the hair needs to be washed again the next day. Such a shame because I had high hopes for the shampoo and had heard many positive reviews before.

    Does the series suit me?

    I have normal thin thick hair, it's kind of Scandinavian and I bleach it maybe 2-3 times a year but it easily gets frizzy and dry at the ends and oily lightly? Not really super thick hair and I lose a bit when I shampoo sometimes and have medium wavy hair, not really a lot of volume.

      Hey Klara! 🌞👋 Of course I can help you with that! Kérastase Resistance Bain Extentioniste is a great choice to strengthen your lengths, especially if they become dry and frizzy after bleaching. 💫

    Which one suits me?

    Hi! I have long blonde hair that is quite straight, a bit damaged, has some split ends, and is pretty frizzy. It has medium porosity and gets oily quickly but is dry in the lengths. It is neither thin nor thick. I aim to achieve long, strong, thick, and shiny hair without frizz that grows fast. I've been considering this line and the Genesis line but I'm unsure what is best for my hair, what do you think at Lyko?

    Genesis or extensioniste

    Hi! I have fine curly hair, I'm 53 years old, so it falls out now and then, and the hair is not the same at this age + I have highlights. Which shampoo is best?

      Hello 😊👋 The Résistance line is specially formulated to repair damaged hair and helps strengthen the hair fiber from root to tip. The Genisis line, on the other hand, focuses on weakened hair with tendencies to hair loss 🤍 Based on your description of your hair, it sounds like the Genesis line would suit you best 🥰 You can also try our free hair test, where our experienced hairdressers can recommend products that are tailored just for you! 🙌😍 You can go directly to the test via the link: lyko.com/sv/beauty-scan2 All the best!

    Resistance shampoos

    What is the difference between this shampoo (Bain Extentioniste) from the Resistance line and the Bain Force shampoo? I have damaged hair, especially my lengths and ends, but my scalp gets oily quickly. Which one should I buy?

      Hi Kirsten🤍 Great question! The Kerastase Resistance consists of 3 different lines. Force Architecte = for weakened and damaged hair. Therapiste = for severely damaged and weakened hair. Extensioniste = prevents hair breakage and split ends in long hair. 🤍 The Resistance line from Kerastase is definitely suitable for your hair type. If you have long hair, I recommend the Kerastase Resistance Extensioniste to prevent further damage. I also always recommend using a suitable conditioner and a scalp mask or hair oil to properly hydrate the hair and allow it to grow back healthy. ✨

    My holy grail

    I've been using this together with the conditioner for several years almost non-stop. Sometimes I also use their hair mask and sometimes I switch it up with other hair masks (Birch Moisture Hair Mask is a favorite!! Smells magical and leaves the hair so soft) 💫 I've tried to test something else in between because I'm curious, but I can't tear myself away from this line, it smells so incredibly good and has helped my hair, which has several old bleaches at the ends, to still grow long (from stopping just below the shoulders to reaching down to the hips). It smells luxurious and lasts for several days after washing. It's also quite economical, so I don't feel like I need to buy it often, making the price very reasonable for what you get + that it lasts so long. 🌟
