    Hair has significantly improved after 6x usage!

    Did I recommend you if you recently colored your hair. Used by my hairdresser recommendation and have no regrets. Your hair quality improves significantly after 6x usage. You would feel that u need to use less conditioner or detangle your hair. Hair also gets shinier ✨

    Worth every penny

    Do you have dry and bleached hair? Do you think this is a bit too much to pay? Let me tell you, there is no better product. A bottle of this lasts forever. REMEMBER: One pump is enough (unless you have very thick and long hair) and activate it between your hands with heat/friction until the product is white. Apply and enjoy!

    For treated hair

    For my, coarse thick hair that hasn't been treated, this feels like a basic leave-in conditioner. Of course, the hair is easy to comb through and soft/smooth after this, but if the hair is already in good condition, the product doesn't add anything extra. So the effect will definitely be more noticeable on colored and damaged hair. #lykoreview

    Amazing Product

    Visible difference after 2-3 washes. Worth the hype and money.

    Noticing a big difference. But after using it 6-7 times and starting to use conditioner again, it feels like my hair is unfortunately starting to go back. But otherwise, I've noticed big differences❤️

    Best product for damaged hair ❤️‍🔥

    Have used it diligently for several years and am just as shocked every time I use it. The only product that has helped my hair become healthy and stop falling out ❤️‍🔥 Don't forget to warm it up in your hands to "activate" it. It should turn white in your palm before you apply it to your hair 🤗

    Perfect🤩

    Works so well for many years on home-treated hair! This has been my go-to product for a few years now! Whenever my hair is in bad shape or going through it, this saves the day!

    4 minutes and then?

    Thought: when it says it should work for 4 minutes… what is expected to happen after that? What should the "working" be interrupted with? I haven't understood a wash. I don't do any heat treatment at all with my hair, but is it maybe something like that? Because it should work to just air dry the hair after this product?

      Hey Tove 😊👋 You should let the product sit for 4 minutes before you start styling your hair with, for example, a blow dryer 🥰 You shouldn't blow dry your hair after using K18, but heat (like from a blow dryer) can enhance the effect of the product 🤍 All the best!

      Hello!💗 Yes, you can use the K18 Leave-In Molecular Repair Mask after using henna. This product is designed to repair and strengthen the hair deeply, and it will not affect the coloring that henna provides!🫧 Take care!🤍

    K-18 mask

    Shouldn't you wash it out after four minutes? Since they are a hair mask, it feels weird not to wash it out haha:)

      Hey Ronja!😄 Oh, I understand that you're wondering! But you can see it more as a leave-in product instead of a hair mask. For it to do the most good for the hair, it shouldn't be rinsed out 😍 Take care!🩷
