    saves everything❤️

    My little sister's hair has just been bleached at home, then washed and treated with the K18 mask. Her hair shines and is elastic, and there is no bad feeling from the bleaching. This formula repeats every time I dye her hair. It works on my own hair too, and I just ordered a bigger size for the first time.

    Save your money and don’t buy

    Bought this product because of all the GOOD reviews, if I had been smart I would have gone by the bad ones and never bought it (but naive as one is, you ignore the bad reviews when the positive ones are more). I am naturally blonde with Scandinavian hair strands. I bleach highlights occasionally to lighten a bit. Have followed the instructions to the letter for a few months now with no positive result. My hair becomes STAW after EVERY use so I don’t understand using this WITHOUT conditioner/hair mask??!! Every time I apply the product, I get a lot of hair strands in my hand afterwards, never happened with any product before. I have heard comments for a few weeks now, and just TODAY from colleagues who asked if I had gotten a haircut when I haven’t even done that (I myself have noticed that my hair has gotten shorter since using this "completely perfect rescue for hair" product). Talk about total devaluation and throwing money away. I haven’t changed anything else in my product routine, nor my diet or anything, so I am 100% sure it’s time to throw this crap in the trash.

      Hi Linn! 😊 Thank you for your review and for taking the time to share your experiences with the product, even though it wasn’t quite right for your hair! 🤍 The K18 Leave In Molecular Repair Mask is designed to strengthen damaged hair, while bleached, less damaged Scandinavian hair sometimes needs more focus on hydration and softening care. A strengthening treatment can feel different depending on the hair’s needs and the balance between protein/strength and moisture 🙌 If your hair feels dry or rough after use, a more moisturizing line might suit you better. If you’d like tips on alternatives, we’re happy to help — we’re just an email or a call away 📧📞 Wishing you a really nice day! 🌷

    Washing

    I wash my hair every other or every third day approximately and will start with this for the next 6 washes. My hairdresser said it’s perfect to use k18 detox shampoo beforehand. My question is, can I use the detox shampoo every time I wash it now or how do I do it?

      Hello Evelina! 👋 So exciting that you are going to try this 😍 Detox shampoo is recommended to be used 1 day a week or as needed. Therefore, it might suit you to use it about every third wash 🩷 Hope you like the products!

    Leaving Olaplex for K18 (Leave In Molecular Repair Mask)

    I have tested this product for 2 months and to my great joy (and surprise), my hair is now noticeably stronger and somewhat fuller. It no longer breaks off and it feels fantastic! An expensive lifesaver in need.

    No wow

    Not sure if I've used it for too short a time, but I really don't feel the WOW with this, have heard sooo much about it everywhere but really don't experience the kind of miracles others have Will continue using what I have and see if I change my mind 👱🏼‍♀️

    Yes!!

    I bleached my hair at the salon a few months ago and had problems with my hair feeling so sticky when washed. A friend/former hairdresser recommended trying this K18 Leave-in mask, so I wanted to give it a chance. I followed the instructions carefully and my hair felt completely different after just one use!! It doesn’t feel sticky anymore! Looking forward to using this more going forward. (I also work in a workshop and my hair is exposed to a lot of chemicals, so I hope this helps a bit with the chemical exposure too) The price doesn’t matter when a product fixes the hair this well.

    Good product

    I think it’s a very good product, took my hair from impossible to manage to finally getting it under control. But I’m still a bit unsure about how to use it the right way. After shampoo and without conditioner or after shampoo and then apply conditioner? The first four times I used it, I only left it in my hair for four minutes after shampooing, and then applied conditioner and it worked well, but then it suddenly worked better without the conditioner. A bit unsure about the method – does anyone have tips/experiences on the best way to use the product? 😊👱🏼‍♀️
