    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! 🌷

    Economical and effective
    The product is easy to apply to the hair and does not leave a greasy feeling afterward, which I like. I have used the product for about 7 months and my hair is in better condition, and it’s not advisable to use the product all the time. The scent of the product is also good.

    Repairing
    Have been using this product for over a year now and notice a huge difference in hair quality! I previously fully bleached my hair, which made it dry and damaged in every possible way. After incorporating the product into my routine (along with other products, of course), there is a huge difference in both the moisture in the hair, the shine, and overall quality. The product is easy to apply and smells good. The only downside is that if I apply the product after showering, the hair feels a bit greasy. BUT it’s not noticeable if used during the shower routine! I will definitely continue to buy this product.

    It's so good
    I have oily scalp and dry hair. It suits my hair so well I don't even have to even use anything like a conditioner or hair mask after i use it.

    Huge disappointment - zero results.
    I waited a very long time for a discount so I could buy this talked-about mask. Luckily, I got it with 40% off, otherwise I would have been extremely sad. I have long, somewhat dry hair with highlights. Typical damage from bleaching. I've used this mask three times now on towel-dried hair without using conditioner. Each time I used more and more product (first 2, then 3, then 4 - no help!) and NOTHING. Very difficult to detangle hair (I waited a few minutes as instructed). I also regret the time lost detangling my hair - if I had used conditioner, mornings would go faster. ZERO results. Luckily, I didn't expect any shine, because there was none. The hair did NOT become stronger or better in any way.

    Absolutely incredible
    I am in the process of going from black box dye with several years of buildup, and it really wouldn't have been possible without this product. My hair is still here & I am now blonde, the length is intact & the hair feels good🥹

    100% worth the money!
    This totally saved my bleached and heat-damaged hair! However, you should be careful not to overuse it, otherwise you can get too much protein in the lengths :)
