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! 🌷

This is exactly the product that really raised my doubts, because the price scared me and I thought it wouldn’t do any magic to my hair. However, it happened that I fell in love with this product and it has done exactly what it was supposed to!👏🏻 My hair is somewhere between very rough and smooth, and with this product I have managed to tame it, and now the hair sits nicely. The usage experience is not difficult - I washed my hair normally, skipped the conditioner, and applied this to towel-dried hair. Now I have used it twice and I’m looking forward to seeing what this does to my hair in the long run.

The Savior for Bleached Hair
This became my savior after bleaching my hair at the salon twice. The first two times I used the product, I was skeptical, but after the fourth time, I noticed a big difference in the quality of my hair. Now it no longer breaks off and feels much stronger.

Try different ways to apply
I've used this on and off for a few years and bought several bottles, applied it in different ways, etc. I think the product is great but it's good to know that it doesn't compensate for an otherwise bad routine. However, in combination with a good shampoo and conditioner, it's top notch. Like many others, I don't love the original way of applying (shampoo, not conditioner). I felt the wow effect when I started applying conditioner after K18. My current application method is: shampoo, rinse out, wring out as much water as possible, K18 for four minutes, then conditioner and then rinse everything out. I have such thin hair that leaving it in doesn't work well; no matter how little I take, it gets sticky. Still, I notice a big difference using it and that the result gets better over time. If I had more patience, I would also towel dry before applying, but honestly, I usually don't. If you have hair like mine – Nordic, thin strands, length between shoulder and bra strap, etc. – my recommendation is to buy the smallest tubes to start with. That will be enough for the first treatment, and then you can decide if it's worth buying bigger ones.

K18 Leave In Molecular Repair Mask 50 ml – strengthening leave-in for damaged hair
K18 Leave In Molecular Repair Mask 50 ml is an intensive leave-in treatment for hair damaged by bleaching, coloring, chemical treatments, or heat tools. The formula is designed to strengthen the hair, improve elasticity, and make the lengths softer and more manageable. After shampooing, conditioner should be skipped. Towel-dry the hair and apply K18 Leave In Molecular Repair Mask one pump at a time, evenly from the lengths out to the ends. Let the treatment work for four minutes without rinsing before using other styling products. The creamy consistency spreads easily, and a small amount goes a long way. The benefits are that the treatment works quickly, does not need to be rinsed out, suits various types of hair damage, and can help hair feel stronger, softer, and less frizzy. It is important not to overdose, as too much product can make hair heavy or stiff. The price is also relatively high. K18 Leave In Molecular Repair Mask is best suited for bleached, chemically treated, or heat-damaged hair that needs a concentrated strengthening treatment.

A new favorite
⭐️⭐️⭐️⭐️⭐️ K18 has truly become a staple in my hair routine! 💛 I use it once a week after Schwarzkopf BlondMe Repair Brightening Shampoo and skip conditioner, just as the instructions say. After towel-drying my hair, I apply about 3 pumps, distribute evenly through the lengths, and let it work for at least 4 minutes before gently brushing through my hair. I am currently on a hair journey and trying to minimize all damage. Therefore, I also let my hair air dry after each treatment. My hair feels softer, stronger, and significantly less frizzy after use. I look forward to continuing to use it and seeing how the results develop over time. A true favorite that I will keep buying! ✨

Question
Hi! I've seen on TikTok that you should rub the product between your hands to work it up so that there is much "more" shampoo in the hair. Is this recommended by K18? It works, and I feel like the product lasts much longer when you do this! Thanks!

  Hi Elin! 👋🏼😊 K18 doesn’t need to be used that way 🤍 It’s designed to be applied in a thin and even layer, and it’s enough to spread it in your palms and massage it directly into your hair so it’s evenly distributed through the lengths. Rubbing it into your hands to create a “foam” isn’t necessary; the important thing is to get an even application in the hair ✨ Take care 😍

Has saved my hair!
I, who straighten my hair every day and quickly get split ends, have really been saved by this. I do a treatment when I notice the ends starting to split, and then it comes together right away and saves me another month until I need to go to the hairdresser. I have very thin hair strands and I think this is significantly better for me than, for example, Olaplex, as this does not become as dry and straw-like in the hair.

Notice a difference
A good product from K18 that has made my hair softer and easier to manage. Started using leave-in 4 times after each shampoo, and then used it every 4th hair wash. Nice to use when the hair needs a little extra care. Very economical in use😊 #lykoreview #k18 #lyko

K18 Leave in
Really good & repairing, but don't use it too often as it can dry out your hair. I usually use it about once a month and notice such a big difference 🤩
