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! 🌷

K18
Ok, unfortunately I apparently have a short memory... I washed my hair and applied a tiny bit of K18 molecular leave-in hair mask... sprayed some K18 astrolift before 5 minutes passed. Do I have to wash my hair again now?

Dry
Dry product, so a little goes a long way and since I don’t use it more than once a week except in the beginning when I used this every wash the first 5 washes as recommended. I don’t feel a big difference but still think it does something. It feels like my hair strands have become a bit stronger but I also don’t know 100% if this product specifically contributed to that. Many hype this up to the skies and I think it requires a lot of time and continuous use to see bigger results if you don’t have incredibly, incredibly damaged and bleached hair. However, the technology and ingredients seem promising so based on that they should have done something. I’ve used it for 9 months so I will continue to use it and see if I notice a bigger difference so I’ll get back!! I use it as Abbey Young recommends since my lengths need lots of moisture so you let it work for 4 minutes after deep cleansing shampoo and then put in conditioner and rinse out. I think this method works better as I feel I get more moisturized hair this way while also getting the repairing properties from K18. As it is now, I’m really torn about whether I would buy it again or not because for that money you should see and feel more difference but on the other hand it lasts a long time and I have seen some improvement. #k18 #k18mask #repair #abbeyyung #abbeyyungmetod #hair

Saved my hair!!
K18 – a real investment for your hair ❣️ The first product I truly treated myself to in the slightly more expensive category was K18, and wow – what a difference. This is a product I have become so incredibly fond of and that I will definitely continue to treat both myself and my hair with going forward. K18 Leave-In Molecular Repair Hair Mask is an intensely repairing treatment that helps restore the hair’s strength, elasticity, and quality. What makes this product so unique is K18PEPTIDE™, a patented peptide technology that works on the hair’s structure and helps repair damage. The result for me is softer, stronger, and significantly healthier hair that feels almost like new. I have medium-length Scandinavian hair with very fine strands, and despite the length, I actually only need about 1-2 pumps per treatment. I use it about twice a week and have really noticed a big improvement in my hair’s quality since I started using it. I use it as a step after my shower routine and leave it in the hair without rinsing out. That’s also what’s so convenient – you don’t need to use much product to get a noticeable effect! ✨ Is it expensive? Absolutely. And you don’t get a huge amount of product for the money. But for me, it’s one of those products where I feel it’s worth every penny. My hair feels healthier, stronger, softer, and easier to manage, and it’s a difference I can really both feel and see. K18 has simply become an essential part of my hair routine – and a product I no longer want to be without❣️

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.
