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! 🌷

K18hair
A true lifesaver for hair K18 has become one of my favorites for giving hair a softer, stronger, and healthier feel. A fantastic product for anyone who wants to give their hair a little extra love #beautylover #k18

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 :)

Tangled Hair
Used this for the first time yesterday and followed the instructions on the packaging. But I think my hair got so tangled and feels so damaged from using it. It didn’t get nearly as soft as with conditioner and a lot of hair came out when I tried to comb through it. Why does this happen?

  Hi! 🤍 K18 is a leave-in treatment and does not replace conditioner. It doesn’t provide the same slip and softness as a regular conditioner, so hair may feel more tangled and less soft at first, especially if you usually use conditioner. The manufacturer recommends not conditioning before, but you can apply a little conditioner to the ends after the four minutes if the hair feels tangled. ✨

Saves damaged hair!
Expensive but worth the price. Saved my bleached dry hair. Use 4-5 washes in a row as a treatment. Afterwards, the mask can be used a little as needed. Incredibly satisfied with the result.

I'm in love!
After bleaching my already colored hair 😬 it became dry and frizzy and on the verge of falling off... 😅 I know, dumb idea! 😅 After googling and watching YouTube, I was inspired to buy K18. A bit too expensive hair care product for my taste, but I was in an emergency!! 😱 and yes! It really works!! I've gone through the hair treatment after 6 hair washes, and my hair is healthy!!! And the product is economical and lasts a long time for my medium-length hair! 🥰 Since the first bleaching turned orange 😿, I bleached it again after the K18 treatment 😬, and it became dry and frizzy, but K18 saved my situation again!! AGAIN! Yes, as you understand, I'm in love! But I will take it easy with bleach from now on 😅

Not worth the hype
I followed the instructions, but this didn't do anything special. It's the same as using a regular conditioner, the only difference is that this is an expensive jar. I have naturally curly, quite frizzy long hair.

Super good
Super good, has made my hair so much more resilient and doesn’t break easily. However, the hair gets a bit dry, especially the first 4-6 times #lykoreview

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?

  Hello!🤍 No, you don’t need to wash your hair again 😊 K18 should work for four minutes before you continue styling, so since almost five minutes had passed, it’s no problem that you sprayed K18 AstroLift afterwards. You can continue styling your hair as usual! All the best!🤍
