    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.

    Expensive

    I have really tried. Detox/clean shampoo and then massage into damp hair and leave it on. I don't experience any miracles, which I expect given the very high price. The hair feels softer but the ends and roots feel the same as before. Unfortunately, I don't feel it's worth the price. I had high hopes for this.

    Combine products

    I have oily (but dry) scalp and dry, frizzy lengths. I was thinking of buying K18 Detox Shampoo and the mask. Can I use the mask on the lengths and a different serum on the scalp, like Ida Warg Cure Scalp Serum or Löwengrip Anti Dandruff Treat & Care Sensitive Dry Scalp Serum?

      Hey ASOW! 👋🏼😊 It sounds like you have a bit of different needs for your scalp and lengths, which is completely normal. K18 Detox Shampoo and the mask are a great choice for cleansing and strengthening the hair, but since your lengths are dry and frizzy, I would recommend adding extra moisture. This hair mask is really amazing 🤗lyko.com/sv/waterclouds/waterclouds-smooth-hairmask-250ml You can definitely treat your scalp with a serum like Ida Warg Cure Scalp Serum or Löwengrip Anti Dandruff Treat & Care Sensitive Dry Scalp Serum 🥰 Have a really nice day! ☀️

    Styling Products

    Can you use your regular styling products after the 4 minutes? Or will it be too much product then? I usually use Ref fiber mousse at the roots and Lanza Healing Strength Silk Serum on the ends.

      Hey! 🌿 Yes, it works absolutely great to use your regular styling products after the K18 Leave-In Mask has worked for the 4 minutes. The mask builds up the hair's bonds but leaves no "heavy" film, so it doesn't get too much product. Take care!🤍🫧

    LOVE!!!

    I've probably bought K18 4 times. My hair is naturally light brown, thin hair strands, but many hair strands so my hair is quite thick. I've started doing blonde balayage in the last 2 years, and chose to buy this pricey item at the beginning of my hair journey. Before bleaching, I use K18 about 4-5 times before I dye my hair, and then after freshly dyed hair, I also use it about 4-5 times. My hairdresser has been amazed at how good my hair feels, I do love intensive care so I use a ton of different products and take care of my hair, but I notice a very big difference with just K18! If you have the chance and have been tempted to try it, go for it! It's really soooooo good🤩 #lykomisson

    Conditioner?

    Do you have to stop using conditioner and other treatments before using this?

      Hi Izabella 😀 The recommendation is to shampoo the hair and rinse, do not use conditioner or hair mask. Then towel dry the hair. Apply K18 and let it sit for 4 minutes. Do not rinse out. Style the hair as desired 🤍 For best results, it is recommended to use the following 4-6 washes and then every 3rd to every 6th wash as needed 🥰 Wishing you a nice day ❄

      Hey MarieAK! 👋🏼😊 One pump is about 1ml, k18 is a very concentrated product 🤍 For best results, it is recommended to use the following 4-6 hair cleansers and then every 3rd to every 6th wash as needed 🤗 Have a nice day 💫

    Like this, nice visible results if you have light bleached/blonde hair! Too bad it's so expensive. I would probably buy it more often if so

    K18 Leave-In Molecular Repair Mask – My hair wouldn’t have survived without this. Honest review

    I have been using K18 regularly since 2021, and it literally saved my hair when I went from dark brown to blonde. The process involved 3 bleachings and 3 rounds of highlights in under 1 year – something that usually leaves strong marks on the hair. My hairdresser commented several times on how strong my hair still was, despite the treatments. What I notice most with K18: • Hair feels stronger from within • Less breakage • More elasticity • Smooth surface • Long-lasting shine The best part is that it doesn’t just give a temporary soft feeling – it builds up the structure over time. I use it especially after chemical treatments and every 4th wash. Today, several years later, my hair is still smooth, soft, and shiny – even after a major color transformation. For me, this is not just a hype, but a staple product that will always be in my routine. Highly recommended for bleached or chemically treated hair that needs real repair. #konkurranseinflutester
