    Hair has significantly improved after 6x usage!

    Did I recommend you if you recently colored your hair. Used by my hairdresser recommendation and have no regrets. Your hair quality improves significantly after 6x usage. You would feel that u need to use less conditioner or detangle your hair. Hair also gets shinier ✨

    Best!!

    The best hair product out there, it has saved my hair many times during bleaching and now it’s always a part of my hair care routine. Minus for the expensive price but it’s worth it!! And it’s long-lasting so it still lasts a while for me using it 1 time/week.

    Use together with Nioxin?

    Can K18 leave-in be used together with Nioxin shampoo and conditioner?

      When you use K18, wash with only Nioxin shampoo, skip the conditioner, and apply K18 to towel-dried hair. For other washes without K18, you can use Nioxin shampoo and conditioner as usual! 😊🙌

    Saved my damaged hair from bleaching

    This product saved my double bleached hair a year ago. I did not like how my first colouring turned out and went in for second time which was a HUGE mistake (I have naturally dark brown hair). I wish hairdresser have told me. My hair was gummy, split ends were coming out of nowhere even though I tried to trim them everyday and hair was just breaking…. I tried hair masks and then I stumbled on this. At first I did not notice anything, my hair was super dry when I used it without conditioner. I later figured out you could still put on another leave in conditioner to soften hair. But after couple if month, things started to change. My hair would be so soft and lively after using this product. I grew out the damaged hair and now use it as prevention (I heatstyle). ➕great with damaged hair, especially bleached (but probably what is bleached beyond hope would not be saved) ➕smells great (better than one from living proof) ➕definitely better than Olaplex and easier in use ➖price (so expensive and so tiny bottle🫠)

    Rough hair?

    Hey! My hair gets rough and not smooth when I've used this and it's dried completely. Is it supposed to be like this? Why?

      Hey Evelina Linnéa! 👋🏻 It might be that your hair needs a bit more moisture 💧 You can add this in two ways - with conditioner or leave-in! Conditioner: After K18 has worked for 4 minutes, hop back in the shower and apply the conditioner, which you then rinse out. So it’s totally fine to rinse out K18 when it’s done working 👌🏻 Leave-in: After K18 has worked for 4 minutes, apply a leave-in cream or spray that moisturizes the hair. This one from Waterclouds is a favorite 🤩 lyko.com/sv/waterclouds/waterclouds-repair-deep-shine-cream-150m Hope this could be helpful! Wishing you a super nice day ☃️

    Mixed opinions!

    I have been using this hair product correctly for 4 months now and I'm halfway satisfied. I can feel that my hair gets softer the day after use, and it smells good. The reason I don't give it full marks is that the product should deliver better results for the price. I use other products that give better results for cheaper money. :)

    Question: New formula or?

    I've bought this a few times before, but this time it's different. Previously, the product turned white and a bit sticky when I rubbed it in my palm, but now it's more like a gel or serum. Has the formula changed or is there something wrong with mine? I thought it was good before, but not anymore in this consistency.

      The last time I bought it, it also had a different consistency than before, I don't know if something is wrong or if it has a new formula?

    Usage

    If you use other products like protein cream for hair, should you use the protein cream before or after K18's leave-in product?

    Good product

    This is definitely a good and very nourishing/reparative product, but really expensive, and since I have very thin but dry hair, it made it look a bit heavy and dirty. I don't know if I should only use it on the ends, which is a shame since my lengths are so dry too. #LYKOREVIEW

    Is my hair ruined??

    Just used K18 for the first time. My hair felt so ruined afterwards, I had to go back in the shower and wash it again. It didn’t help, it’s so so porous, looks like it’s gone from everywhere, so dry and frizzy. What happened?? I’m so defeated! Doing my second hair journey after losing half my hair after pregnancy. Just managed to grow a bit out again plus got better quality after almost 1 year. But now, no, I feel completely ruined 😢

      But this is what I was afraid of and thought, when denatured alcohol is listed as the first ingredient. This is the most drying alcohol found in hair products, why add it to such a hair product??
