    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 ✨

    K18

    I have previously bleached my hair many times at home, also highlights at the salon. My hair has had good quality despite that until last autumn. After a long period, I have let it be. Suddenly, my hair starts to break off, especially in the front. It grows but breaks off a lot even though I take care of it. My hairdressers have recommended this product. Can this help me get my long hair back and stop my hair from breaking off as soon as it grows?

    Incredible!!

    Absolutely fantastic product. I have dyed, bleached, and damaged my hair for many years. Then I lost ENORMOUS amounts of hair last year due to stress and weight loss, my hair broke off on my head and had extremely many split ends. 2(!) uses of this and my hair both feels and looks so healthy. Love it! Too bad it's so damn expensive but it’s probably worth it.

    Disappointed

    This product disappointed me. I have heard so much good about it and was recommended it at the hairdresser. It is a quite expensive product, so I expected it to be worth the money. I have long, thin, and somewhat damaged hair. I use heat treatment maybe 10 times a year but rarely cut my hair. I felt my hair got softer when I had the product in it, but otherwise nothing? I did everything right, washed my hair several times before applying this. Did not use conditioner. Rubbed it in, and applied it in my hair. Used it once a week. Now the product is empty and I have really noticed 0 difference. My hair just feels dry and awful. It tangles and gets greasy quickly. I think this is a product that works for people who style their hair with heat products and have damaged hair in another way. Unfortunately, it didn't work for me. The product smelled good and I liked that you don't have to wash it out. It is a product that is easy to use in a busy everyday life. #konkurranseinflutester

    Soft hair

    My hair became soft when I used it, but I don't see any difference in the hair otherwise. Too expensive

    Usage

    Hi! I just started using k18 and have done it according to the instructions, so shampooed and then applied k18 and no mask/conditioner. I've done this 4 washes now and next time it will be a "normal" shower for the hair with mask and conditioner. But now to the question😅 when should I use it next? And shouldn't I use conditioner/mask then either? Should I wait 4 minutes with that and then apply my remaining products?

      Hey Jennie! 🥰 You’ve done everything right so far by using it as a treatment with every wash for the first four times, that’s exactly how K18 recommends starting 👏 Now that you’ve done the first four treatments, you can switch to using K18 about every third to fifth wash or when your hair feels like it needs a little extra love 💙 When you use K18 again now 👇 Wash your hair with shampoo, preferably deep cleansing if you have a lot of product in your hair. Skip conditioner and mask. Towel dry your hair and apply K18 and wait for 4 minutes! So you should always use K18 alone after shampoo when you finally use it, otherwise it can’t repair the hair deeply 🙌 Take care!! 🤍

    Hey!

    I just ordered this and can't quite make sense of all the instructions. I understand that you're not supposed to use conditioner beforehand, but does the hair mask work? Or hair mask and conditioner after application and wait at least 4 minutes? I have newly bleached, very dry and damaged curly hair, and just the thought of not using conditioner or hair mask makes it hard for me to understand how to detangle my dry hair 😅 I'm currently using the Redken Extreme line with shampoo, mask, and conditioner but also have the Redken ABC line for curls and always double shampoo when washing my hair.

      Hey Lisa! 👋🏼 I understand, let me clarify this! This should be used after shampooing, so no mask or conditioner first. This is so that the hair is as 'open and clean' as possible so K18 can penetrate 🫧 After 4 minutes, I find my hair to be very soft, but you can absolutely go in with a mask or conditioner here if needed. This will not ruin the effect of K18 👌🏼 Hope you feel wiser and will love K18 as much as I do! Take care 🌞

    Lifeguard!

    It was between K18 and basically shaving off my hair (or cutting it super short). Now, 4 washes later, my hair doesn't even need a haircut. K18 is what has been considered impossible - it REPAIRS HAIR. I tried it once before, a smaller tube and thought it didn't do much then, but that was because my hair wasn't damaged enough. Now it was like limp gum. But no more! I will never want to be without ♡

    Wow

    So, I tried it ONCE, first time today, and I just stood there gaping in front of the mirror. I have damaged bleached hair. Thin hair strands but many. My hair feels as fresh as it felt when it was really healthy. Before this product, my hair was like straw. So my mother-in-law recommended this, and I got it from her. So after one use, my hair looks fresh and newly cut, and it feels healthy when I touch it. It felt like a weight and bounce in my hair at the same time, and so smooth and nice!! Looks like I’ve been to the hairdresser and cut off all the damaged hair!!! Can’t wait to use it for a long time and see long-term results 😍😍😍

    Thick and dry hair

    Hi! I have very thick brown hair that is also dry. I don’t bleach it, but it still feels like it’s very damaged since the ends stick out in all directions. Is this product something that can help or a waste of money? Best, Olivia

      Hey Olivia! This product is not just for colored hair but also for someone who has damaged hair from, for example, heat tools and other stresses that hair often has to endure! 🥰👌 So caring and strengthening for the waves simply🤩 Hope you like it!
