I am my worst enemy when it comes to my hair. I love to experiment with the realization I might just end up with extremely short hair. I do love all the fun colors as well, but the stripping of color out of my hair leaves me with straw on my head. BUT NO MORE! I decided to start going lighter and after the double processing and toning once again I had a disaster but after 3 applications of K18 my hair was SAVED! I cannot believe how manageable and shiny my hair is after treatments with K18. Thank you K18! As a professional esthetician and nail tech, not to mention a sales rep for several professional brands, I have tried so many products, not to mention sacrificed my hair for many hair shows! K18 is a great home use product! Cheers to exploring a rainbow of colors!

K18 leave in repair mask is a very good conditioning treatment, it left my hair feeling much better, smooth and healthy. I have thick dark brown hair and while I don’t color my hair I do have some heat damage. I also really appreciate that it comes with a pump instead of in a container making it very clean and easy to use. I will continue using it as directed on the bottle and I hope to see a noticeable difference within a few weeks. I’m an esthetician so I’m not we’ll versed in hair care and can’t say much about the science behind the product just that it left my hair feeling good and that I’m excited to continue using it, I’ve always tried to keep my hair as healthy as possible, let’s see what k18 can do for my hair in a couple of weeks.

K18 BIOMIMETIC HAIRSCIENCE Leave-In Molecular Repair Hair Mask is not like any other product on the market. As a hairstylist with over 11 years of experience, I have never seen or heard of a product that repairs hair from the inside out. It doesn’t coat the hair that has been damaged, it works on building back the bonds naturally that we break, when we have hair damage. K18 goes travels to the polypeptide chains to reconnect the chains that break over time in the hair. This isn’t the same as bond builders that you see on the market, it doesn’t just protect the hair from the outside. It builds the bonds back up from the inside out using science that heals the broken bonds over time naturally. I used this on my overly processed hair and saw amazing results. I started using it as directed which is shampoo your hair, rinse, then towel dry your hair. I used one pump on my entire head of damp hair. I applied it from the midshaft to the ends and then applied any other remainder of the product to the roots. This process cuts out other products as you don’t need to add any other conditioner to your hair. I waited 4 minutes before I styled my hair as I had a noticeable difference in the bounce and feel of my hair. As directed, I used it every time I washed my hair for the first 5 washes. I saw the healing occurring as my ends were softer, my breakage was actually growing back faster than before. After the first few washes, I then used it as a preventative mask once a week. My hair has never looked or felt better. I am highly impressed with the results as this was science and the anatomy of hair structure mixed together, to heal and repair the hair without coating it. I highly recommend the K18 Leave-In Molecular Repair Hair Mask to anyone suffering from damaged, fragile hair, looking to repair and heal their hair.

This product is great for damaged, dry, and frizzy hair. I was extremely shocked when I used it for the first time. It left my hair super soft and glossy. I highly recommend this product over glossing or keratin treatments done at salons costing so much more. A little bit goes a long way, the packaging is clean and beautiful. The formula is not heavy or oily at all. It's extremely hydrating and lightweight. The scent on this product is nice but not harsh. Great for individuals that are allergic to fragrances. It's travel friendly because of the unbreakable packaging and size. If there is one hair product you would like to try in 2022, this is it. K18 will give you the hair you've always seen on models and thought if their hair was real or not because of how healthy and shiny it was.

First of all, I just have to say where was this when I was bleaching my hair???!! I was BLOWN away by k18. I have tried what seems like every hair mask, bond repair out there and nothing compared to this. In terms of how much product I actually needed to use vs how much better my hair has been feeling l, I am impressed. I admit it was scary and counter intuitive to not condition in the shower. After towel drying and working the mask in (and waiting the 4 minutes) I was able to brush through my hair no problem. My ends are a bit split from heat damage and I definitely have some areas that get really tangled. I've used it about 3 times and I have noticed a significant improvement in some of the really hard to brush through areas. Overall my hair still felt light and bouncy which after a leave in treatment is surprising. I have shoulder length hair which is fine, but I do have a lot of it. I used a pump and a half and that was plenty. If you are looking for something to help with the integrity of your hair even if it is not chemically treated I would definitely recommend k18.

I’ve been seeing the K18 Leave-in molecular repair mask everywhere! To my surprise I was able to sample it through beauty tap! Let’s get Into it! I love hair masks I try them often. I’m a licensed esthetician but I’d like to consider myself a hair mask connoisseur. My hair is not color treated but does run on the dry side. The K18 mask has a very pleasant scent. The bottle is small and easy to use. I always love products that have a pump… but the pump on this hair mask didn’t work for me. This K18 mask retails for $75, to be completely honest I don’t think i would buy this product. For the price point I would hope for a bigger size product. I wanted to love this product and tried it several times. I didn’t really see such a visible difference in my hair. I followed the instructions since it is a different type of hair mask. I was hoping this product woild show more of a transformation for my hair but it did not.

Here there Everyone! It's your beauty addict Timeki! Today I am here to explain to you my experience with K18Peptide hair treatment. This is a wonderful vegan and cruelty free hair mask. These polypeptide chains seep in to fill in the missing gaps to rebuild any broken or weak areas. I played with dry and damp hair for extra protection. After shampooing, you must towel dry and use no conditioner. At first glance, I expected the hair mask to be sticky or tacky, but it wasn’t at all. When using it on damp hair, I used the mask to rod my pony tail and tested how long the curls lasted. Caution: follow the directions when applying to your hair, if you add too much product, you will have to wash it out. When rodding the dry hair, I only used enough product to cover the hair evenly. This breakthrough product is a must have in your collection!

K18 is one of a kind incredible, works like no other product on the market. In just 4 minutes K18 with its patented peptide technology will repair your hair from bleach, coloring and all chemical services. Your hair will be strong and smooth and bouncy and best of all shiny. It actually reconnects the broken peptide chains, It is so simple to use. I have been in the beauty industry for over 30 years and there has never been anything like this before even though some products have claimed to do what k18 can do, If you have ever wanted to really trey something that will actually work try K18 and get on the new hair bandwagon. There is only good things about it and I'm going to use it forever and ever !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

As beauty enthusiast, while I enjoy getting professional help on my hair, I also enjoy doing my hair by myself and home. Styling it myself, cutting and coloring. I have a wavy color treated hair. Colored it too much that took its toll and is very damaged. Thankfully, I was given the chance to test this hair mask and in a week of using this daily, my hair is becoming smooth and bouncy again. Split ends are slowly diminishing and it is less tangled easy to comb with less breakage. The scent is amazingly fresh and not overwhelming. While I enjoy any hair care products I still have to be very careful due to my skin sensitivity. And this product definitely works for me. I can't wait to see for my hair to be back to its 100% health with overtime use of this mask.

This review is for my type 4 sisters. I have 4b/4c hair and only blow dry and straighten my hair at most a couple times a year and I don’t color my hair. I don’t have chemical damage, probably more mechanical and environmental damage than anything, but K18 says this product will still improve the integrity of hair that has never or rarely been chemically processed. That being said, after using the leave-in once my hair was very soft, however I didn’t really see any visible difference to my hair. But as stated earlier, I don’t have extensive hair damage. The reason I gave this product 4 stars is because not being able to deep condition my hair is really disruptive to my wash day routine. I have fine hair that tangles easily, so after using a clarifying shampoo I pretty much need to deep condition to be able to soften, detangle and add moisture back to my hair. I know you can add a leave in after leaving K18 in for a sufficient amount of time, but that’s not quite the same. So I do feel I had a bit more work to detangle my hair and because I didn’t deep condition, my wash day results weren’t quite the same. However, if you are someone with extensive hair damage, this might only be a small inconvenience for a product that would repair your damage.

Working with cosmetics for over twenty years, each year brings a new batch of products that are beautifully packaged and have equally enticing promises to smooth, hydrating, de-wrinkle and in the case of hair care undo the damage we inevitable do to ourselves. I am no exception I love a good highlight and my Revlon Styler and Volumizer gets VERY hot. K18 was an immediate must for me to try. I was intrigued by the minimalist packaging and science-heavy marketing materials. The brand asserts they took a radical path of biotech to develop K18 Hair. On using, the first radical moment I had was not conditioning in the shower. I used the Ouai Detox Shampoo when I tried K18. I did a pump and a half for my long fine hair(the packaging allowed for the half pump with a light touch) I was able to brush through pretty easily despite skipping a detangler and after styling, I found my hair was smooth and shinier than what I am accustomed to with no compromise on volume which can happen with other leave-in products for me. I have used K18 an additional three times and I am continually pleased with the results!

I’m an esthetician and while my specialty lies within skincare, I do know a GREAT hair product when I discover one. When it comes to hair I’ve always been super low maintenance and don’t really color my hair often nor use a ton of heat. I also don’t shampoo/ condition every day (only 1-2 times a week). I’ve also never used shampoo with sulfates. I’m lucky because my texture is super smooth and doesn’t get out of control nor tangled when it dries naturally after being wet. However, over the years my hair has been getting drier and more dull. This product literally revived it and gave it life. It was the missing link to my lifeless hair. The peptide nanotechnology in this product is powerful, effective, and results-driven. I was a bit skeptical because it threw some shade at Olaplex (which is also amazing but now I definitely stand corrected and see why). My hair is slightly color treated and is on the drier side. I was getting kind of helpless because even with conditioner it felt really dry and lifeless. Overall, this product worked wonders on my hair. It is literal magic in a bottle. 4 minutes and you have new baby/ virgin hair again. I am super inspired and excited when it comes to washing my hair and styling because of this product. My hair feels so much healthier and the texture is noticeably smoother and changed. Even when I only rough dry my hair it looks like I’ve had a professional blow out.
