I was LITERALLY one salon visit away from chopping it all off!!! Knots the size of Rhode Island, tangles, dry frizzy flyaways that were sucking hours outta my day and ridiculous amounts of money outta my wallet! ONE use and I was getting a comb through my hair and my locks looked HEALTHY!!! <insert audible gasp> My ONLY complaint is that with long, thick hair, a "pea-sized" amount is NEVER gonna work for me! Y'all need to add a refinancing application onto your "checkout" page for us sing...

My hair is curly but when it dries it is frizzy. I have spent a small fortune trying to find a product so I could wash and let dry without styling. This product is amazing! I usually dry with big barrel dryer but I don’t have to. I would recommend this product to every one. I would like to try the serum but I can’t find where to order it.

The leave-in mask has been a lifesaver for my hair! I’ve gone through multiple rounds of bleaching in order to get a silver/light brown hair color and the mask has made my hair noticeably softer. I can’t wait to stock up again. Definitely worth it.

Enjoying the masque on my limp hair. I filled out a survey from k18 last week that said I got a free gift. Was that real? I did it but online you never know. Thanks, Debra Manning

I have fine bleach and dyed hair. After my shampoo and putting this in my hair, I could not believe how easy it was to comb through my hair! My hair used to have frizzy areas, but not anymore.

This product is absolutely the most amazing thing I have ever put in my hair. My hair was extremely damaged/over processed and I have thick, long and naturally curly hair. I used this K18 leave in hair mask once and my hair was noticeably different! I used it after a couple more washes and I am so impressed. My hair is softer and smoother and feta goes easily. It is expensive, but I plan to use it sparingly. Ultimately, I’m hoping my hair cuticles recover even more while I let my hair gr...

I have tried most every so called miracle product out there and then some looking for the solution to my keratined, color treated hair that was looking pretty dull and lifeless. Up to this point all of them were a bust, but on a whim I tried K18, with modest expectations. Boy was I (pleasantly) shocked when my hair became silky, shiny and youthful looking after just the first use! And it’s only gotten better and better with each time! I never want to be without it again! So very, very pleased! A...

First I want to say that I was skeptical, to say the least. I ordered the trial size first and was able to use it 3 times on my little longer than shoulder-length hair (3" longer than shoulder). I did see immediate results in the texture and the way my hair looked. For a long time now I have struggled with what I think is dry hair. I have tried so many great conditioners both wash out and leave in and was never able to achieve smooth hair, especially in the 3-4 inches of my hair. I could get i...

I have very thick course hair so the first time I used this product I did not use enough my hair was snarely so the next time it was perfect I used a little more so I must say it made my course hair feel good

Amazing results the first time I used it! My hair was over processed, over colored and heat damaged and it showed. I was going to cut it all off but K18 has given life back to what was dry, brittle and dead. Thank you K18 😊💓☺

I have bleached damaged, wavy, high porosity hair. After the very 1st use of this my hair felt softer and I could comb through it with ease. Great product! Can't wait to see what happens with more use.

I am on my 2nd bottle of this miracle in a bottle. I have curly hair that has been bleached (over color) in order to blend my gray grow out. I use Olaplex, which is good but my hair was still so fragile & brittle, and would break easily. Adding this to my routine has been a game changer. My hair is actually soft now and I can curl it and blow it straight with no breakage and it is smooth. I no longer have to wear my hair naturally curly every day and frizz is minimal. In case you are wondering, ...

I've been a hair dresser for 15 years, and I have NEVER used a product that made my hair feel this good! I just went from dark brown to light blonde recently, and used another brand to make sure my hair stayed healthy. I didn't feel like it did what it promised. So I tried your product and was amazed! My hair feels heathy again, even after all the bleach and damage!

I tried this product for the 1st time as I did the process of bleaching out my hair and toned. After the process my hair became very dry. I used your product Leave-In Molecular Repair Hair Mask and could not believe the difference it made in my hair. Thank you! Great Product. A.Briceno

I have very fine hair that (because of aging) had became dry and frizzy. I could not do anything with it. I tried K18 and it feels wonderful. The dryness was gone the first time I used K18 and has continue to improve. This product is amazing. I would recommend it to anyone, especially the 50 and over group. It is well worth the money. My hair feels like it did when I was younger. I love this product.

Before using this conditioner I was having an extended bad hair day. Every day I would look in the mirror and was unhappy with how bad my hair looked. My hair is thin, damaged and aging and nothing was helping it to look better until I decided to try a sample of K18. Using this leave-in conditioner makes my very fine hair look healthy. Huge difference ladies! Also, I find that it doesn't weigh my hair down and gives it volume which is a game changer for me. The instructions say that you don't ne...

My Hair went from dry and damages to soft and easy to manage! I had tried every product I could find or was recommended by hair dressers and NOTHING worked. Thank you

So glad I found this! It really does work best after using a clarifying shampoo and no conditioner and I have already noticed an improvement after using a few times. As I've gotten more gray, my formerly super straight hair is now wavy and gets frizzy easily. I've been using heat to smooth it down but high heat plus coloring had it looking pretty bad. Between K18 leave-in and turning down the heat on my dryer and iron, I'm optimistic that my hair will look a lot smoother soon!

Using this product has made my hair more manageable. I’ve done the first series of 4 and now ready for the second series. Experimenting with the quantity needed and finding it doesn’t take much to make my hair silky.

This product was AMAZING. Unlike Olaplex it actually seems to detangle and moisturize, and let me tell you, it's been years since I could get a fine tooth comb through all my hair. I was exceedingly pleased and in spite of the very high price point, will probably buy again.

What the F***!!!! This product was a complete game changer for me!!!! It’s what I hoped Olaplex would’ve felt like. My hair is very damaged and I’m in the process of growing out a modern shag mullet...BECAUSE of this product and this product ONLY I will not be chopping inches off of my hair...I’m going to order another sample size because I’m unable to purchase the full size at the moment. But I CAN’T wait to order it.

Amazing! Just one treatment and it made my over processed hair softer and more manageable. Completely got rid of my frizz. I wish it was in my budget to buy the full size.

I've just used the trial to date but also compared it to another leading brand. It requires less product and seems to combine a repair and frizz treatment. At least for my hair, which as I move through my 50s is dryer. I color but do not do much else so there isn't horrible damage. As I grey out I am coloring roots monthly at home. Over the past year a lot was not tended to, so the K18 will be working overtime for a bit.

Absolutely exceeded my expectations. K-18 does everything it says it will. As a hairdresser I wanted to use it on myself before being used on my clients to really get to know the product and it is amazing!

I was able to squeeze two uses out of the single use trial tube and noticed a difference right away. I'm so pleased with the product that I immediately ordered the larger size to begin using regularly.

Have noticed a difference after just a few uses of this product. My hair feels stronger and has much more shine. Looking forward to even more improvements over time. Thank you for such a great product!

I have quite thick volume of hair but the strands are fine. Many leave-in conditioners cause my hair to look greasy but not this one! It also didn’t take out my natural curl. Grateful for the trial size before making the bigger investment.

My hair gets better every time I use it. This stuff is my hairs holy grail. So smooth and frizz free. I use twice a week. Keeps my hair on point. Will definitely be ordering my third bottle soon. Thank you!

Amazing results and gets better after every application. My stylist had been adding highlights for the last year to lighten and blend my graying roots but with fine, thin hair, it has been very damaging. I was skeptical about buying another product that supposedly repairs hair. K18 Biomimetic Hairscience is the real deal. Thank you!

Ordered this product after my hairdresser recommended it! I’ve just ordered my 3rd & 4th sample size! It truly changed the way my mids to ends look! I’ve been bleaching my hair for years & even though I use the whole Olaplex line, I’ve gotten the best results from this product! I cannot stop touching my hair!

My hair was feeling damaged and felt like it had lost its elasticity after I had it bleached to blend with my newly grey roots. I had watched a video about this product and, although, it was costly I decided to go for it and I am so glad I did. After only one treatment my hair felt and looked so much healthier. I would highly recommend this treatment and would also highly recommend following the exact directions on how to use it.

K18 is almost unbelievable! My hair was in very bad shape due to thyroid disease and I was sure I would need to cut it all off. However, I have been following Jack Martin, a wonderful SoCal colorist on FB and he highly recommends K18 for his color clients with hair in bad condition. So I decided to give it a try. I cannot express my sincere appreciation for this remarkable, effective, wonderful product and I cannot recommend it highly enough after just 4 uses. For anyone who might think it's a ...

Before investing in the full size product, I decided to try the sample size first. I have natural curly hair, that is more coarse and dry, as I’ve transitioned to my natural gray. So far, I am very pleased with the increased suppleness and conditioning K18 has provided. I have used twice now, and have enough for a third test. Overall, I am pleased with the product, just not sure if it’s worth the price tag for the full size bottle.

I started bleaching my hair to put silver streaks in it. There was alot of breakage the first time. I started using K18 after my first touch up and I can see that there has been no new breakage and the original breakage is growing out. It's so easy to use and my hair feels AMAZING,

I can hardly believe how the frizz left. After not getting a trim due to shutdown, I ordered this stuff. I did what it said and was still not believing anything would really happen. Here I am months later giving a review because stuff did happen! The good stuff happened! I could let my hair air dry or I could use a dryer and product and my hair never looked worse-for-the-wear. This stuff is incredible. For the first time, I am a believer.

I have fine hair with layers that I wash and flat iron everyday, which was taking a toll. My ends were looking frazzled.& damaged. K18 is a lifesaver for my hair! It’s smooth again! I’m in love with this product! P.S.The picture was taken after the first use. It’s gotten better since then!

I love this stuff! I can really tell a difference. I have fine frizzy hair. I have been using it every wash (I wash my hair every 3-5 days) for the last 3 weeks and my hair is smooth and super healthy looking. I am so glad I found this product!

I only bought the $12 sample to try and I was very happy with the results. Barely enough for 2 applications so needed to use a little longer to get true results but was pleased the 2 times I used the product.

This product is life-changing. I wanted to transition to gray and it took its toll on my hair. I tried so many things to bring it back to my original, shinny hair. The only thing that worked was K18. I’ve never had such dramatic, immediate results ever! I would recommend it 1,000% to anyone.
