I’m 52 with wavy, processed hair. I also have a naturally frizzy texture in my crown area. I noticed a difference in how my hair felt and behaved after the 3rd application. Now after 6 applications I will always have this on hand. It made each strand of hair feel thicker & more smooth. After sleeping with a pony tail before the ends would look like a tornado hit when I woke up. Now the pony tail is messy but smooth when I wake up. My stylist was impressed by how my hair felt too and we joke abou...

I love how smooth my hair feels after I us this product. I just started.. so I've been putting it on after every wash. I will have to wait and see what it's like when I don't put it on as often anymore.

I have dark brown hair that my hair stylist lightens to white. Instead of feeling like straw, K18 makes it soft and silky. Recommend this product to everyone with bleached hair!!!

my hair was dry, breaking, just looking all around frazzled and unhealthy. I friend told me about the product and I have been very happy with the results. Even my hairdresser said there was a noticeable difference after just a couple of weeks using K18. can't wait to go back the next time to see if there's even more improvement. it appears there is from what I see in the mirror but nice to have a professional confirm. thank you for the great product and excellent customer service!

K18 is amazing!! My relaxed hair was breaking and thin on the ends. I had been using Olaplex which helped but too many different steps. K18 made THE difference after the 1st use! I'm sold on it and will be buying more

This product is amazing . It really relaxes my hair, it is not as frizzy as it was after my hair color. I would recommend this product to any individual who bleached or dye their hair a lot.

I Love, Love, Love this product! I even ordered the larger pump size of K-18. My hair is absolutely as soft as it has ever been! I'm a believer!

My hair was extremely damaged from years of coloring, bleaching and lots of heat styling. I was hoping for a miracle for my hair based on what I saw on so many IG posts. After the first use, I didn't notice a difference. After the second time, still nothing noticeable. But after the third time using K18, I saw and felt a major difference in my hair!! My hair is definitely not breaking like it used to when I brush it and it feels and looks so much smoother than before. My son likes to play with ...

This has been a wonderful experience. I am a very senior citizen with fine thin hair. Since using your product I have gained body and shine for healthier happier hair. I'm not even using hair spray to hold my hair in place. Wash, blow and go!!! Had my hair cut today and the salon owner ask what I had been doing to my hair. Hopefully she will start offering K18 to her clients. Many thanks for your product.

My hair stylist raved about this product. She used it after my haircut. I bought the sample size to try at home and it’s fabulous - just be careful not to use too much. It really makes your hair silky and smooth and no build up. I use it a few times then switch back and forth with my regular conditioner.

I’m 57 with home colored light blonde hair that is naturally all white/gray. My hair is thick but fine textured, curly, hard to dry and style and very sensitive to humidity. I ordered the K18 at home leave-in product after seeing Jack Martin rave about the salon products on Instagram. It’s amazing stuff... I’ve used it for four consecutive shampoos over 12 days and my hair is smoother, softer, easier to manage and more resistant to humidity. I’m about to order more so I don’t run out! Don’t...

I had little faith that this product would do anything for my crazy, aging hair, which I was set to cut off, but I was dead wrong. I ordered a trial size, but after one use I ordered again. I was truly shocked at what a difference this peptide formula made in the overall quality of my hair (and I have tried it all). I feel like 20 years has been knocked off hair that had become unruly and frizzy in age. So satisfied.

I just started using it and with the first time I noticed such a huge difference in the way my hair looks! I hope it continues to improve and get the healthy hair I so desperately want

I had stopped putting color on my hair and let it go natural salt and pepper. I have natural curly haid and it tends to frizz. I have used the product 2x now and love the way it makes my hair feel. I WILL be a returning customer. I even took it to my salon today and used it instead of her product. Told her to look into the product.

I had my hair silver highlighted to help with my grey transition and I had some small sections of my hair that did not fare well. They were breaking and were rough and crispy. After about 4 uses, those areas have completely been repaired! At first I was disappointed as I was expecting results with the first use. But I was patient and kept at it. I highly recommend this product.

I was skeptical when I saw the amount and size of the sample I bought to try out the product. I have long hair and I didn’t think there was enough to do my hair even once. I have now used it for two shampoos and I might squeeze out a third application. More importantly, I have noticed a big difference in my hair. It is softer, smoother and holds the style for days. I am growing out my gray after decades of dyeing my hair and I am so pleased with the quality of this product.

I have gone on a "blonde journey" this last year, as I used die my hair dark dark brown for over 10 years! In attempt to keep my hair healthy between heavy bleaching sessions, I stumbled across K18. I read all the science on their website and was very intrigued. The first time I used it, I fell in love. I have been using K18 since and I even raved about it so much my salon started purchasing the in-salon treatments! My friends constantly ask how I have kept my hair so healthy despite transitioni...

It is quite a rarity for me to give an outstanding review on a haur product. My hair took a real beating this past year with me attempting to cut, color and style at home. Truth be told, my hair was at the cotton candy stage and nothing would work to bring it back. So, I saw this product promising the impossible. What do you know? It works. I will keep using it, and highly recommend it. Try it at least. Work it into your strands, you won't be sorry.

I admit I was skeptical at first, because I have purchased so many products that have promised great results, including keratin treatments which ultimately result in my hair getting singed. Although I have thick hair, as I age it’s becoming more fragile as a result of highlights and gray coverage. This is possibly the best product I have ever used, I was so amazed after the first use, that I phoned my stylist and asked that he purchase the “for salon use only” to use on me. I simply love, lov...

I've been dying my hair for 30 years and have recently decided to let my natural color shine. In order to help it along I purchased k18 and it really does work. Where most conditioners will work on the surface and wash out I do notice that k18 has improved my hair. I am trying to use it every third or fourth shampoo. Keep you posted, but loving it so far! Beautiful packaging and presentation product as well.

This is my second review for K18 Leave-In Molecular Repair Hair as I've just bought my second bottle. I love this product. It delivers on it's promise to help repair damaged hair. When I first tried it, I seriously thought I would never get a comb through my hair as it's long, thick. The directions state not to use conditioner, just wash your hair & towel dry. After following the directions for the amount to use I was actually in shock. The comb basically floated through the tangles and never on...

It really does give you instant results. My hair has blond highlights. Now after several years the bottom half is a lot dryer looking. K18 gives it that healthy youthful look. Only drawback is you need quicker shipping.

I get my hair highlighted every month leaving my hair a bit dry. This product makes my look and feel like silk. I wish I could get bigger items, I’m addicted.

My hair feels great and truly looks healthier. I have been getting my hair highlighted/ colored for over 30 years and I couldn’t be happier with the results. I have been using it for 3 weeks now and I am grateful that my hairdresser told me about this product

I the directions to the T and my hair felt great after the first use. I have relaxed mid back length hair that needed some extra TLC and really had no idea how to even attempt that till I ran across an informercial for this product and decided to try it. Glad I did it is pricy but it made such a difference in my hair. My hair is happy I tried it.

I have baby fine hair that I recently decided to bleach/dye a beautiful rainbow of colors. This product has brought back strength and resiliency to my strands. I feel comfortable experimenting with future colors, knowing that I have this product to protect and improve my hair. Frankly, I would recommend this product to anyone with fine hair, even if it's not color treated. I really feel like it's improved my hair quality overall including increased strength and manageability. I know it's no...

I don’t usually write reviews but I’m floored by the effects of K-18. Practically after one use I could just notice a drastic difference in my hair. Bleach and hair color had destroyed my hair and made it brittle and gummy but not I can see the life and shine back in my Hair. I’m a customer for life

This product is a game changer! My hair was very damaged from an over processed highlight. One week of using k18 and I have my conditioned hair back! I’m amazed and would recommend this product.

My hair is in need of major repair . Heat, highlights, curling wands, ugh!! The first time I used it I was soooooooo pleasantly surprised !! Finally a product that does what it claims!! I will use it for every wash until I can just use it 2x per week. I even asked my stylist to get the spray before I color. I am very happy with the results and I would recommend it to everyone whom is in desperate need of hair repair !! ⭐️⭐️⭐️⭐️⭐️

In only a few applications, It has brought my hair that had been affected by sun, color, tint and styling back to the soft, youthful, smooth feeling and looking hair I’ve been longing for!! I’m excited to see how wonderful the hair will be with additional use. This is by far, the BEST product I’ve had the good fortune to try!

I wasn’t actively seeking hair treatment but I am trying to grow my hair out. I didn’t go into this expecting anything really but now that I tried it , I can’t go back. I haven’t tried anything else other than biotin and collagen hair masks so this is like wow. Just wow. My hair is so smooth and feels great. I hope it helps me to grow it out.

I cannot believe how amazing this product is. I am 56 years old and have been dying my hair since I was 16 and at this age I had just accepted the fact that my hair will forever be dull, brittle and lifeless. And then I came across this product and it has forever changed my life. My hair is back to where it was before I started dying it. It is soft like silk, healthy, and so shiny. And if possible it seems like it is still getting better and better with every use. I will definitely be a custome...

This is magical! My first use was a few days before I was going to color - you know how your hair gets dry, frizzy, washed out when you NEED to color and conditioning is critical, right? Well, not after K-12! Hair was smooth, shiny and vibrant! Color day. I'm thinking - what the heck, I'll use this instead of the color conditioner. My hair is fabulous. Directions say use for 4-6 washes. Any reason I can't use every wash? Thank you for a fabulous product!

Feels like my hair has been deeply conditioned and revived. My natural curl sprung into action as I just let it air dry. I am impressed at how great my hair felt afterwards. Just about ready for my third application. Bye bye, Olaplex. There’s a new Hair Sheriff in my house.

Love it!!!! I was super skeptical to try khairprep because there are so many products that promise to repair and protect hair and dont deliver on the promise or they weigh hair down too much. This is the holy grail! My hair is healthy, bouncy and full of volume.

I did not like touching my hair because it felt dry and a little weird because I color my hair and as a result of thyroid issues. Now, my hair feels soft, thick or full & shiny. Thank you so much!

My daughter is a stylist and recommended khairpep. Absolutely LOVE IT! My hair is super fine and leave-in conditioners usually result in flat, dirty looking hair within an hour. Khairpep left my hair soft, shiny an looking great all day

I love the masque...completely changed my blonde processed hair. I'd love to have the serum for when you bleach it to take to my salon...I told them about it, but not sure they are going to buy. I'd love to take it in there on my next appt and use it to show them.
