I'm suffering with heat damage from a visit to a hair salon that I'd never been to before. My natural hair that I get dyed blonde was dry and my curls, even though they aren't 100% like they were before, has bounce and the curl definition is awesome. Only after 2 uses my hair looks sooooo much better, straightened and curly!

My hair had bad breakage from using Olaplex and not offsetting with hydrating products. This is a MIRACLE product. My hair has never ever felt so soft. I honestly can’t stop touching. Thought it was just going to be another gimmick but holy cow this legitimately works. Price is pretty steep so won’t keep using it after my trial is done but highly recommend to get you back on track!

I lift my base color and add balayage, heat style often; as a result, I thought that I had to live with the ensuing damage. K18 is transformative! I saw a noticeable difference after the first use. Application couldn't be easier, and there was no weighed down feel after use. 3 months of dedicated Olaplex use couldn't compare with the results from my first use of K18. I am amazed, total HG hair product. Even my blonde is shiny! I also received excellent customer service when the dispensing pump...

I had a terrible bleach experience, I went from brown to blonde and was overprocessed with lots of breakage. 2 rounds of K18 treatments (at home), one trim, and one retone later I was transformed! I truly believe this mask saved my hair. A few years ago, I went to Hawaii and my hair got really dry after hotel shampoo + pool water + ocean water + daily washes, and it took half a year for my hair to recover. Wish I had K18 back then!!

This is without a doubt the product I have ever used! I get my hair colored every three weeks and this has restored my hair to what it looked like when I was a teenager (40 years ago) You will not be disappointed in fact you’ll be sorry you didn’t know about it sooner!

This has actually been a game-changer. I am 46 years old, I highlight and keratin my hair. This thickened my hair and made it look lustrous again, like I was 30! I have used Plex products before and this was totally different. I would recommend this to anyone.

I thought my over-dyed hair dreams were over until I tried this stuff. It SAVED my hair! I would recommend this to anyone with exhausted hay-hair that just wants to feel pretty again. Let the giant squirrels get close because today is a new hair day!

I have been using KhairPep since July 9th was my 1st treatment.. I bought the 1.7oz bottle, and I used it 2x a week for the first 6 treatments, ( 4 pumps) then, I only had to use it once a week for 2 pumps.. I have long hair... it lasted me then, for 14 treatments. I consider it money very well spent. I am in my 60’s my hair texture has changed, and I no longer color, as I really love my blond/silvers.. It requires more moisture, and TLC, and it’s more fragile, so I need something that gives it ...

My hairdresser introduced me to K18. I love this product so much, I bought a second bottle before the first one ran out. Makes my hair feel like silk WITHOUT conditioner.

After hearing about K18 and reading up on it, I tried a sample size prior to a major hair color double-process service. I shampooed my hair the day before and applied K18, then let it air dry. My stylist did the first color process (lightening from warm level 9 - not including the salt and pepper roots - to lightest level 10). After processing, she shampooed, did a deep-conditioning treatment (not K18) then did the second color process (icy white to the level 10, plus a separate process to the s...

I love this! My hair has completely changed. It has so much more volume and feels and looks so much healthier. Can't be happier. I ordered more and got some for my mom too!

I was a red head before pandemic. While things were shut down decided to embrace my silver roots moving forward the left over red was getting brassy so i lifted it with bleach which dried out my hair. K-18 gave my hair the much needed moisture and repaired it. Been using it almost 2 months now LOVE IT

My daughter is a hair stylist and has been helping me transition to my natural gray. The bleaching process severely damaged my hair. Tried K18 after reading Jack Martin’s review and it does exactly what it says. My hair feels strong, soft and healthy after using it. Will definitely add this to my routine when needed.

My hair was in good shape, but I bought this on a friend's recommendation just to try it. The first time I use it, I kept texting her that my hair "was a soft as a baby's butt" over and over! The absolute best thing about it is that I have very fine, thin hair and it DOES NOT weigh my hair down when I use it! It is fabulous stuff (and my hair looks and feels super healthy!).

This works great!! The ends of my hair were so dry and brittle and were breaking off so badly (too much heat styling). And now they feel as healthy as my roots. I’ll definitely be getting the larger size now!

Because I’m currently not forced to travel for work, I decided to have my red/red hair changed to pink. It took 3 sessions, 2 different color removers and 3 applications of bleach to remove the red and lift my base color enough to color it pink. My hair was finally pink, it was also fried. My normally thick, coarse, wavy hair was dry, whisky and full of static. I had sticker shock at the price, but now that I’ve used the K 18, totally worth it. My hair is soft, thick, wavy, shiny. I hardly had ...

I have tried Olaplex (all iterations, which made my hair like straw); and other facsimiles. Nothing has done to my hair the miracle that K18hair has done! I have bleached, frizzy, wavy/curly, dry mid-back length hair and this product made it feel like silk! I look forward to additional K18 products if any are in the plans!

This product literally transformed my hair, which is so fine it’s like feathers. The ends were dry and broken. I had to sleep on a satin pillowcase to prevent more breakage. Now it feels like a child’s hair, soft and smooth and silky. I really can’t get over how much it has changed the structure of my hair! Do you have an affiliate program? I want to shout it from the rooftops!

The repair this product has given my hair is AMAZING!!! The visible difference in the first use within 4 minutes of using this mask took my breath away. I love that the mist doesn’t affect your processing time either.

I had a horrible hair experience that caused some serious damage to my hair. I tired this product and it worked good. I noticed a difference. But as damaged as my hair was I don’t think it did enough on its own. So I paired it with olaplex shampoo and conditioner and was alternating with olaplex no3. That made a huge improvement and fast. My stylist was quite impressed with the improvement (my hair was really bad).

Love K18 First time i was hesitant with the instructions of no conditioner. Ok so i did that , applied a dime size amount, let it soak in ten minutes then blow dried my hair. Fantastic, shiny soft and felt much better than in years. Im on my 5th treatment! Addicted I will now be using every few shampoos! Great investment

So much better than olaplex . Less time so easy and smooth soft hair. I have fine bleached hair and I have already asked my colorist if she would use this on me. Her answer was “ I’ve already ordered it”

I have tried alot of things on this baby fine hair of mine. We get frizzy no matter the time of day if it's raining, cold, hot. Well with the first use I saw something happening. Then with the second use I don't have frizzies anymore. Hope the 3rd has more surprises. If you haven't made a shampoo please HURRY UP AND DO SO.

Love this! Don’t wait to try it. A small investment for anyone wanting to improve their hair long term. Especially true with the option to buy a small sample size to make sure it’s right for you... at 2-3 tries it’s a no brainer. I bought the large size immediately after I finished my sample. My hair is already softer.

I have been lightening my hair for years. It felt terrible! When it was wet it was stringy and mushy. After a few uses of k18 it is healthier and looks and feels better than it has since I started lightening. This is going to take the industry by storm!

I was unsure and concerned about changing the way I manage my hair treatment. Although once I tried the K-18 I was hooked. Love the volume and the feel of my hair as it begins to heal.

I love K18 so much! My salon started using it during my appointments and I had to buy some for myself. I have been bleaching my hair for years and using K18 every few shampoos has it feeling and looking healthier and smoother than ever.

This helped my dry damaged hair tremendously! I've recommended it to at least 5 people already. I have used Olaplex in the past and this actually worked better on me. I am a loyal customer now!

Since using k18 my hair is so much healthier, softer, shinier and as a bonus it smells better, not sure if there is a correlation but it’s such great feeling to have healthy hair. Like, who’s hair is this??!!!

Love how it makes my hair feel and look! At first I was skeptical about not using conditioner after shampoo, but each time I use it my hair adjusts and easy to comb through afterwards.

My hair is severely damaged from over-processing, and I thought I would have to cut it all off. The very first time I tried k18, it felt like a miracle. I have tried so many products that claim to repair damage, and this was the first thing to actually work. My hair feels soft and healthy, and it actually moves and shines again. I will never stop using it and recommend it to all of my other platinum friends.

I am in my late 50's and have noticed so much change in my hair. K18 is exactly what I needed to obtain a fresh healthy look. I shampoo and use K18. No other products need. I love it!

I wish I took a before photo. Because I seriously nuked my hair from bleach. It was at ramen noodle stage, and just falling off. I figured I would try this as a last resort, before I just went through with a big trim/cut. So glad I did! It improved by about 30% after the first treatment. Still felt like straw and rough, but there was improvement. I've completed my 3rd treatment, and my hair is amazingly soft and healthy looking. Even my split ends have improved! I can't wait to do my 4th treatme...

Back in January 2020 a hairdresser bleached my hair so bad is was breaking off, dry and just horrible. I was devastated tried so many products and stumbled on this. After my second use I honestly could not believe the texture it was soft and smooth felt like my hair again. THANK YOU!!! I am now a Loyal customer.

This stuff is magic! I have fine, damaged from bleach, and tons of time in the ocean, I had it lightened a month ago and and it made my hair soo dry and damaged I thought I was going to have to chop it and figured before I do it I’ll try this K18Hair stuff and holy crap does it work! My hair has never felt so good in my adult life and I’m only on my second use, needless to say, I ordered the full size and I’m sure it’s worth every penny 🙏

I have very thick, wavy, and coarse hair. I must be honest, the first few times I used this I didn't use enough... it didn't seem to be much different but recently I used almost the entire small treatment tube on my just shampooed hair and wow! My hair is so manageable! It's smoother, shiny and feels great! I've read such good things about this that I came to the conclusion that I must not have used enough of it to coat my thick hair. I can't afford to put out 75 at the moment to buy the l...
