Excellent clarifying Shampoo
Works great without drying your hair out. All of their products are wonderful. Though a bit of a learning curve. Ive read a lot of mixed results in the reviews. This particular product is to give your hair a good thorough cleaning of all those residues from hair products. It’s concentrated so you won’t need a ton. Just add a little see if it lathers add more as needed. I work it thru my hair down to the scalp. Then let it sit for bit to let it break down the residue. Slightly towel blot dry tour hair. Even better if you have a nice microfiber hair towel to just gently squeeze and blot your hair to remove excess water but leave it still damp wet. You’re not drying it. You’re preparing it for the conditioning stage in step 2. This is imprtant, Especially for curly hair. (I have a hair wrap towel from Diva Curls and I love it!) This step is to remove excess water but leave it still wet enough to help when you apply the conditioner step. Then move on to and finally the hair oil. That seals and protects the hair and helps it to be soft and shiny I think the success of these products really is dependent on using each products in its order. Just learn about each one a bit before you dive right in. They're costly and so learning how to use them will help you not burn right thru it. I have fine hair but it’s also very thick and curly. I’m almost done with my first full size order. I tried a sample kit first. Then purchased the full size shampoo the conditioner and the hair oil. And you may be shocked at the size of the conditioner as I’m a person who typically load my hair with it as I tend to have dry curly ends. And my first thought was this can’t be right it’s too small. It requires very little. I do however have to use more to really get it fully saturated. That’s my one complaint. It’s a lot of money and that took some adjusting. Hence the advice to learn about what your buying and potentially using. I’d recommend these products. I’m curious to see how this company evolves. I hope this is helpful information.

Solved All My Hair Problems
I am 71 years old with thin, baby-fine hair. I’ve always had a problem with every product designed for volume weighing my hair down. I tried K-18 on a whim and it is exactly what I’ve been looking for! My hair feels soft, is shiny, looks bouncy and hydrated and best of all, not greasy! I bought the whole line and I love it all. It’s expensive, but you only use a tiny bit. An added bonus, I see very little hair in my brush or shower and lots of baby hair growing in. The picture is just after I washed it with K18 shampoo, no conditioner, and 1 pump of the K18 leave-in mask. I imagine it would work as well for any hair type, but it is a real game changer for fine, thin hair.

Nice shampoo cleans well
This works wonders. Helps clean my hair really well. Lathers nicely and smells good. I use it ever 3-4days than once a week since I used to get greasy quick. But i have noticed this helps the greasy hair not get greasy as quickly. I could go longer than 4 days (I have alot of products I use to make my head greasy) I usually use this shampoo for the first wash and use my other shampoo for the second wash to give my hair some hydration. Overall great shampoo.

Beyond impressed
I am positively thrilled by how revitalized my hair feels after using this incredible shampoo. Initially, I hesitated, thinking perhaps the glowing reviews I had read were embellished; however, to my astonishment, this product truly lives up to the hype. The softness and overall improved condition of my hair are beyond my expectations. It's undeniable—this shampoo has transformed my hair care routine, and I am eager to incorporate it into my weekly regimen going forward. The unparalleled cleanliness and vitality my hair now exudes thanks to this remarkable product is truly a game-changer.

Amazing for Removing Build-Up Without Drying Out My Hair
I absolutely love this shampoo for my curls. I use it once a week as part of my wash-day routine, and it does an amazing job removing buildup without leaving my hair feeling stripped or dry. After using it, my hair looks healthy, shiny, and refreshed. My curls feel lighter and more defined, and the scent is incredible. It leaves my hair feeling clean while still maintaining moisture, which can be hard to find in a clarifying shampoo. This has become a staple in my hair care routine, and I highly recommend it for anyone looking to keep their hair healthy and vibrant.

Love this product leaves my scalp and hair feeling very clean
The shampoo has been a lifesaver. It definitely keeps my scalp pain. I use it once a week. Seems to keep the oil in there for a few days for me which is great because I don’t want to have to wash my extensions very often. Oh and yes, I use it on Hair Extensions. I’ve been using it for about a year on my very expensive blonde hair extensions, and I haven’t noticed that it causes any damage.

Happy Hair Happier Me
I have MS and my newest treatment is causing havoc on my hair! It became brittle, dry, shedding and I had an odd chemical smell! I researched how to help this situation and hands down, this shampoo and conditioner combo was recommended over everything else. I am so glad I purchased them. The detox shampoo left my hair feeling better to the touch and got rid of the chemical smell. I followed with the conditioner and my hair felt better than it did in months. It was smoother, shinier, and much more manageable to style. It was effective in helping me with my issues. I did find it a bit expensive, so I’m using it just every so often to make it last longer. I’m still getting great results spacing out the usage. I highly recommend this if you take medications or are having chemo to help your hair.

Are they scamming us with half full bottles or is this a manufacturing issue?
Picked up the bottle and felt really light. Opened the bottle, it’s barely even half full. Put it on my scale, 7.5 oz and this is including a very heavy bottle. Product says it’s 8.5 oz of actual product. After spending $40 for maybe 4oz of product. I am very disappointed. Not sure if it was a manufacturing issue or if they are doing this on purpose.

Highly Recommend As A Restart For Your Hair!
I never leave reviews… like ever… but K18 is magic in a bottle!!! After the shampoo I had been using for years changed its formula my hair had a meltdown and I tried very unsuccessfully to find another shampoo that would work for my hair. This only made my hair even worse… it was greasy, felt dirty even after just washing it and I was honestly lost as to what to do. Finally I came across K18 and I was a bit sticker shocked due to the price but after some research decided to give it a try and I’m so glad I did. After just one wash my hair feels cleaner than it has in a while! Definitely recommended this to anyone and everyone - it brings your hair back to a good neutral!

Gentle color safe clarifying shampoo
K18 shampoo removed my product residue, and left my hair soft, not brittle or sticky. I’ve never tried K18 shampoo, but after looking online for a good clarifying shampoo that won’t strip the color from my hair, this was highly recommended. I have to say, so far I love it, and if it continually keeps my color and my hair shiny, I will keep buying this.

My hair specialist recommended this shampoo for repair. After shampooing and towel drying (without conditioner) I add one pump of the K18 leave in molecular repair mask. Try it for yourself and see the difference. Stronger hair

Caution on usage frequency
My caution for this product is that you should not use it every day. It will strip the natural oils in your scalp and make your scalp very dry even around your face and ears. Use it sparingly once a week or once every two weeks.

Hair Feels Squeaky Clean
This clarifying shampoo leaves my hair feeling so clean! I barely use any products in my hair so I only use this once every 3-4 weeks, but if you use a lot of product in your hair then you might need it once a week. It’s pricy, but it’ll last a long time since it’s not needed every wash. I know it’s time to use this when my roots still feel a little oily after a wash with my regular shampoo.
