K18 Peptide Prep™ Detox Shampoo - Color Safe Clarifying Shampoo for Build Up Removal - Gently Removes Dirt, Oil + Metals from Hard Water with Activated Charcoal + Salicylic Acid

I’ve tried so many clarifying shampoos that left my hair feeling like straw, and this one finally breaks the pattern. After just one use, my hair and scalp felt truly clean — all the product buildup, oils, and that dull, weighed-down feeling from hard water and styling products were gone. Yet my hair still felt soft, smooth, and healthy, not stripped or squeaky-dry. The lather is rich and satisfying, rinses clean easily, and the scent is fresh and clean without being overpowering. My color stayed vibrant (huge plus for me as a color-treated hair person), and my strands looked shinier and bouncier once dry. It creates the perfect clean canvas — my K18 mask and other treatments seem to work even better afterward. I use it once a week (or whenever my hair starts looking flat or product-heavy) and it’s become a non-negotiable in my routine. Expensive? Yes. Worth every penny? Absolutely. If you want a clarifying shampoo that actually detoxes without wrecking your hair, this is it. Highly recommend — already planning to reorder!

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.

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.

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.

Smells nice, works great, & my hair is so soft after using!

It seems to work well. I bought it to use before the repair treatment. It does not dry out my hair. It was a little pricey but I’m not singing it every day and a little goes a long way

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.

Very efficient clarifying/chelating shampoo. I use this once or twice a month because I have hair that hangs onto every mineral in my well water so just removing product buildup isn't enough, I have to have a chelating clarifier shampoo. I wish it was more affordable, but the K18 products are incredible for my hair.

Ce shampooing a montré son efficacité sur mes cheveux dès le premier lavage. A présent ils sont plus doux et mes boucles sont mieux définies. Évidement il est a coupler avec un bon shampooing traitant votre autre problématique.

Limpia mi cuero cabelludo y no reseca mi cabello

Works brilliantly.i have used it once and it worked better than I expected. I can see it being quite drying after using it over a week, but it cleans the hair and does remove the build up! My hair looks lighter and brighter and dried extremely fast compared to my usual blowdry time. I have blonde, long, fine, thick hair also.

The K18 Peptide Prep Detox Shampoo is amazing! It deeply cleanses without stripping my hair, leaving it soft, fresh, and perfectly balanced. I love that it maintains a gentle pH and preps my hair beautifully for treatments. A must-have for healthy, shiny hair!
