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!

The fact that this was the first and only detoxifying shampoo that I've ever used, causing it to be my favorite in a one-and-done type of deal, is amazing. Not only does it lather pretty well but I literally can feel my hair and scalp being cleansed, cleaned, and washed healthily, if that makes sense. It probably only takes two to three washes for me to feel like that but sometimes I do a fourth just in case. And with this one, a little does actually go a long way, especially after the initial wash. It does very well on my scalp. I have no adverse reactions and the scent of it is actually pretty decent for me. It's very mild as well. Now I'm not a huge fan of the price of this detoxifying shampoo; however, compared to some other detoxifying shampoos I researched, this one is right up my alley with proven results. The bottle size appears small but there's actually a lot of content in it. In my opinion you get a good value for your money. The color of the shampoo is different from what I'm used to. However, as long as it works, I like it, and it does what it's supposed to do (which is to detox my hair and scalp), I don't care if it looks like the color of the planet Mars. Most definitely a 10/10 recommend.

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.

The only shampoo that I actually felt a difference after one use! I live in the city and have hard water this is the perfect detox without the hassle of changing my shower head. A little goes such a long way this will last a very long timer definitely worth the money.

After testing the K18 Peptide Prep Detox Shampoo for two weeks, I’m genuinely impressed with its performance. As someone with color-treated, heat-styled hair, I’m always looking for products that detox the scalp and strands without leaving my hair feeling dry or over-cleansed — and this delivered exactly that. Cleansing Power: This shampoo provides a deep, clarifying cleanse that removes product buildup, excess oil, and environmental residue in just one wash. My scalp felt noticeably cleaner, and my hair had more natural volume at the roots. It’s strong enough to reset your hair without feeling harsh or over-drying. Gentleness & Formula: Despite the deep-cleaning effect, it doesn’t strip the hair. It’s sulfate-free and feels balanced — no squeaky or tangled feeling afterward. It lathers well with just a small amount, and the clean, subtle scent is refreshing without being overwhelming. Compatibility: It works especially well as a prep step before using bond-building or peptide-based treatments like the K18 leave-in molecular repair mask. I noticed that post-shampoo treatments seemed to absorb better and left my hair feeling smoother and stronger. ✅ Pros: Deep-cleansing without dryness Great prep for repair/bonding treatments Clean scent, good lather Safe for color-treated and damaged hair A little goes a long way ❌ Cons: Not intended for everyday use — best 1–2x per week (but that’s typical for clarifying products)

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.

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.

💓💓

I love this shampoo . My hair is curly but unhealthy fragile broken and split ends . So I was worry to use it to make my hair more dry but actualy I don't know how it work . After I use it although it make my hair extremely clean like I never felt befor but still don't make it dry at all .my hair just so clean and I love this feeling . Just do not use it more than one time if you gonna use it with the k18 leave in / or once in month to detox your hair from the harm material from water, product and air
