Thorough cleanse without stripping — perfect for my hair
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 drynessGreat prep for repair/bonding treatmentsClean scent, good latherSafe for color-treated and damaged hairA little goes a long way❌ Cons:Not intended for everyday use — best 1–2x per week (but that’s typical for clarifying products)

“The best detox shampoo I’ve tried”
I just used this K18 Detox Shampoo and I could see and feel the difference instantly. Even though it’s a detox shampoo, it didn’t leave my hair dry or stripped at all. My hair feels incredibly clean, light, and soft at the same time.What I love most is the fresh, healthy feeling it leaves on my scalp and hair — it feels like a true reset without that harsh, squeaky dryness that most clarifying shampoos cause. My hair looks smoother, shinier, and much easier to manage after just one use.I’m not an influencer, just a real buyer, and I’m honestly impressed with how well this works. If you’re dealing with buildup or want your hair to feel clean and healthy again, this is absolutely worth it.

Great product for hair and wigs!
I use this shampoo on my natural hair and my wigs when I have build up in my hair and it leaves my hair and wigs super clean and buildup free.It is drying though so make sure to follow up with a good conditioner! But effective for sure!

But it, especially on sale
It is pricy, so I got it on prime day. However, it is worthy the price. Follow the instructions, use it once a week, you can feel the cleanness of scalp.

It’s my first clarifying shampoo to use so I don’t know what to expect but it did clean my hair
I usually use scalp scrubs, but this is my first clarifying shampoo, it did the job of cleaning my hair very well. I bought it to use the K18 treatment. So I didn’t use conditioner or mask after. It did make my hair dry but also my hair still have a bit of dryness on the ends from highlights I did a year ago. However after using the mask my hair was good to use, so I guess I will just use this shampoo when am using the K18 treatment mask. Lately I usually have a bit of oily roots after the day I shower as I do make scalp oiling and hair and feel that other shampoos don’t really get rid of all of the oil, so I feel this shampoo is good to use after oiling hair as it really gets all of the oils out. I have a long and very very thick hair and usually my hair takes long to dry but when I used this my hair dryer very fast. I think this shampoo should be used maybe maximum twice or once a month, as it really does what it say it cleans your hair from everything, and it’s a good thing to use before K18 treatment mask. It’s considered affordable for me the bottle would last me for months personally as I would use it twice a month, I think people who have oily scalp should definitely use it more as usually the second day after I put oil on my hair, my roots are oily, but after I used this one it’s not oily at all.

Love this shampoo, it’ll be my life long choice!
AI actually selected this shampoo for me after I answered questions and took pictures of my s alp and hair. It’s been two weeks, and major difference in the quality of my hair. I also use a clarifying shampoo once a month. But this shampoo makes my hair thicker, softer, more volume, and hydrated! I also have really oily hair and I only have to wash twice a week and my hair doesn’t get oily! My hair is bright and shiny too!

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!

Het item is nooit aangekomen. In het systeem stond dat het was vertraagd. Nu stuurt de verkoper een linkje van Post Nl dat het is verstuurd. Maar het pakket heb ik nooit ontvangen en staat nog steeds in het systeem als niet geleverd.
