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.

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.

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 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)

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.

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.

Ottimo shampoo, ideale per capelli danneggiati! Ho provato lo *shampoo K18 ai peptidi* su consiglio di un’amica e devo dire che sono rimasta piacevolmente sorpresa dai risultati. La formula è davvero innovativa, arricchita con peptidi che aiutano a rinforzare e riparare i capelli danneggiati, specialmente se trattati chimicamente o esposti a styling frequente. Già dopo i primi lavaggi, ho notato che i miei capelli risultano più morbidi, lucidi e con una sensazione di setosità che non avevo mai sperimentato prima. Il prodotto ha una texture cremosa ma soda,che si applica facilmente e fa una leggera schiuma, ma non è eccessivamente ricca, il che lo rende adatto anche ai capelli più sottili o facilmente appesantiti. Inoltre, non lascia residui e non appesantisce i capelli, anche se si usa frequentemente. Nonostante il prezzo sia un po' più elevato rispetto ad altri shampoo sul mercato, credo che sia giustificato dalla qualità del prodotto e dai benefici che offre. La riparazione dei capelli danneggiati è una delle sue caratteristiche principali, e personalmente posso dire che i miei capelli sono diventati più forti e meno inclini alla rottura abbinati anche alla maschera della stessa linea. L'unico aspetto che potrebbe essere un po' un limite per alcune persone è che il profumo è piuttosto leggero e neutro, quindi chi cerca una fragranza più intensa potrebbe non apprezzarlo, ma per me è perfetto, soprattutto se si preferisce uno shampoo che non sovrasti il profumo di altri prodotti. Nel complesso, credo che lo shampoo K18 ai peptidi sia una scelta eccellente per chi ha capelli danneggiati o desidera un trattamento che aiuti a rinforzare la fibra capillare in modo delicato ma efficace. Ottimo prodotto che consiglio a chi cerca una cura intensa e nutriente per i propri capelli.
