    • Mixed Results with K18 – What Worked and What Didn’t
I’ve tried a few K18 products, and my experience has been mixed. The K18 Detox Shampoo is a standout—it deeply cleanses without drying out my hair, and it really helped clear up product buildup. My scalp felt fresh, and my hair looked noticeably cleaner and more vibrant. The Molecular Repair Hair Mask also lived up to the hype. After just a couple uses, my hair felt softer, stronger, and healthier. It’s lightweight, and I love that it repairs without needing to be rinsed out. Unfortunately, the K18 Peptide Prep Shampoo, Conditioner, and Hair Oil didn’t work for me. They left my hair feeling dry, dull, and lifeless—even after just one use. For the price, I expected better results. Overall, I’ll stick to the Detox Shampoo and Repair Mask, but I won’t be repurchasing the rest. ... show more

    • Really good non drying clean
So I’ve been a user of k18 products for a few months and decided to get this one during the prime day event and love it. It is definitely worth the money. I’ve used the L’Oréal refine cleanser, ouai clarify shampoo, the clarifying scrub from Briogeo and this is my favorite clarifier so far for my long blonde highlighter hair. It takes out the impurities without stripping my scalp and making it too dry it too oily. I use this before I then use the k18 moisture shampoo and it’s the perfect combo for dry, oily or normal hair. It will give you a good clean without a strong scent. ... show more

    • Best thing ever
This stuff is amazing!! I’m a “raw blonde” (bleach no toner) with fine hair and a need for a lot of volumizinf products!! This product makes my hair feel sooooo good and look sooooo good!! After I use thus? I don’t have to wash my hair for two days! I usually have to shampoo daily it’s great and well worth the money! Glad my stylist turned me on to this product ... show more

    • Best Clarifying Shampoo Yet!
I recently tried the K18 PEPTIDE PREP™ Color-Safe Detox Clarifying Shampoo, and overall, I’m really impressed with how it performed. One of the standout pros is how soft and light my hair felt after using it—like a total reset! It did an amazing job of removing all the product buildup that had been weighing my hair down, which is exactly what I was hoping for from a clarifying shampoo. What surprised me most, though, was that it didn’t leave my hair feeling stripped or dry. My natural oils seemed to stay intact, which is a huge win for a product like this. On the downside, the smell isn’t my favorite. It’s not awful or repulsive by any means, just a little off-putting and not as pleasant as I’d prefer in a shampoo. That said, the results were so good that I can easily overlook the scent. If you’re looking for a clarifying shampoo that cleanses deeply without over-drying, this one’s definitely worth a try—just don’t expect a luxurious fragrance! ... show more

    • Shampoo
I like this shampoo. It cleans my hair well and leaves it feeling soft and shiny. It lasts awhile if you don’t wash your hair everyday so it makes it worth the price.

I suffer from oily hair and dandruff. I use this once a week without conditioner. This has my scalp feeling so clean after! Then I use K18 Leave in molecular repair hair mask and let sit for 4 mins then I spray Kenra Platinum Blow Dry spray and IGK Good Behavior anti-frizz spray then blow dry my hair. I spray IGK good behavior again when my hair is dry right before I straighten or curl my hair. After styling, I use K18 molecular repair hair oil. That’s my routine for hair wash day. This leaves my hair looking so healthy, soft, thick and smells so good. Definitely worth it!! Take care of your real hair girlies. ... show more

    • Miracle Shampoo!
My stylist recommended this detox shampoo because my hair had so much mineral buildup from my hard water. It felt like my hair was easily weighed down with a greasy feeling, like I could never really get it fully rinsed clean and it was so easily tangled to the point where my stylist said it was like I have Velcro hair. Using this shampoo one time made me feel like I had someone else’s hair. Suddenly my hair is much more voluminous and feels so clean. I use it 1x/week religiously and it has made an enormous difference. Can’t recommend enough! Does not wait! Just get it. ... show more
