One thing I really liked is how well it cleans my scalp—especially before going in with a hair mask. It leaves my scalp feeling fresh without that overly stripped, squeaky feeling you get from harsher shampoos, which I appreciated. That said, I did notice that at times my hair felt a bit dry and slightly weaker after using it. Because of that, I found it works best when you’re mindful of how much you use. A little truly goes a long way, and I had better results doing a lighter first wash followed by a slightly more thorough second shampoo. I’d recommend this shampoo for people who struggle with oiliness or have damage and breakage, since it does a good job at cleansing without completely compromising the hair. I used it long enough to see a slight improvement in my hair’s overall condition, which is a plus. However, despite the benefits, I’m not completely sold on repurchasing it. It works well, but for me, it didn’t quite stand out enough to become a staple.

Clean scalp!
I struggle a lot with finding shampoos that don’t leave my hair greasy, but this one is magic. The entire K18 line has saved my hair.
