You know what's fun? When your product works. We'll be breaking down key info + recommendations to help you get the most out of K18.
Your client’s hair goes through a LOT in between salon visits. Think dirt, oils, product buildup, you name it. No matter what state their hair is in, we engineered 2 color-safe shampoos for every kind of clean.
But…what kind of clean do you need at the shampoo bowl? What shampoo do you send them home with? We’re glad you asked. Adventure through this shampoo quiz to find your client’s best clean.

If you think your client has heavy buildup, it’s been a while since their last deep clean, or they’re ready to use the K18 mask at home, recommend the detox shampoo. This non-stripping lather removes any buildup holding back your creativity, and their hair happiness—like dirt, oils, product, and metals. Powered by active skincare-inspired ingredients like activated charcoal and salicylic acid, just 1 wash removes 99% product buildup, 95% sebum + 76% copper*. Woah.
Bonus: this clears the path for maximum damage repair with their K18 mask, so you can do more in their next appointment. We love a win-win.
If they shampoo more often or have little buildup, send your client home with the DAMAGE SHIELD pH protective shampoo. This certified microbiome-friendly formula removes dirt + oils without disturbing their scalp’s natural protective barrier. Powered by plant-derived surfactants that deliver the high foaming + cleansing power they love without the harshness or buildup they don’t. The result? Less frizz, and smoother, healthier hair. Nice.
Truth is, your client’s hair’s needs are constantly changing. So when it’s time to come clean at the shampoo bowl or at home, this quiz (and our pH-optimized shampoos) can deliver their cleanest, healthiest hair.
See ya soon for more FUNdamentals.
