We’ve talked a lot about the science behind clean hair and why it’s essential to overall hair health that scalp + hair are truly clean and balanced. But some of our community have been asking things like: “Hey K18, why are there two shampoos?” “Do I need to use one right after the other?” “What shampoo works for my hair?”

Today we’re going to break down the scientific “magic” of our 2 shampoos and teach you everything you need to know about when to use which and how to help your client find the best one for them—but if you fall in love with both, we won’t judge. 

QUESTION: Do you need both? 

As you may have noticed there are all kinds of shampoos in every product lineup. Ones that promise to do things like volumize or straighten. The truth? Shampoos can’t really style because they are washed out of hair so quickly, but they can clean when formulated effectively. So we decided to approach our shampoo lineup in a different way: focus on health and cleansing without stripping.

Our shampoos offer 2 levels of cleaning power. Both are pH-balanced so as not to disturb the hair or scalp and infused with the K18PEPTIDE™ to nourish strands and mitigate protein loss that can come from washing. 

The difference lies in the cleaning power + the kind of buildup each tackles. Let’s break it down.
