more to know

Buildup can happen from products, metals and minerals in hard water, and even scalp’s naturally occurring oils. This buildup can weigh down hair, dull color, and even cause damage, rough texture, and frizz.

This shampoo:

Deeply cleanses hair and scalp: A non-stripping lather works to unclog hair follicles while banishing dirt, oils, silicones, and things left behind from heavy product buildup including 99% of product buildup, 95% of sebum + a 76% copper reduction* after just 1 wash. *results observed on bleached hair tress after 1 wash with detox shampoo

Clears the path: Preps hair for maximum K18 Molecular Repair Leave-in Treatment results. Everything performs better on clean, clarified hair including color + chemical services, treatments, and styling products.

Great cleansing shampoo

I use it once a week and I like the clean smell and how it works with my hair. I add the K18 treatment afterwards.
