Hydrate Shampoo or K18? Choose the step you need
One is a moisturizing cleanser; the other is a leave-in treatment. Compare their intended roles before adding either to your routine.

A dry feel is not a shopping list. Before choosing between Pureology Hydrate Shampoo and K18, decide what you are considering replacing or adding: your cleanser, or a separate treatment. These products occupy different steps.
Compare the role, then the product

Make one clear decision
- Looking for a moisturizing shampoo, and the stated hair type fits? Review Hydrate Shampoo's size and directions.
- Considering a treatment for damage associated with color, chemical services or heat? Review K18's instructions and decide whether that extra step fits your routine.
- Still unsure what you need? Keep a list of what you already use and discuss it at a consultation before adding another product.
A shampoo is one part of the routine
The American Academy of Dermatology recommends conditioner after shampooing to help with moisture and detangling. A moisturizing shampoo does not make that separate step irrelevant. On a K18 treatment day, follow K18's specific sequence instead of applying conditioner beforehand.
