How do you wash your hair with WEN?

Excuse me, could you please elaborate on the process of washing your hair with WEN? I've heard about this product but I'm not entirely sure how to incorporate it into my hair care routine. Does it replace my regular shampoo? Do I need to use a conditioner afterwards? Are there any specific steps I should follow to ensure optimal results? I'm really interested in learning more about this unique hair care method and how it can benefit my hair health.
