My hair is fine and I need to sulfate wash on occasion to avoid build-up. A good ACV rinse is also helpful to me. You don't mention your hair properties so it's hard to know what products will specifically work for your hair. My hair gets a little lifeless when I've got build-up (hard water where I live) or I'm in need of a good protein treatment.
3B, fine, normal to low porosity
