Actually, those options you mentioned are great for the middle part flow. Especially sea salt spray because when blow dried properly. It will help with flow and texture. With the blow drying techniques I would recommend either scrunching whilst diffusing or rotating the curtains backwards with a round brush. Hair creams can help with moisture and make your hair manageable which is great. There are also other options like clays, pastes, volume mousse, or even thickening sprays.
