I have HE LTR, Suave, Tresemme moisture rich, and HE Hello Hydration. When you co-wash with these do any of you add oils such as olive oil and JBCO. If so would this cause build up if you scrub your scalp with this? Also if this method is used by some how do u add these? For example do u add some to the entire bottle or just to the amount you use to co wash with? Off topic but is Suave tropical coconut considered a protein condish b/c my thick 4ab natural hair is alway in need of moisture moisture moisture
