I would skip baking Soda and vinegar and just use silicone free conditioner and, if I want, sulfate free shampoos. Not sure how the bs and vinegar may mess up your hair but I would try my suggestion. Also do a nice deep conditioning. Good silicone free conditioners include Trader Joe Tea
Tree Tingle Conditioner (my favorite detangling conditioner) and vo5 Moisture milk Conditioner (strawberry or passion fruit). My favorite deep condish is Shea Moisture curl enhancing smoothie. It is marketed as a curl styler but is better (actually excellent) as a deep conditioner.
