I wouldnt use baking soda at all unless you have build up. I have heard that happens usually around the 3 month mark, but if you notice any changes in your hair its good to go ahead and clarify to start fresh. Baking soda is very drying as is any clarifying treatment it stripes your hair and its good to follow with a deep treatment. I use coconut oil all the time and just CO wash it out and havent had any problems. I have heard if oil is hard to remove off your hair to put your conditioner on dry hair and that makes getting the oil off easier. I have had breakage and I always use a protein treatment and that helps stop the breakage but not sure if your hair likes protein or not.
