Co washing is also suppose to cleanse the hair from dirt and build up as well, right? But because my 4b-4c hair doesn't build up as quickly as say a 2a-2b head of hair would, co-washing might get rid of the natural oils I need instead. And oils don't work for me really, My hair rejects everything it seems. Do you think daily co-washing will make my hair not feel like plastic and will help it receive product? I'm still not sure if I even have low porosity hair because my hair does sink when I completely submerge it in water. However, I do notice that there are like bubbles that form around my hair strand. I'm not too sure what that means. I heard that happens in low porosity hair. Also, what co-washing product would you recommend?
