Hi - I think you may be using too many conditioners. I have fine 3a porous hair and I co wash - if I feel my hair needs it after the co wash I'll do a quick rinse out - I don't use a leave in as my hair gets too soft and then too flat. I would miss out your leave in to start and see if that makes a difference.
