Day 15 and it is not working – SOS!

So, I have dark blond very fine shoulder length wavy hair that has always been very fragile, breaks easily, and generally is not the greatest hair!  I thought maybe the NO POO method might really make my hair better, but it is looking just awful.  I know it might take 6 weeks to see results but I am about ready to go wash my hair.  I’ve been using the baking soda/apple cider vinegar method, or just water and my hair feels disgusting.  I rinse it all out thoroughly but it still feels like there is a film of grossness. Does anyone have any feedback or words of wisdom?
