Need Advice! Shampoo free or no way

                                                                      HELP ME! 

I am thinking of going shampoo free. My favorite shampoo changed the formula and I hate it.  I hate the others that I have bought also.  I have been thinking of going shampoo free.  Using baking soda wash and a vinegar rinse. Words of advice?   please leave a comment or a link to more info.
