The be curly has a cone you have to either sulfate or if you're like me clarify to get out. That ACV or lemon crap don't cut it. It's like glued to the hair. As long as you scrub it out it's fine but if you don't it will cause stuff to sit on top of your hair and look gunky and greasy. Dimethicone does that to my hair too. Oh and bees wax that's too high on the list.
For some the A cone will do that after a while but you can no poo and get that out thankfully.
