This is by far the best ponytail baggy method tutorial video I've seen.
The baggy method is a way of doing an extended hair treatment where the ends of the hair is left in conditioner (in a bag) for a long period of time. It's perfect for dry hair ends.
I'm sorry the music on her video was too loud. I added the video anyway because I understood it and thought it was great.
For those of you who can't hear... All she did was put olive oil and conditioner in the bag then tied it onto her ponytail. She then put a fake ponytail on top to cover it up making it nice enough to wear outside while and allowing the hair to be deep conditioned for a prolonged period of time. She then used gel to keep the front of her hair smooth. That is optional of course but she suggested it for keeping wet hair flat.
