My hair was doing GREAT. It was super long and wasn't very frizzy unless I wore it in a pony tail the day before.

I recently got my hair cut. I told her an inch and she cut off about 2.5. She normally never cuts that much off.
Ever since then, pony tails have been horrendous, frizz has been out of control, and my "bang" area isn't even curly-it's waves.

My question is why isn't my hair curling at the root and what are some alternatives to ponytails. I play tennis so no matter what, I need something to secure my hair back.

Any help would be great!!

edit: its also extremely knotted from the nape of my neck all the way to the surface of the hair in that area. it looks disgusting
