OP, I'm sorry this happened to you. Just look at it as a minor setback that you will recover from. And like others said, at least you learned your lesson and know to proceed with caution in the future. You will most likely have to learn to do it yourself if you want it done right.
I am just wondering why you want to know if you should go back to her for other services (e.g. wrap and roller set) if you told us that the end result looked like crap?
you will most likely have to find someone else who can do stellar wraps and rollersets or learn to do EVERYTHING to your hair yourself. It gets tiresome, I would imagine, but it's an investment that seems worth it. Especially considering your goals. If everytime you go to a stylist and they're just cutting what they feel like cutting (that's not really necessary) then what is the point?
Your hair looks great and I'm sure when you get back to waistlength (and beyond if that is what you desire) it will be even more beautiful.
