I cut my own hair. At least I don't feel ripped off when I'm done. They've been cutting it in this same style of layers anyway for all of my life.
I don't pony tail it but I do pull the hair to the top and trim the ends.
2c/3a?
Low porosity, medium texture.

If it smells good put it in your hair, if it tastes good spit it out!
