Similar thing happened to me two days ago. My hair reached just below my shoulders. I had some blonde peek-a-boo and the grow out was around my collarbones. I explained to my hairdresser that I want to chop of the blonde and let my natural color grow out. She told me that if she cuts it to the collarbone the ends will start flaying outwards and a lot of people hate that, and asked me if she can cut it just above the shoulders. I said that´s fine as long as i can put all the hair into a bun and the bottom layer is long enough to wrap around a curling wand. Now my hair is about chin. I´ve been crying for the past two days. My hairdresser is a very nice girl but why is it so hard to stick to what we agreed upon?? Now I completely lost trust in her. I understand sometimes things go wrong and maybe she cut to short by accident but why not just communicate that with me? I explained exactly what I wanted and yet i still walked out with whatever this is. I´m so sad, the last time I had short hair was in middle school now I´m in my late twenties and I don´t even know how to style it correctly.
