Mature dread length
I was worried about shrinkage in the first few months. I had cut it to my shoulders, because I couldn't keep up with the tangles in my waist length hair. I didn't know that it would just dread if I quit. I think it was only a few weeks after that that I learned how hair dreads. I miss the length, and going even shorter was scary at the time. It's been about 9 months now, and it's mostly the same length as I started at. A couple of them have shrunk up to just 2 inches long. At some point I started welcoming shrinkage because I know that it is progress and someday it will grow long again. My hair is just past my shoulders, so similar to yours, but of course your shrinkage may vary.
