Hair type

I need help trying to figure out my hair type. I had tight curls until I dyed my hair. I used a much stronger dye on the front and that loosened my curls, but since I used a weaker one on the back of my head, the curl pattern seems to be fine. The very bottom on the back is not curls at all. Its just very dry and puffy. One top of that is where I have my tightest curls.

My hair before I cut it and way before I dyed it:
