Honestly NJoy you did amazingly well with those 3 textures for so long. Its a fresh start, think about how much easier it will be now can't wait to see pics of your gorgeous all natchal!
I don't know exactly (it's pressed right now), but I believe it's roughly shoulder length. APL/BSL in 15 months is amazing! I'm 5'10" so maybe that factors in a bit.
NJoy...I bet you will surprise yourself as to how easy detangling, styling and working with your natural hair will be. Congratulations. Although you did not plan to BC now, it will grow healthy and faster than you think.
