i went through a lot of old photos of my hair to see that I have been hovering around APL for years. I went from barely shoulder length to APL in 2016 and have had photos around APL since then. I have small setbacks and end up back at the same place over and over. I don't think I ever realized that I've been around APL all this time.
Hopefully you won't have any more setbacks and can get over this hump.
