Hair going straight..?

Destiny

So, I’ve always had curly hair. They used to be really tight coils that looked so fake to people that they would ask me if I curled my hair every morning, before I began breaking them up to make it look like I had more volume than I actually did. However, since moving to Boston for school, my curl is essentially gone. I’ve been deep conditioning it and everything to try and get it back, I even had to cut half of it off because it went so straight at the bottom that it looked like extensions. Has anyone heard of this happening or has this happened to anyone else?? I literally haven’t changed a single product that I’ve been using or anything

Pre Boston ^^
