Long story (not so) short:
Right now I have thick, coiled hair that is about 1.5in past collarbone length. I'm in Afghanistan, and I have been wearing the same style most of the 6 months I've been here. Usually its just a curly pony-puff kind of deal, and about 2 months I wore twists. My hair unfortunately has sustained a LOT of damage I'm trying to undo currently.
Most of the damage started when I joined the Army, and I used to have a pretty decent regimen I think. I actually was promoted, comissioned, and got promoted again since I've been in these past 2 years, and I went from having long kinky natural hair that I cut to a little fro, then finally grew back into wearing a pony-puff style. When it was really long (almost at my bra strap straightened) I could do a formidable bun without my ends sticking out. My edges around my face were long enough that they laid down, even though they frizzed. The problem was overtime I damaged it- I had let strangers flatiron it to death after I tried the Brazillian Keratin Treatment, and I overused spray gel to lay my edges down until they dried out and broke.
I made the decision a year ago to cut my hair off, so I went up to a chin-length bob. It was very uneven layers because the damage I cut away was mostly the top of my head. Some of the damage I didn't cut, and a few bits of my hair is crispy/straightened out.
Last year I deployed able to wear a ponytail again. I wore it everyday and it lasted in pretty good health well until some things changed. My leave-in conditioner was Out of Stock for some time (Lush Cosmetics R&B Moisturizer). The water quality depreciated (it's recycled, disinfected, nothing you want to drink). My patience ran out (brushing my hair is a big chore once it gets past about 6 inches long)... and I got
super busy with my job.
Now my edges are broken, not thin but just broke off. My hair is dried out from roots to ends. The damaged ends I didn't cut last year are worse off than before. My curls just frizz and don't even clump together unless I over-brush them.
I really just want to have pretty waves/curls like I used to

I used to know how to bring my hair back to life, but my options are limited and I'm worried the state is permanent.
