Good products for African-American permed hair? What and what not to do with African-America permed hair?

okay so i got my hair permed when i was 12 (im 14 now) and i go to the hair salon like every other week you know just to get a wash and rinse and a touch up once every month. my hair has been through A LOT. my hair is doing pretty good now but at first I had a lot of breakage and I had to get a really big awkward haircut once (I didnt know how awkward it was at the time lol). but anyways, it's been like...2 years I think for my perm. at first I just got plats and braids like every other girl haha. i've never had weave or anything like that. my hair is about the length of my whole head. it doesnt go all the way down to my shoulder. but i get trims and stuff to keep it growing. im just wondering, is there anything i can do at home to keep it up? you know, make sure it's healthy. because the next thing i know is that i have breakage or something and im like ...i didnt do anything to my hair so how could i have breakage (i dont have breakage right now) but my hair dresser gave me something to use on my hair at home just to make it shiny and i rarely wash it on my own. i just wanna know what and what not do with it. i know this was a long question ahaha but yeahh thanks for reading :D
