Hair breakage, what can I do?

I take extremely good care of my hair. I've grown it out to several inches past my shoulder, from it being only an inch or so long. Since it was cut off, I planned to quit dying it (which I've lived up to), to see what it would be like long and untreated. I don't blow dry, or flat-iron. It looks pretty good surprisingly for what I do to it, or lack there of. I don't over do anything to keep it in good condition. I'm crazy about my hair being perfect, and to me, this is the best way to do it. I have places where my hair has broken from the occasional blow-dries, or brushing, basically there's flyaway's, not to be mistaken with frizz, and its not mostly at the top of my head like most people, but more a couple inches from the top. It drives me crazy because the rest of it looks great. There's a lot of things people use, cholesterol, mayo, eggs, avocados, deep conditioners. I want to know what will fix my hair, the best, the quickest, and in a way that won't damage it in the long run i.e. straightening. I'm apso seeking tips or secrets that other people use to keep their hair looking awesome, shiny and breakage free. Thanks for the help.
