How do I go "Natural"? (With my hair)?

Okay, I am african American, im not fully but that's what I claim, anyway I need someone who knows about our kind of hair to tell me how do i go natural bc ihave googled it but everything that pops up is talking about "nappy" hair and afros but my hair is course thick but wavy not "nappy" or curly... can someone help me please? because ihave been getting relaxers for years since iwas like 6 and now im 16 1/2 && its been two months since ihad a relaxer && idecided that iwould go natural because my hair eats up the relaxer after two weeks u cant tell ihad one && by it being so thick and me having a lot of new growth, when i grease my hair, its dry by the end of the day...almost like it sucks it up. My grandma even said that when iwas younger my hair would do the same thing so what do ido with it?
