There are alot options available to you if you plan to go natural, but first it starts off with a positive mind-state. You do not have to chop it all off to go natural, you can do what we call in the natural world a "transition" where you grow out your hair to the desired length or for the desired amount of time, then cut off the remaining damaged or relaxed hair.
Even if you decide to go natural, you can still get your hair pressed or flat ironed, though I do not recommend it as it can be incredibly damaging to all hair types, but especially black hair. You can do roller sets, braid outs, twists, etc., pretty much the same thing you can do with relaxed hair, but again it is about your frame of mind, and being willing to learn your hair and what it likes. People will say things about your natural or relaxed hair, you have to be confident enough to pull off either... Just because hair is naturally thick or coarse doesn't mean relaxing is your only option...The beautiful thing about black hair is that it comes in all textures, shapes, and length which gives it alot of versatility.
