Getting waves has absolutely nothin to do with race, ethnicity, nationality, none of that. What is has to do with is hair texture. Repeat that to yaself a few times.
If your hair has any texture, wave or curl to it naturally before you ever started trynna wave, then the answer is yes, you can eventually achieve waves. The tighter the your curls, the smaller and more numerous your waves. If your hair is for all purposes straight, and even at lengths of 2 or 3 inches long or more is still straight and has no real wave or curl to it, then you will not get waves, period. The reason for this is because, as errybody knows, waves are curls that have been laid-down and flattened by using a du-rag, and that are aligned in rows with each other thru heavy brushing. No curls to lay down with your du-rag = no waves, no matter how long you brush and no matter how long you wolf. It's simply common sense.
Theres white boys who have achieved waves, theres hella Latinos who have achieved waves, and I've even seen an Asian with waves true story. But do not get this twisted & start thinking that every White, Latino, or Asian can get waves, because not every White, Latino or Asian has the same hair texture. There is a real real easy way to tell if u ever gonna wave -- you dont have to grow it out long or wolf for months on end to find out if you can do it. Here's how:
Simply get a #3 or #4 cut ATG (against the grain) and take a close look at how your hair behaves. If, with no duragging/training your hair whatsoever, your hair sticks straight the fuck up like a porcupine, this means your hair is for all purposes stick-straight, and you just wasting your time tying to get waves. BUT, if after getting that cut, your hair tends to lay down on its own, that means your hair has some sort of curl/wave texture to it. This is how curly/wavy hair simply behaves when short, and it means you'll get waves.

\ If u white and your hair looks like this: if you're white and it looks like this:
You wont wave. Then you good. You'll wave.
If u asian your hair looks like this: If you're asian and your hair looks like this:
You'll never get waves. You'll be spinnin in no time.
If u Latino & your hair looks like this: If you're Latino & it looks like this:
You will never dip. Then you will definitely get waves.
Now, all hair will get that laid down look with enough du-ragging, even the straightest of straight hairs, but if your hair starts to stick up straight as hell when you try to h20 meth/shower brush, you simply will never be dippin at all. If you can h20/shower brush and your hair lays down even more or stays the same laid down, then its just a matter of time and brushing before you dippin tuff
