The difference between a Japapanese perm and a Brazilian treatment? - the brazilian treatment on african american pictures

So I recently heard that a permanent Japanese long hair remains smooth. I also heard from a Brazilian hair treatment is the same. I wonder what is better, what you have straight hair for the longest time not to damage hair, and also, in the Afro-American hair. It is huge, but thank you!
