Rihanna And Chris Brown

I am mixed with African American and Native American, I already get my hair straightened by using a hot comb. So in order to get the cut, I would have to perm it. Do you think I should?

I’m going from very long hair to short. Would a Rihanna style inverted bob suit wavy hair, as I don’t want to straighten every day. If not, does anyone have suggestions for me? My hair is thick and wavy and I have a long face.
