Ric, I got that picture off a website that specialized in clothing for plus sized women. I think I used the search terms "swimsuit" and "XXL" in google's image search. Maybe you can find the same picture and contact the company that runs the website and find out who the model was. Hope this helps.
As for your hair, when in doubt: Lather. Rinse. Repeat. Doing this once a day ought to keep your hair in fairly good shape.
