Try the Alberto VO5 heat miracle.. im not so sure about the 'heat miracle' name but im sure its an alberto product. the one which bottle is colored red.. its a spray protection against blow dryers and flat irons. You can also try the L'oreal Hot Straight, with the pink bottle. I use the hot straight and it works for me a lot becuse it adds shine but does not look greasy. Aside from protection against the flat iron, it protects your hair from the sun. :)
