I still haven't figured out how to curl with my InStyler... It does wonders when I want to straighten my thick, relatively short hair, though. I also don't think it can really be permed that way. I think if you didn't want to curl it everyday, it would be really hard to maintain that style and it still look pretty. When I want to wear mine curly, I think using a pick on it- like those ones for when you're just getting out of the shower- helps maintain the curl and smooth it out. Also, doing a bit of cheating with wearing half up, half down styles or pinning back some of the sides would help you get by without curling it every single day.
