It does that to me every once in a while too. For me it seems like I can't use it without actually styling my hair, if it's the last thing I use an let my hair air dry it does that film thing to me, or maybe that's just the only time I notice it. Under a gel or other styler I like it, especially if I diffuse, but even then I can't use it every day.
