I realize that this is kind of late in the progression of this story, but Lois has been Ultrawoman for 4 years now, right?

How did she ever figure out how to keep her hair in shape? I don't imagine Clark gave her extensive lessons before he left.

Maybe if you need some sort of 'tension reliever' you can have Lois flashback to her early attempts at 'heat-vision grooming'.
