I know a lot of people that pat their head because they want to make sure they're hair is still straight, most common for people who have their hair tied back.
My head itches a lot and its nothing to do with lice, just a condition and force of habit these days. But I agree on the off chance...i'd stay away.
You could always ask politely why she does it?
