Yes, one of the more endearing things that lady photoers and their companions do just before photoing themselves is pat their hair:
Next time you see a lady taking selfies, watch out for this. Chances are she’ll oblige. It never makes any difference, but they almost always do it.
I took those two photos at Piccadilly Circus yesterday afternoon. I like the scaffolding. Not good enough to be worth photoing in its own right, but a nice background to those hair-patters.
