Its not up to the players to draw the ref's attention to it. Believe it or not they are sometimes wrong about fouls committed on them (not so much headbutts, but most other types). They're not the most impartial observers.
It's not that straightforward - referees will often chicken out of big decisions given half a chance. If Perch hadn't reacted to Reina's headbutt, I wouldn't be at all surprised to see no major action taken - perhaps a yellow each. Fact is, Reina headbutted Perch, and that's unarguably a red card - nothing that Perch did wronged Reina.
