I dislike halties in general. But this is the one place I think they have a good application. Sport used to do the same thing (scratch his face to get it off when other things were exciting him) But it was a very useful tool to get his focus back, in the same way a long line is an excellent tool when working on recalls. You can gently ensure compliance.
I don't like them for daily use.
