You know how when you are brushing your horse, you're mind is wandering other places and you just brush the horse even if you were eating a burger? (so to speak) Well, when you pet her head, do that.
Don't pay any attention to where you are petting - I mean, pay attention but take all your focus off the horse, so that way the horse knows you don't mean any harm and such.
There is two ways - that I know that work - to help this, but the second one has slipped my mind. I will post about it later when I remember, haha!
1: Getting closer, and closer, and closer, and closer........
So why don't you give her a treat? (remember, you are more interested in that rainbow than the horse at the moment. So to speak.) Then maybe try rubbing her nose, working the run line from her nose to between he eyes. Then start rubbing her cheeks and over her eyes. So like rub above her eyes then run over them and to her cheeks. Then I would rub her neck or her forehead still. Then Work your way to her ears until the point to where she flinches. Then rub her neck and work your way up to that spot and right when you get to that spot, go back to her neck. Just keep working like that until she gets better with one ear. Then go on the other side and do the same thing. Also try rubbing her poll and bridle path as well.
