How To Train Your Horses Mane To Lie On One Side

Does your horse's mane lie all over the place? Is some of it on the left side, and some on the right? Or are you growing out a roached mane? That was what I was working with, a roached mane that y horse had last year, and now I wanted him to have a mane again. But it was REALLY challenging trying to get it to lay on one side.
