One of the largest Highland shows in America is held in Syr, NY. Most of them are strickly washed & conditioned ( I would guess they put a sheen product on them). Lots of combing. A few are clipped. Lot of breeders are totally against this. But, they look sooooo much better. Not a lot. Just enough to tidy them up. Block out around the forehead so you can see that they can SEE. Block out the neck, shoulders, rear & bellie line. Not enough that they don't have long flowing hair, just enough that they are smoother in their appearance.
