Hey Dressage!
I've found that a NEW men's razor and men's shaving cream or even hair conditioner to shave with works the best for keeping irritation to a minimum. For some reason, the men's products seem to work better in that regard.
By the way, I love love love your avatar and handle name. I love horses and I love dressage. Beautiful sport.
Seems like you've got lots of help with your answer. I agree a search will give you even more info.
