The air here in the winter is very very dry. Every time you touch someone, you get a little zap. After brushing your hair, it stands straight up with static electricity! I have two curly haired daughters that have the frizzy fly away look going on. I think if my Curly horse were around a little more humidity he would definitely curl more.
You are right. This is an awesome breed. He's a fantastic horse for a beginner like me!
