Everyone thinks he doesnt brush his hair, but the real issue is he does. He has thick and just fluffy hair. He brushes it dry. If you have curls, fluffy hair, anything but pin straight, you know it poofs when you brush it dry. Thats what Giyuus hair does. And of he brushed it wet it wouldn't be so fluffy, but he doesnt really know that. So, be brushes it dry and it looks so untrusted because its fluffy as fuck and he doesnt know it.
