An agal is something that people in some countries wear on their heads to hold their headscarf or keffiyeh in place. It's like a big circle made of rope or fabric that goes on top of the scarf or keffiyeh and sits on the head. The agal helps keep the scarf or keffiyeh from falling off, especially when it's windy outside. Some people also wear agals just for style or tradition. Think of it like a headband for your headscarf or keffiyeh!
