Have your ever heard about agal? Do you know what is it? You would have seen Arabic men wearing ghutrah or white chadar (keffiyeh) on their heads. You would have noticed that this white scarf (keffiyeh) will not stay on their heads until a black accessory is not placed on it and, it will slip from their heads without this accessory. This black accessory is termed as agal. The significance of this agal is that it will not let the keffiyeh or handkerchief like head-scarfs, to slip from their heads. It is an Arabic term meaning rope. You may call it a strong black cord too.
Keffiyah are men scarfs which may be plain white or printed in different colors. Men in Arab use these scarfs or handkerchiefs to wear on their heads. You will find these head-scarfs on the heads of men in Saudi Arabia. It is the dress code of males living in Saudi Arabia.
A single cord is not worn on this keffiyah but it is doubled to give a better support. Sometimes, an edge or the both ends of this cord are left hanging but, these are left hanging on the back not in the front. Agal is said to be made up of hairs of camel or goat. When these hairs are braided out, they take form of this cord named as agal. But, nowadays these agal may also be made up of nylon. Agal is usually of black color. But, some scholars wear agals which are of white color.
Agal can be placed on these head-scarfs in various ways like on right or left side of the head, or in backwards or forward tilting positions.
