the white bandage around the head a symbol

every serial you watch always has someone who is hurt in the head wearing a white bandage around the head just like shekha today. what is with that bandage?
i don't even see the need for it. it is wrapped around the circumference of the head...it is so stupid and funny. why not put a bandage on the cuts he got on his face???? why only the head?

pay attention to this next time..if you watch do saliyaan everyone has it one after the train accident...so you remember???

i think it is a symbol or something....maybe..... 🤣 so funny...
