Snood is a type of headgear that is worn to keep hair in place. It is made up of three components: a NET, a HAIRNET, and a hairband. The NET is a three-letter word meaning a fabric of cord or wire mesh, while the HAIRNET is a seven-letter word meaning a small NET worn over the hair to keep it in place. The hairband is an eight-letter word meaning a band of fabric or elastic worn around the head to hold the hair in place. Together, these three components form a snood, which is a type of headgear used to keep hair in place.
