KK: /ˈhɛrˌnɛt/
A type of mesh or net that is worn over the hair to keep it secure and in place.
She wore a hairnet while cooking to keep her hair from falling into the food.
Hairnet → The word is formed from "hair" (from Old English *haer*, meaning the fine strands growing from the skin of humans and animals) and "net" (from Old English *net*, meaning a mesh or fabric made of threads). A hairnet is a mesh fabric used to cover and hold hair in place.
Think of 'hair' as the fine strands on your head and 'net' as a mesh that holds things together — a hairnet is a mesh that keeps your hair in place.
