A snood (/snuːd/) is a type of traditionally female headgear designed to hold the hair in a cloth or yarn bag. In the most common form, the headgear resembles a close-fitting hood worn over the back of the head. It is similar to a hairnet, but snoods typically have a looser fit, a much coarser mesh, and noticeably thicker yarn. A tighter-mesh band may cover the forehead or crown, then run behind the ears, and under the nape of the neck. A sack of sorts dangles from this band, covering and containing the fall of long hair gathered at the back. A snood sometimes was made of solid fabric, but more often of loosely knitted yarn or other net-like material. Historically (and in some cultures still in use today) a small bag of fine thread—netted, tatted, knitted, crocheted, or knotted (see macramé)— enclosed a bob of long hair on the back of the head or held it close to the nape.
