Surgeons and hospital staff are often required to wear medical capillary nets.
A hairnet is a piece of net in the shape of a round cap that fits over the head to hold the hair in place. Hairnets cover the entire head, from forehead to back of neck. The main purpose of a hair net is to prevent hair from falling into food or other products. Capillary networks are used in the food industry as well as in hospitals, laboratories and some manufacturing operations.
Hairnets can be worn by men or women and most hairnets stretch to fit different head sizes. The net has an elastic edge that extends around a hairstyle. Longer hair is usually put into a bun or other hairstyle first. Hairnets are available in basic shades of colors such as brown, dark brown, black, blonde and white. The idea of a mesh hairnet is to appear almost invisible, so the color of the net should match the wearer’s hair color.
A bouffant cap fits like a hairnet but is made of semi-transparent wire-bonded material. Puffed beanies are usually white in color and are sometimes called hairnet bouffants. The word bouffant is derived from the Old French bouffer, meaning to stew. The bouffant hairstyle is a puffy haircut that was popular in both the 16th century and the 1960s. Bouffant caps also have a very bouffant shape – more so than hairnets. Some hair accessories feature nets with rhinestones or beads made to fit into a bun, but today the term hair net generally refers to the type used in food service and other industries.
The Food and Drug Administration (USFDA) lists in section 402.11 of its Food Code that “all foods employ
those should wear hair fasteners such as covers or hairnets…” Hairnets are often sold in bulk packs of 100, 144, or 1,000. Hairnets or bouffant caps are commonly used in electronics assembly and pharmaceutical applications, as well as in food service companies.
