Horse hair

Horsehair is the long, coarse hair growing on the manes and tails of horses. It is used for various purposes, including upholstery, brushes, the bows of musical instruments, a hard-wearing fabric called haircloth, and for horsehair plaster, a wallcovering material formerly used in the construction industry and now found only in older buildings.

Horsehair can be very stiff or very fine and flexible; mane hair is generally softer and shorter than tail hair. The texture of horsehair can be influenced by the breed and management of the horse, including natural conditions such as diet or climate. Processing may also affect quality and feel.

Horsehair is a protein fiber that absorbs water slowly, but can be dyed or colored effectively using traditional dyes suitable for protein fibers. It can be felted, but not easily.

Horsehair fabrics are woven with wefts of tail hair from live horses and cotton or silk warps. Horsehair fabrics are sought for their lustre, durability and care properties and mainly used for upholstery and interiors.

Horsehair is used for the crafts of horsehair hitching, horsehair braiding, pottery, and in making jewelry items such as bracelets, necklaces, earrings and barrettes. It is used to make some wall and fine arts paintbrushes. Painting is one of the areas where horsehair is still widely used today. The horsehair is processed, cut to size and fitted to paint brushes that are used for anything from painting walls to painting pictures to be hung in galleries. Horsehair is desirable for paint brushes because of its smooth lay and ability to hold a large amount of paint acting as a reservoir and allowing the painter to stop less frequently.

Horsehair is used for violin and other stringed instrument bows. Another use in the art community comes from pottery and basket weaving where the hair is used for distinct accents and styling.
