unbrushed

Unbrushed is an adjective used to describe something that has not undergone brushing. Brushing is a manual or mechanical process that uses a brush to smooth, clean, or alter the surface or texture of a material. As a result, unbrushed items generally retain a more natural, untreated state, which can be rougher, duller, or more textured than their brushed counterparts.

Common contexts for the term include hair, fur, teeth, textiles, and surface finishes. In hair or fur, unbrushed strands may appear tangled or frizzy and exhibit a natural texture. In dental hygiene, the phrase unbrushed often refers to a lack of brushing over a period of time and can be associated with cleanliness concerns. In textiles, unbrushed fabrics have not undergone the nap-raising or brushing process, producing a flatter surface that can feel cooler or smoother depending on fiber and weave. In metal and other surfaces, an unbrushed finish lacks the directional lines produced by brushing and presents a plain, flat appearance.

Etymology and usage notes: the word is formed from the prefix un- plus brushed, with the meaning derived from the absence of the brushing process. The term is descriptive and context-dependent; it may carry neutral or negative connotations depending on the domain (for example, hygiene vs. manufacturing).
