The mustache is the growth of hair on the upper lip, a common form of facial hair among men and some animals. In English the word is usually spelled "mustache," while the variant "moustache" is common in the United Kingdom and many parts of the Commonwealth. People may wear a mustache alone or together with other facial hair such as a beard. The area where the hair grows is often described simply as the upper lip, distinct from hair on the sides of the face or the chin.

Characteristics and common styles

Mustaches come in many shapes and thicknesses. Some are narrow and finely trimmed, while others are full and bushy. Well-known names for styles include the chevron, the handlebar, the pencil, the horseshoe and the walrus. A few styles are defined by length, by how the ends are styled, or by the relation to surrounding facial hair. For example, a chin beard without a mustache is often called a goatee, while a specific combination of a pointed chin beard with a separate mustache has historically been called a Van Dyke.

Grooming and maintenance

Maintaining a mustache typically involves trimming, shaping and cleaning. Common tools include scissors, electric trimmers and razors; styling may use waxes or beard oils to hold shape. Many men shave part or all of their facial hair for personal, occupational or cultural reasons, and short, groomed mustaches have periodically returned to fashion as part of broader grooming trends.

History and origins

Facial hair styles have varied widely over time and across cultures. Early stylized mustache wearers are often associated with Iron Age Celtic peoples; ancient writers such as Diodorus Siculus described Celtic grooming practices and noted that some groups allowed the mustache to grow prominently. Other ancient and medieval societies also recorded preferences for facial hair, and mustaches have appeared in art, military portraits and cultural symbols at various times.

Cultural significance and modern examples

Mustaches have served as symbols of masculinity, adulthood, profession and social rank in different contexts. Military units and professional groups have sometimes mandated or prized specific facial-hair styles. In contemporary times, the mustache can be an element of personal identity and fashion. It has also been used in public-health and charity campaigns such as the annual Movember movement, when participants grow mustaches to raise awareness about men's health.

Distinctions, animals and notable facts

Although the term most often refers to human facial hair, similar whisker-like hair on animals is sometimes called a mustache: certain marine mammals such as walruses have prominent upper-lip whiskers. More generally, many species use vibrissae for sensing their environment, a different biological function from human facial hair. For further reading on facial hair and related topics, see entries about the animals with whiskers and specialized historical studies referenced by classical sources. For concise definitions and distinctions, consult resources on grooming, social history and style guides available through general reference links such as Iron Age summaries, articles on the Celts and cultural histories preserved by ancient chroniclers, including accounts by Diodorus Siculus. Additional practical and stylistic guidance can be found via general grooming guides and community discussions (upper lip, sides of the face, chin).
