hárrar

Hárrar is the Icelandic plural noun meaning hairs. It refers to individual strands of hair as well as to hair collectively, whether on the head or elsewhere on the body. The term is used in everyday language, scientific descriptions, and medical or cosmetic contexts.

Etymology and grammar: Hárrar is formed from the base noun hár, with the standard Icelandic plural suffix -ar. The word traces back to Old Norse hár, and the plural hárrar is the usual form when speaking of multiple hairs. In sentences it functions as a plural noun describing countable or collective hair.

Biology and variation: In humans, hairs grow from follicles located in the skin. Each hair shaft extends from a root beneath the skin to the surface. Hair growth occurs in cycles, including anagen (growth), catagen (transitional), and telogen (resting). Growth rates vary by person and body region, typically around about one centimeter per month. Hair color and texture are determined largely by melanin production in the follicle. Distinctions are made between vellus hair (fine, light) and terminal hair (thicker, pigmented), which can change with age, hormones, and health.

Usage and cultural notes: In Icelandic, hárrar appears in descriptive writing about people and animals, in medical or cosmetic discussions, and in everyday speech. The term is a standard part of the lexicon for talking about hair in various contexts, from grooming to anatomy. See also hár for the singular form.
