Hårfestet

Hårfestet is a term used in Norwegian- and Danish-speaking contexts to describe the point at which a hair strand is anchored to the skin or scalp. The word combines hå r meaning hair and festet meaning fixed or attached, and it can be used in everyday language as well as in more technical discussions.

In biology, the standard term for this region is the hair follicle, a complex structure in the skin that supports hair growth. A follicle includes the hair bulb at the base, the hair root within the follicle, and associated structures such as the sebaceous gland and the arrector pili muscle. The hair shaft extends upward through the skin and becomes visible as hair.

In cosmetology, hårfestet is sometimes used to refer to the point at which hair is attached in extensions, wigs, or hairpieces, though terminology varies by country and practice. Methods of attachment can include sewing, bonding, micro-linking, or tape, all designed to stabilize the added hair while preserving the environment around the natural follicle.

Etymology: the term is formed from hå r (hair) and festet (the fixed/attached part), reflecting its general meaning of the hair’s point of attachment. The usage of hårfestet is not standardized across languages, and in medical literature the preferred term remains the hair follicle.
