PURPOSE: To obtain a hair bundle for increasing hair having high fixing power and capable of increasing the freedom of hair style by interlocking a hair bundle to plural yarns or wires extended on a hair-knitting frame to form a braid and suspending the hair end part of the braid downward.

CONSTITUTION: A kind of braid is formed by interlocking hair bundles 8 to yarns 5, 6, 7, twisted yarns for braiding and/or wires stretched between supporting rods 1, 2 of a hair knitting frame. Hairs are suspended downward from the braid to form a knit hair. The use of the hair bundle in a wig enables free styling of the hair without forming too large knot and the breakage of the hair, etc., in spite of the firm fixing of the hair bundle.
