Abstract: A hair band is arranged for securement of a hair grouping in surrounding relationship with a hair band, including a central rigid core of memory retentent material selectively receiving a sheath thereabout to accommodate hair groupings of various sizes within the band structure. A modification of the invention includes the sheath formed with a tubular chamber filled with a temperature sensitive liquid crystal to effect visual color change in response to ambient temperature. A further hair band organization utilizes a clasp member, wherein the clasp member includes a flexible arcuate top plate spaced from a bottom latch plate, with the latch plate including a medial friction plate equivalent to the hair band formed with bifurcated end and a central body mounting a resilient sleeve thereabout to provide frictional engagement between the medial friction plate and the bottom latch plate when in an assembled configuration.
