Hair Fasteners and Methods of Manufacture Thereof

A hair fastener in the form of a loop for securing a log of hair within the loop, comprising an inner elastic core and an outer fabric enveloping and loosely fitted around the inner elastic core, wherein i) the elastic core is made of a band with a width of 2 to 6 mm and a thickness of 1 to 3 mm, and made of silicone or a thermoplastic elastomer material selected from the group consisting of hydrogenated styrenic block copolymers (SEBS), thermoplastic polyurethane (TPU) and thermoplastic vulcanizates (TPV), ii) the fastener is adapted to assume a first, default, configuration in which an opening defined and surrounded by the loop has a first area and a second, fully expanded, configuration in which the opening defined and surrounded by the loop has a second area, iii) the tensile stress of the band has a value of 3.02 to 4.08 MPa, v) the band has a Shore Hardness A of 23.8 to 32.2, vi the outer fabric is sufficiently loose to provide room for maximum expansion of the band, and vii) due to a combination of dimensional configuration, physical configuration and material characteristics of the band, the band is elongateable up to 8.5 to 10 times of its original length thus enabling the first area of the loop to expand to the second area by a factor 72.3 to 100.
