  • Patent number: 7980254
    Abstract: A hair fastening and hair volume enhancing device is described which includes a thin flat strip, of bendable, lightweight flexible material having bristles on top and bottom sides thereof. A wire is positioned between sheaths of material forming the thin flat strip. The flat strip has a surface finish of a color and shine similar to a wearer's hair color and shine so that the device is imperceptible when worn by the wearer. A hair fastening and hair volume enhancing method using the device involves placing the hair device in hair, moving and/or bending the hair device in any direction, and attaching the hair to the device by means of the bristles on the surfaces of the hair device such that the hair device holds hair in place while also providing hair enhancement by holding the hair in a suspended position away from the scalp, thereby enhancing hair volume appearance while also holding hair in place.
