Abstract
A hair retaining device comprises two co-acting virtually identical circular helical coils. Pockets are defined between the coils. In use, the device is screwed into a user's hair and the hair strands are captively retained in the pockets. The two coils preferably are joined at one common end. The coils are wound on the same hand and are coaxial with each other to form the pockets therebetween. The other ends of the two coils are free and spaced apart.
Claims4
A method of fixing hair in a style including the steps of:
- providing a hair retaining device having a circular helical coil with at least two convolutions;
- arranging the hair in a selected style;
- and
- screwing the device into the hair to thereby retaining the hair in that style, wherein the hair retaining device comprises a pair of coaxial helical coils connected together at a common end, each said coil having a helical configuration extending from said common end through a distal end of each coil, the two coils being evenly spaced apart along their length and wound on the same hand, said coils having a diameter of between 8 and 15 mm and a length of between 40 and 80 mm, each said coil being formed having at least two full convolutions so that at least four hair retaining pockets are defined between the two coils, said coils having a pitch to diameter ratio of between 1:1 and 3:1, said coils being formed of a material which is sufficiently resiliently flexible to permit resilient distortion of said coils relative to each other to take place as the device is operatively screwed into a user's hair.
