  • Patent number: 11957227
    Abstract: A hair styling device for styling curly or wavy hair. The hair styling device includes a body and a plurality of tines extending from a proximate end of the body, wherein each of the plurality of tines have a same length as measured from a proximal end to an opposing distal end of a tine. The tines are rigid and non-flexible to facilitate the manipulation and styling of curly hair. In some embodiments, the tines are angled such that the proximal end of the tine extends from a first side of the body and the distal end of the tine is disposed on a second side of the body, wherein the first side and second side are opposite one another. In other embodiments, the tines include an arcuate configuration. The configuration of the tines allows for various manipulation of hair to provide differently styled curls or wavy features.

    Abstract: A hair curler which exhibits a winding member with an increasable diameter using a flag-shaped length is rolled up together with a lock of hair providing after each turn a winding member with an increased diameter depending on the thickness of the flag-shaped length and the lock of hair in-between. The number of turns can be chosen in line with a user's hair length and the desired hair curler diameter. The flag-shaped length is rolled onto the winding member together with a lock of hair increasing the winding member diameter depending on the length of the flag-shaped length and the number of turns rolled onto the winding member. Good retaining force of the curler is achieved by use of a self-gripping tape having projecting hooks, pins or bristles, which are preferably formed by cut-open loops of a nylon monofilament, thus resulting in hooks. The hooks may be deformed to mushroom-like bristles by heat process.

  • Patent number: 5285800
    Abstract: A permanent wave apparatus for curling hair includes a perm roller having a cylindrical outer surface with four equally-spaced longitudinal rows of outwardly projecting teeth positioned thereon. As the hair strands are wrapped around the roller, the rows of teeth act to provide additional compression of the hair by pressing it more firmly together between adjacent teeth with each rotation of the roller. Thus, increased compression of the hair strands is a function of both the number of rotations or wraps of a roller and the compacting action of the hair between the roller teeth. End papers having a longitudinal I-shaped slot opening therein enhance wrapping of the hair by holding the ends of all of the hair strands in place during wrapping, thereby eliminating fish hooks or bent ends, and enabling perfect wraps, even on extemely texturized cuts. Plastic slide clips serve to secure the first roller used to wrap a given section of hair to the scalp to provide increased volume of the resulting curl at the scalp.
