Embodiments of the present invention relate to a hair roller which can be separated into a pair of half-cylindrical roller pieces, pairs of half-cylindrical roller pieces, and a method of storing half-cylindrical roller pieces by nesting the half-cylindrical roller pieces. The hair roller of the invention includes a whole cylindrical body separable along a vertical axis into half-cylindrical roller pieces which include a plurality of mating devices configured to selectably couple the half-cylindrical roller pieces to form the whole cylindrical body, wherein the half-cylindrical roller pieces are capable of being nested. The pair of half-cylindrical roller pieces of the invention are identical in shape, which include a plurality of tabs and orifices, where the tabs have protuberances which protrude into a corresponding orifice when the lateral edges of the pair of roller pieces are aligned.

The present disclosure is directed to open hair curlers that may be used with separate hair rollers to create two or more sizes or orientations of curls on the same length of hair. The hair curling systems include a planar body curved around a lateral axis without forming a closed cylinder. The planar body curves to create a cradle in which a complementary hair roller can sit inside. Other examples include an open curler without a distinct cradle that can still accommodate a separate hair roller. When hair is secured around a complementarily configured hair roller which is then secured in the open hair curler, the remaining hair may be curled around the outside of the open hair curler.

A hair curling rod device for creating tight spiral curls for all hair textures, with or without the use of heat includes a top member and a bottom member. The top member has a relatively flat orientation and a flat bottom side. The bottom member has a convex orientation to the top member and a substantially circular cross-section. The top member is connected to the bottom member at a first end by a U-shaped connection. The U-shaped connection biases the top member toward the bottom member. The top member has a first length and the bottom member has a second length. Where the second length is longer than the first length, where the bottom member extends beyond the top member at a second end. The bottom member has an upward angled portion at the second end where the bottom member extends beyond the top member at the second end.

A hair styling accessory includes an elongated hair board having a widened end and a narrowed end with elongated edges extending between the widened end and the narrowed end, a plurality of holes extend through the hair board from an upper surface to a lower surface. At least one end-clip having open and closed orientations and biased into the closed orientation. The at least one end-clip is designed to be positioned in the closed orientation over the narrowed end of the hair board and to grip a lock of hair against one of the upper and lower surfaces. At least one side-clip having open and closed orientations and biased into the closed orientation. The at least one side-clip is designed to be positioned in the closed orientation over one of the elongated edges of the hair board and to grip the lock of hair.

A method is provided for preparing a hair dye color mixture. The method includes: accessing a control system having at least a processor, a memory, and user input controls, the memory configured to store ingredients of a hair dye color mixture, each ingredient of the hair dye color mixture being from an initial product brand; receiving user input from the user input controls to change one or more ingredients of the hair dye color mixture from the initial product brand to one or more subsequent product brands; matching the color of the hair dye color mixture made from one or more ingredients of the initial product brand using one or more ingredients of the one or more subsequent product brands, in response to the user input; and displaying the ingredients of the hair dye color mixture in the one or more subsequent product brands on a display.

A method is provided for preparing a hair dye color mixture. The method includes: accessing a control system having at least a processor, a memory, and user input controls, the memory configured to store ingredients of a hair dye color mixture, receiving user input from the user input controls to change one or more ingredients of the hair dye color mixture to a new product brand; matching the color of the hair dye color mixture using one or more ingredients of the new product brand, in response to the user input; and displaying the ingredients of the hair dye color mixture in the new product brand on a display.

A hairstyling apparatus is provided, the apparatus including: a barrel defining a hairstyling surface and a central longitudinal axis, wherein the barrel has a first proximal end and a second distal end; a heating element in thermal communication with the barrel; and a rotating member in rotating communication with the proximal end of the barrel which rotates around the central axis of the barrel, the rotating member including a rotating plate that surrounds the proximal end of the barrel and an axially extending tab from the rotating plate along a longitudinal length of the hairstyling surface over at least a portion of longitudinal length of the hairstyling surface; wherein the rotating member includes a comb member, extending from the rotating member (such as the rotating sleeve/collar) which is attached or assembled to the tab and comprises a plurality of comb teeth arranged along the longitudinal length of the hairstyling surface.

The invention provides an apparatus for coiling hair having a working end with a plurality of spaced-apart, round monoliths. The invention also provides a method for coiling hair having the steps of bringing an apparatus for coiling hair into contact with hair to be coiled wherein the apparatus for coiling hair has a working end with a plurality of spaced-apart, round monoliths; and moving the apparatus over and through the hair in a circular motion.

A hairstyling apparatus is shown. The apparatus includes a heated barrel with a central axis. It also includes a heating element connected with the barrel and a rotating member located an end of the barrel and configured to rotate around the central axis of the barrel. The rotating member includes at least one a tab extending along a longitudinal length of the hairstyling surface over at least a portion of a longitudinally extending portion of the hairstyling surface. At least one rod with at least one comb attached to said at least one tab. The rod is heated by the heating element during use of the apparatus.

A hair setter apparatus generally includes a housing and a heater assembly having a first heat delivery rail and a second heat delivery rail mounted in the housing in spaced parallel relationship to each other. The apparatus further includes a plurality of hair setters. Each of the hair setters has a central body with opposing web plates spaced from each other to define a mounting slot extending longitudinally of the hair setter and configured to slidably couple the hair setter to one of the heat delivery rails along a longitudinal edge of one of the heat delivery rails. The hair setter is sized relative to the insert opening for insertion of the hair setter through an insert opening and onto the respective one of the heat delivery rails within the interior space of the housing.
