Disclosed is a hair curler, includes a housing, a first heating element and a driving assembly, where the first heating element is slidably arranged on the housing in the first direction, the first heating element is provided with a cavity, a sliding groove extending in a second direction is formed inside the cavity, the first direction is perpendicular to the housing, and the second direction is perpendicular to the first direction; and the driving assembly is arranged inside the cavity and includes two first connecting rods hinged to each other, the first connecting rods on the same side of the hinge shaft have the same length, one end of each of the two first connecting rods is slidably arranged inside the sliding groove, and the other end thereof is connected to the housing, thereby driving the first heating element to move up and down in the first direction.

A roller hairbrush that is separable into two parts: a hairbrush roller and a handle. The hairbrush roller has a roller body along which a plurality of bristles is oriented. Further, an ejection mechanism is housed in the roller body and is used to disengage the handle from the roller body. An engagement shaft of the handle is positioned into a receiving volume of the hairbrush roller. A plurality of lateral extrusions of the engagement shaft is slotted into a plurality of lateral channels of the receiving volume, wherein the handle is unable to rotate within the roller body. The handle includes a gripping shaft below the engagement shaft for holding the handle. Furthermore, a locking mechanism is integrated into the gripping shaft and the engagement shaft, wherein the locking mechanism secures the handle to the hairbrush roller.

Disclosed herein are devices and methods for styling hair. A hair styling device is described with a cylindrical body comprising a semi-compressible core, a smooth layer surrounding the semi-compressible core, a proximal cylindrical top end, and a distal cylindrical boom end, wherein the distal cylindrical bottom end is parallel to the proximal cylindrical top end configured on each end of the cylindrical body. The hair styling device further comprises a strap comprising a first end, and a second end, wherein the first end of the strap is fixedly attached to the cylindrical body adjacent to the proximal cylindrical top end and the second end of the strap is configured to be helically wound around the cylindrical body and removably attached to the cylindrical body adjacent to the distal cylindrical bottom end. Methods are described that allow use of the hair styling devices to dry hair and style hair either curled or straight.

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.

A hand held appliance includes a handle having an outer wall and an inner wall, a motor and a heater both housed within the inner wall, a wiring assembly including a power supply for the motor and a power supply for the heater wherein the power supply for the motor is substantially diametrically opposite the power supply for the heater within the handle. The power supply for the motor may be substantially diametrically opposite the power supply for the heater when the wiring assembly extends passed the motor. When the wiring assembly extends passed the motor, the wiring assembly may be located between the outer wall and the inner wall. The inner wall may include at least one channel extending along a radially outer surface for housing the wiring assembly and each of the at least one channel may house a wire of the wiring assembly.
