A hair roller comprises a housing, an electrically-powered heater, and an electrical connector. A section of hair can be wrapped around the housing and, in use, the electrically-powered heater heats the hair roller to transfer heat to the hair wrapped around the housing. The electrical connector is removably connectable to an electrical supply connector of a power applicator. In use, the electrical connector is to receive electrical energy from the electrical supply connector for delivery to the electrically-powered heater. The power applicator is configured so that the electrical energy can supplied to the electrical connector from the electrical supply connector when the hair is wrapped around the housing of the hair roller.

The invention discloses a hair straightener capable of automatically distinguishing dry and wet hair. The hair straightener comprises two heating panels, each of the two heating panels having a heating surface, the two heating surfaces cooperating with each other for clasping hair and for hair styling; a conduction assembly, provided in one of the two heating panels, and configured to detect the humidity of hair; and a circuit control system for controlling temperatures of the two heating panels upon receipt of the humidity of the hair detected by the conduction assembly. According to the invention, the temperature of the heating panels can be adjusted to an appropriate temperature after the humidity of the hair is detected, so that the hair conditions are in the best state.

Heating units for heating hair rollers are provided, as well as rollers for use therewith. An exemplary heating unit includes a housing having a lid and a lower portion, with a first magnetic core disposed within the lower portion and a second magnetic core disposed within the lid. The first magnetic core includes two parallel legs, and a plurality of conductive windings wound around one of the two legs. When the housing is closed the first and second magnetic cores together form a square closed core. When energized, the windings generate a magnetic field within the square closed core that induces an electric current in a roller disposed around the second of the two legs. An exemplary roller for use with the heating unit comprises a conductive cylinder, such as aluminum, having a diameter of at least two inches and including bristles protruding perpendicular to the exterior surface.

A hair-styling tool may include one or more pods that store liquid. For example, the hair-styling tool may include a removable, reusable water pod and/or a removable oil-formulation pod, which may correspond to a hair type of an individual. Moreover, during operation, the hair-styling tool may output or provide one or more discharges, such as: a steam discharge, an oil-formulation discharge, and/or a steam-and-oil-formulation discharge. The discharge flow may be selectable or dynamically adjusted based at least in part on the hair type of the individual, a predefined preference of the individual, and/or a predefined preference of a hair stylist. Moreover, the one or more discharges may be output of or provided from a head in the hair-styling tool. This head may include multiple prongs or tines that are used, in conjunction with the one or more discharges, to detangle or style an individual's hair.
