Hair roller

A hair roller kit comprising:

• one or more hair rollers, each hair roller comprising:
• a housing sized and shaped such that, around which a section of hair on a user's head is wrappable;
• an electrically-powered heater configured to, in use, heat the hair roller to transfer heat to the hair wrapped around the housing;
• an electrical connector, the electrical connector being removably connectable to an electrical supply connector of a power applicator,
• wherein the electrical connector is configured to, in use, receive electrical energy from the electrical supply connector for delivery to the electrically-powered heater, and
• wherein the power applicator is configured so that the electrical energy can be supplied to the electrical connector from the electrical supply connector when the hair is wrapped around the housing of the hair roller;
• and
• a power applicator to apply electrical energy to the hair rollers, in use, the power applicator comprising:
• an electrical supply connector, the electrical supply connector being removably connectable to the electrical connector of the hair roller, wherein the electrical supply connector is configured to, in use, deliver electrical energy to the electrical connector for delivery to the electrically-powered heater, and wherein the power applicator is configured so that the electrical energy can be supplied to the electrical connector when a section of hair on a user's head is wrapped around the hair roller;
• an electrical energy source to supply electrical energy to the electrical supply connector;
• and
• a control system to control the supply of electrical energy to the electrical supply connector.
