Shaving cartridges having thermal sensors

A shaving razor system comprising:

• a heating element for transferring heat during a shaving stroke, said heating element comprising a skin contacting surface;
• an insulating member for delivering heat to the heating element;
• an electrical circuit configured to deliver energy to the insulating member, the electrical circuit comprising a control circuit for temperature regulation;
• a power source in communication with the electrical circuit;
• a plurality of spaced apart thermal sensors directly mounted to the insulating member and positioned below the skin contacting surface, wherein the thermal sensors measure the temperature of the heating element and are in communication with the control circuit;
• the control circuit decreases power to the insulating member if an average temperature sensed by the thermal sensors is greater than or equal to a first predetermined temperature;
• and
• the control circuit decreases power to the insulating member if an individual temperature sensed by either of the thermal sensors is greater than or equal to a second predetermined temperature that is greater than the first predetermined temperature.
