A processor is operatively coupled to the hair treatment mechanism, the processor is mounted in the housing. A heat sensor is operatively coupled to the processor and is mounted to the housing adjacent to the hair treatment mechanism. The heat sensor faces away from the housing and is oriented such that the heat sensor is configured to face the individual when the hair treatment mechanism is in use on the hair of the individual. The processor is configured to activate the hair treatment mechanism when the heat sensor detects heat indicative of the heat sensor lying adjacent to the individual. ## Claims ### Claim 1 A hair styling device comprising: a housing; a hair treatment mechanism mounted to the housing; a processor being operatively coupled to the hair treatment mechanism, the processor being mounted in the housing; and a heat sensor being operatively coupled to the processor, the heat sensor being mounted to the housing adjacent to the hair treatment mechanism, the heat sensor facing away from the housing, the heat sensor being oriented such that the heat sensor is configured to face an individual when the hair treatment mechanism is in use on hair of the individual, the processor being configured to activate the hair treatment mechanism when the heat sensor detects heat indicative of the heat sensor lying adjacent to the individual. ### Claim 2 (depends on 1) The device of claim 1, wherein the hair treatment mechanism comprises: a trimmer positioned on an exterior of the housing, the trimmer comprising a pair of blades, each blade of the pair of blades having a plurality of cutting teeth facing a same direction, the pair of blades being movable with respect to each other to cause a shearing motion between the plurality of cutting teeth of one blade of the pair of blades and the plurality of cutting teeth of another blade of the pair of blades; and a motor being positioned in the housing and being operatively coupled to the one blade of the pair of blades. ### Claim 3 (depends on 1) The device of claim 1, wherein the processor is configured to deactivate the hair treatment mechanism when the heat sensor does not detect heat indicative of the heat sensor lying adjacent to the individual. ### Claim 4 (depends on 1) The device of claim 1, further comprising a camera being operatively coupled to the processor, the camera being mounted to the housing adjacent to the hair treatment mechanism, the camera being configured to face the individual when the hair treatment mechanism is in use on the hair of the individual. ### Claim 5 (depends on 1) The device of claim 1, further comprising an input being operatively coupled to the processor, the input comprising a sensor control, the sensor control being actuatable to alternately activate and deactivate the heat sensor. ### Claim 6 (depends on 4) The device of claim 4, further comprising an input being operatively coupled to the processor, the input comprising: a sensor control, the sensor control being actuatable to alternately activate and deactivate the heat sensor; and a camera control, the camera control being actuatable to alternately activate and deactivate the camera. ### Claim 7 (depends on 4) The device of claim 4, further comprising a transceiver being operatively coupled to the processor wherein the processor is configured to be in signal communication with a remote electronic device, the processor being configured to transmit images captured by the camera via the transceiver to the remote electronic device. ### Claim 8 (depends on 1) The device of claim 1, further comprising a power supply being electrically coupled to the processor. ### Claim 9 (depends on 8) The device of claim 8, wherein the power supply comprises a battery. ### Claim 10 (depends on 9) The device of claim 9, further comprising a charging port being electrically coupled to the battery and being mounted on the exterior of the housing. ### Claim 11 (depends on 10) The device of claim 10, further comprising a charge indicator being operatively coupled to the battery, the charge indicator being configured to indicate when the battery is charging. ### Claim 12 A hair styling device comprising: a housing; a hair treatment mechanism mounted to the housing, the hair treatment mechanism comprising: a trimmer positioned on an exterior of the housing, the trimmer comprising a pair of blades, each blade of the pair of blades having a plurality of cutting teeth facing a same direction, the pair of blades being movable with respect to each other to cause a shearing motion between the plurality of cutting teeth of one blade of the pair of blades and the plurality of cutting teeth of another blade of the pair of blades;
