1. A surgical hair clipper comprising:
a clipper body;
a blade assembly configured to removably connect to the clipper body, the blade assembly comprising a moveable blade configured to reciprocate to remove hair from a skin area and a blade housing that houses the moveable blade, the blade housing having a guide surface that faces the skin area during a hair removal process;
a touch sensor arranged and configured to be exposed through an opening through the guide surface for contact with the skin area during use; and
a processor that receives a signal from the touch sensor when the touch sensor contacts the skin area, wherein the processor instructs a feedback device comprising a light to provide an indication of skin contact between the touch sensor and the skin area based on the signal;
wherein the clipper body is configured to retain the touch sensor with the blade assembly removed from the clipper body, the opening through the guide surface arranged and configured to align with the touch sensor such that the touch sensor extends at least partially through the opening with the blade assembly removably connected to the clipper body.
