Hair-removal apparatus
The present disclosure relates generally to a hair-removal apparatus, which includes a main body and a light-filtering member, with at least one sensing element disposed thereon, detachably connected to the main body. When the light-filtering member is connected to the main body, the main body recognizes the sensing element.
