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. The light-filtering member is detachably connected to the main body, so that users can easily replace the light-filtering members of different wavelengths by simply inserting and pulling, which solves the problem that functions of the existing household hair-removal devices cannot be easily switched. In addition, the sensing element is disposed on the light-filtering member, which is easy to set different combinations of the sensing elements according to multiple functions, and can mass-produce the light-filtering member to reduce the cost of production.
