For the best shaving results, it is recommended to replace the shaving head every 18 months. Over time, the shaver may trim over 6 million hairs, which can gradually reduce cutting performance. The replacement head features special processing technology that enhances the overall texture and appearance of your shaver. Replacing the head helps restore the shaver’s performance and provides a better shave. Regular replacement keeps the shaver in optimal condition for years. Color as shown. Material: Plastic + Metal.
