Best Shaving Effect: For optimal shaving results, replace the shaving head every 18 months. Over time, your electric shaver cuts more than 6 million hairs, which may gradually reduce cutting performance. Special Processing Technology: The replacement head uses advanced processing technology to enhance the appearance and texture of your shaver. Restore Performance: Replacing the head helps restore your shaver’s performance for a better shave. Regular replacement keeps the shaver in peak condition for years. Color as shown.
