Best Shaving Effect: For optimal shaving results, we recommend replacing the shaving head every 18 months. Over 18 months, your electric shaver may trim over 6 million hairs, which can gradually reduce cutting performance. Special Processing Technology: The replacement head features special processing technology that enhances the appearance and texture of your shaver. Restore Performance: Replacing the head helps restore your shaver’s performance for a better shaving experience. Regular replacement keeps the shaver in optimal condition for years.
