Comfort: Some blade heads come with a lubricating strip, which can reduce friction and enhance comfort during the shaving process. Maintenance: Keep the blade head dry after use, clean it regularly, and store it properly to extend its lifespan. Replacement Frequency: Depending on personal usage frequency and blade wear, it is recommended to replace the blade head regularly to ensure the best shaving results.
