In 18 months, your Braun razor will have cut an average of 6 million hairs. This causes a gradual wear on the cutting parts, which can make shaving less comfortable. That's why Braun recommends replacing your razor cartridge with cutting blades and slats every 18 months to keep your razor in top shape. Take good care of your razor and it will take good care of you.
