Improves shaving efficiency: Changing the shaving head is sharper, making shaving faster, easier and less shaving time. Reduces skin irritation and cut risk: Old blades may become dull over time. Replacing the shaving head can reduce this. Improved shaving results: Replace the shaving head to better follow the contours of the face, capture and shave shorter, finer hairs, and ensure smooth, residue-free skin after shaving. Extend the life of your shaver: Replacing your shaver head regularly can help protect the shaver's internal mechanics from excessive wear and tear, extending the life of your shaver as a whole. Optimized battery life (for electric shavers): For electric shavers, a clean, sharp head reduces the workload on the motor, and replacing the shaving head indirectly extends battery life.
