Replacement Shaving Head Unit for use with the Philips Sensotouch 3D Shavers from Philips. To maintain the maximum performance from your Philips shaver, replace your shaving heads every 2 years. GyroFlex 3D contour-following heads adjust seamlessly to every curve of your face, minimising pressure and irritation on your skin. The three shaving tracks of the Triple-Track shaving heads offer 50% more shaving surface than standard, single track rotary shaving heads. Get a close shave that minimises skin irritation. The shaving head has 3 specialised tracks: slots for normal hair, channels for long or flat laying hair and holes for the shortest stubble on your face. For use with the Philips RQ1250, RQ1260 and RQ1280 sensotouch shavers.
