The Philips SH50/50 replacement shaving heads allow you to maintain the performance of your rotary shaver over time. This pack includes three silver-colored heads equipped with MultiPrecision blades, which are designed to provide a clean shave by capturing hairs of different directions. The system utilizes a Super Lift & Cut action, where a dual-blade mechanism first lifts the hair and then cuts it below skin level for a smoother result. These heads are compatible with a wide range of devices, including the Shaver series 5000 and 6000, as well as AquaTouch (AT8xx, AT7xx, S5xxx) and PowerTouch (PT8xx, PT7xx) models. They also fit the Star Wars Shaver editions such as the SW57xx, SW5720, SW5710, and SW5700. Please note that they are not compatible with the S55xx series. To keep your shaving experience efficient, Philips recommends replacing these heads every two years.
