Troubleshooting How do I use the shaving head of my Philips epilator? The shaving head is for shaving the delicate parts of your body, such as the underarms and bikini areas, in a comfortable and gentle way. How to use: Place the shaving head on the epilator and press until you hear a click. Switch on the epilator by selecting speed II. Place the shaving head on your skin and move it slowly and smoothly against the direction of hair growth. Make sure that the whole shaving head is touching your skin.
