No beard stubble in the sink
No stubble in the sink, no shaving cream behind the ear or on the shirt:
- Stick a shaving mirror into your shower with double-sided tape.
- Take a shower, wash your hair and face with shampoo and warm water, and do all the other things you do while showering.
- Shaving cream on your face and shaving will be the softest and cleanest shave you've ever had.
- Take a shower again.
The fogging of the mirror can be avoided for a short time, rubbing a pinch of shaving cream on the mirror --- of course, so little that you can still see clearly.
