Beards
I have had a beard since I was 18 years old. Only shaved it off once for jaw surgery when I was 25.
Like everyone said, it only itches for the first couple of weeks until it grows in and the sharp edges on the hairs from shaving have rounded off. Mine mainly only itched from weeks 2-3. I shave my cheeks, under my jaw and below my lower lip to keep it shaped. I generally only shave those areas once a week, but if I let them go longer they start to itch.
