Maybe not. If like me, who at the age of 20, could go three days without shaving, in Army Basic Training, without being told by a drill sargent to shave dry out in the field! In advanced training back then, I could go four days without shaving, the inspections being less intense.
Even today, it would take me four days to grow hair on my face, the same length as some do in one day.
In Basic Training, there was one guy that was made to dry shave his face every morning between 10 and 11 am, with what looked like a 1 or 2 day old beard, sometimes having to shave in the afternoon too, even though he claimed he shaved that morning. After a week of this, his drill sargent showed up in the shower room to watch him shave and then checked him out at 10 am. Afterwards he was still required to shave in the morning and afternoon, but was allowed to use water when shaving!
