I grow hair fairly vigorously pretty much everywhere except the top of my head.
I was in AFROTC in college. As a minimum every Thursday we would have to be in uniform for an academic class and a "Leadership Lab" period where we would do cadet-led things, like teach Drill and Ceremonies.
In December 1981, my senior year in college, a few of us were sitting around the AFROTC cadet lounge shooting the bull about the upcoming Christmas break between semesters. Somebody pointed out that between the last Leadership Lab in December and the first one in January we would have about four weeks without required uniform wear. He further opined that it was possible that we would go on active duty right after commissioning the following May, and we were all planning on full length careers...so the last chance for any of us to grow a beard was Christmas break.
Thus was born the pledge for all of us to let it grow, reconvene in about four weeks, and see who had the best beard. Amazingly no beer was involved in this plan, probably for the best.
So off we went to finals week, two weeks of holiday, a week of registration, and then the first week of school. My beard grew in rather well if I do say so myself. It covered my face very well, no scraggly look at all, nice even brown color.
As I strolled down the hallway outside the AFROTC offices I passed my detachment commander, an active duty Lieutenant Colonel. His eyes cut sideways at me and I heard him mumble something about "safety hazard." I passed one of the NCOs assigned to the detachment and he asked me "How's the Yukon, Jack?" One of the Captains came out of his office, rolled his eyes and went right back in shaking his head.
I turned into the cadet lounge where the rest of the "competitors" had already assembled and...not a single one of them had a beard. Not even stubble. I immediately challenged them, and they sheepishly admitted that their "beards" were so puny and sparse that they gave up. I accused them all of being low-testosterone eunuchs and worse.
The really good part was that the girls LOVED my beard.

They would come up, gently run their hands over it, and coo about it. Man why didn't I think of this earlier?
The bad part was that the next day I had to shave it off to meet AFR 35-10 specs for the first Leadership Lab.
Thus endeth my bearded days.
AFROTC was indeed followed by nearly 23 years in the USAF, and now when I let it grow out, somehow it has turned white and a two day stubble ends up giving me the "homeless" look.
