The tan helps a lot. Hair grows during the day and not at night. (at least this is my experience and we have all heard the term 4 o'clock afternoon shadow).
Actually, hair follicles don't know any difference between day and night, they grow at a slow, constant rate, 24/7.
In fact, for me, most of my head stubble
seems to occur at night, but it's just that it takes most of the day to get long enough to feel again. Since I'm out cold for 8 hours at night, I'm not aware of the change until I wake up and it's "suddenly" there. I think maybe facial hair just grows a little faster, so you can tell by 4 or 5pm.
