Not only does it matter a lot, but I propose that anyone who's only a little bit taller than 6 ft eg 6 ft 1 6 ft 2 needs to shave off their hair so we can see if they're truly over 6 ft tall, or if they're only over 6 ft tall due to having a lot of hair height. Plenty of 5 ft 10 dudes maxing out their hair height to convince themselves they're over 6 ft. If you're the avg Sherdogger then you have great hair genetics, so your hair will grow back to normal height within a couple days, just wear a hat when in public for those 2 days so as to not embarrass yourself
Edit: forgot the avg Sherdogger is 6 ft 4, 240 lbs, so the above doesn't really apply to avg Sherdogger
