Lots of people who used to rock long hair running around with none or buzzed these days.
I always sorta wondered just how many of the shaggy headed rockers were sporting wigs though. It takes YEARS to grow a mane out to those proportions, and not everyone can do it. Mine just got bushy when I tried around age 21. I'm like a sheep. It doesn't even get huge,it just grows out to about motorcycle helmet size and then starts getting denser.
