I am currently wearing a 12" silver mohawk!
At my gym one thing I've noticed with younger guys is that they look like they're getting perms. Several have super curly hair that doesn't look exactly natural. Other things I've noticed is that there's a trend to fade the sides of the head but not the entire back, and some guys are shaving a pair of thin racing stripes on the sides of their heads like you used to see back in the 80s. The perm thing is a fad that I don't quite get, but I'd rather see that than a manbun.
