Every generation of young guys does crazy-ass things with its hair.
The fifties invented pompadours, d.a.'s and flat-tops. The sixties gave us the Butch, the Beatle and a wild conglomeration of styles brilliantly described by the lyrics of the title song of Hair, The Musical:
"Let it fly in the breeze and get caught in the trees, Give a home to the fleas in my hair..."
That desperation led us (briefly, thank you, Jesus!) to the mullet.
Now, here comes the twenty first century and it's all been done. I mean all of it, everything you or anybody else can imagine -- from spikes and mohawks to weird colors and intentionally butchered patches and guys who had barbers carve symbols and entire words into their cranial filaments...
So...what's next? Nothing.
If you're already a hair stylist I strongly suggest you go to school to learn tattoo removal.
