Few people can pull of a successful hair shelf, and I'm not one of them.
It's a hairstyle that requires a lot of
gel, a good comb, and
patience.
Basically, the front of your hair must extend between one to two
inches from the
actual end of your
head parallel to the ground, forming a sort of
shelf.
The reason its called what it is is that done correctly, you can clip a pen to it and it looks oddly natural.
