I'll just use a scissor to cut some parts, if they became REALLY long, but nothing more than this
So what's the point of someone cuting his hair, especially SHORT?
Especially this "buzz cut" is making you very ordinary and common... one with the masses. And your head resembles an EGG. Not that i've not tried this haircut.
My mom used to cut my hair like that when i was a kid, and it was ridiculous!!! Fortunately now that i grew up she cannot do this anymore.
