Al Camote

You play as Rocco, an ex-moob whose family has been kidnaped by the most dangerous mafia organization led by Al Camote. Rocco is against guns, which is why he developed this method of shooting his own hair. When you shoot, you are shooting part of yourself, so your health is depleted. If you run out of hair, it means you are low on health and out of ammo. Your hair regenerates in a couple of seconds and you have to choose between shooting and risking getting easily kill or gaining some health to resist more attacks. Your health is your weapon.
