A punch perm (パンチパーマ panchi pāma ) is a type of tightly permed male hairstyle in Japan that was popular among yakuza (mafia), chinpira (low-level mafia), bōsōzoku (motorcycle gang members), truck drivers, construction workers, and enka singers, from the 1960s till the mid-1990s. This hair style probably got its name from "needle punch carpeting", a type of floor covering with a short and tightly curled nap.
The punch perm began to fall out of usage as a result of its general association with the yakuza, as well as normal fashion trends. These days it is extremely rare to find anyone with a punch perm, regardless of their affiliations.
A variation of the punch perm that is worn primarily by bōsōzoku is called "aippa": both sides of the forehead are shaved to create a cross between widow's peak, an afro, and an exaggerated sculpted early 1960s pompadour.
Another variant is the "iron perm". While a punch perm is created with rollers and chemicals, an iron perm is created with a heated curling iron. This hair style often involves singeing the hair.
