The cut involves shaving hair off the child’s crown until he begins to resemble a balding senior citizen, inviting that unique brand of adolescent humiliation that can only come from teasing classmates and unwanted attention.

Supporters say it’s the perfect punishment for misbehaving kids who want to “act grown.”

Fredrick, the A-1 Kutz co-owner and a 34-year-old father of three, said he decided to advertise the cut after he used the unique disciplinary measure on his 12-year-old son, Rushawn, last fall — and saw immediate results. Rushawn’s grades, which had fallen, “dramatically skyrocketed” after he got his old-man haircut, Frederick said.
