Skeeter Head
A number 6 razor or less cutting your hair very tightly on the top of your head with a number 3 razor or less cutting your hair very tight on the sides. When you rub your head with your hand you can feel the hair push against your hand in both directions. When you wear a cap the tightly cut hair acts as velcro and keeps your hat glued on top of your head.
I had long hair then I got a skeeter head at super clips using a number 3 razor on the side and a number 6 razor on top.
