What is porcupine haircut?

The porcupine haircut is a heavily layered hairstyle that was popular in the 1990s. The haircut gets its name from the spiky and textured appearance created by the numerous layers and chunky sections on the top of the head. This can be achieved with a razor or scissors by creating varied lengths on the top of the head while keeping the sides and back shorter. The style is often paired with bold hair colors and is a popular choice for punk or alternative fashion.
