Spiked hair is a hairstyle characterized by hair that is styled to stand upright, creating a spiky appearance. This look is often achieved using hair products like gel, wax, or mousse, which help to hold the hair in place. Spiked hair can vary in length and intensity, from subtle spikes to more dramatic, exaggerated styles. This hairstyle became popular in the late 20th century, especially among youth subcultures such as punk and emo. It is often associated with a rebellious or edgy aesthetic, and many people choose to customize their spikes with different colors or patterns for a unique look.
