Hair metal, also known as glam metal, is a subgenre of rock music that emerged in the late 1970s and became popular in the 1980s. Characterized by its catchy melodies, flashy guitar solos, and an emphasis on image, hair metal bands often sported big hairstyles, tight clothing, and makeup. This style was heavily influenced by earlier glam rock artists and the hard rock sound of the time. Prominent bands in the hair metal scene include Mötley Crüe, Poison, and Bon Jovi. The genre gained significant popularity through music videos on channels like MTV, which showcased the extravagant lifestyles and performances of these bands. Hair metal's appeal began to decline in the early 1990s with the rise of grunge and alternative rock.
