Hair metal, also known as glam metal, is a subgenre of heavy metal that emerged in the late 1970s and peaked in the 1980s, primarily in the United States. It’s characterized by its flashy, theatrical style, combining the raw energy of heavy metal with elements of pop rock, punk, and glam rock. The term "hair metal" comes from the bands' signature big, teased hairstyles, often paired with flamboyant clothing, makeup, and a party-hearty aesthetic.
Musically, hair metal features catchy hooks, anthemic choruses, and polished production, emphasizing melodic guitar riffs, shredding solos, and powerful vocals. Lyrics often focus on themes like partying, romance, rebellion, and living the rock 'n' roll lifestyle. Bands like Mötley Crüe, Def Leppard, Poison, Bon Jovi, and Guns N' Roses defined the genre, with albums like Hysteria (Def Leppard) and Appetite for Destruction (Guns N' Roses) becoming iconic.
The genre thrived on MTV, where visually striking music videos showcased the bands’ over-the-top image. Hair metal dominated the charts in the '80s but waned in the early '90s with the rise of grunge and alternative rock, which rejected its excess. Still, it retains a nostalgic fanbase and has influenced modern rock acts. Many consider it a quintessential '80s sound, tied to the era’s hedonistic vibe.
