According to heavy metal expert Deena Weinstein, down-the-back long hair is the "most crucial distinguishing feature of metal fashion." Originally adopted from the hippie subculture, by the 1980s and 1990s heavy metal hair "symbolised the hate, angst and disenchantment of a generation that seemingly never felt at home," according to journalist Nader Rahman. Long hair gave members of the metal community "the power they needed to rebel against nothing in general."
