Def Leppard, Van Halen, Bon Jovi, Guns N Roses, and Metallica are not hair bands
Some are obviously a little closer to that category than others (Def Leppard is the closest), but none of these are really hair bands. My favorite from more of a pure hair band is Here I Go Again by Whitesnake. If you were to count Def Leppard, then Hysteria is my favorite.
