If we are thinking of the bands that came around 1987-91 and were what most people think of as hair metal **
Then it is mostly superstrats with floyds
Kramers
Hamers
Charvel
Jackson
Larrivee
ESP
** It's interesting as fans who grew up with a lot of the bands that later get grouped into "Hair Metal", never saw their bands as that , and often felt the term was very derogatory and insulting.
Van Halen were not hair metal - they came from the 70s
Whitesnake also hailed from the 70s but were restyled for the benefit of MTV and selling mllions of albums
Motley Crue , Ratt, Wasp, Dokken, Black N Blue, Keel, Teeze, Great White , Y&T , Lizzy Borden , Kix also weren't hair metal - some were just considered glam rock, others just rock.
Some were guilty of bowing to pressure from the record companies to jump on the bandwagon and dress a different way to get more MTV airplay
I never saw Bon Jovi or Cinderella as Hair Metal but the lines started to get blurred - Cinderella stayed true to their roots whilst Bon Jovi went very corporate to make millions
I guess the 2nd wave of bands like Poison, Warrant, Bulletboys, Britny Fox, Every Mothers Nightmare, Danger Danger, Enuf Znuff, White Lion, Skid Row , Vain etc were considered Hair Metal
