R.I.P. to the victims of the Great White concert tragedy.
Aerosmith is not a hair band.
Van Halen is not a hair band.
Bon Jovi is borderline, but I wouldn't call them a hair band.
Part of being a hair band is being not very good, largely forgettable outside the 80s and their one or two big songs. Also, there's a difference in the type of rock they play. It has to be 100% 80s.
they were a band, they had hairs, they had a song with that title
Hair + Band = Nelson
