Ummm...no. By no means am I an AC/DC nutswinger but they were/are in no way shape or form at all similair to hair metal. Not even close. Hanoi Rocks, Poison, Warrant, Winger, Cinderella, Ratt etc were glam or hair metal.
AC/DC falls under the Hard Rock/Metal category. One could argue blues based hard rock not unlike Aerosmith or Led Zep. But hair metal? Nope they didn't have the sound nor the image of it. In fact they got rid of their original frontman because they felt he was to influenced by glam rock.
