I have 80's hair even now! For me it never went out nor flat for that matter LOL!
I always feel naked without my hair poofed up/out. My husband does tell me though that when my hair is flat my personality is sweet, and when I do my hair up I have an attitude. Hahahaha what???

Only thing that has changed for me would be the hair spray. Now it's Aussie sprunch spray. I refer to it as the new and improved Aqua Net.
Good old Aqua Net= Hair Cement!
