Steve Harrington is now the male role model Dustin (Gaten Matarazzo) needs in his life. He’s also his style icon, too: he uses the boy’s secret weapon – Fabergé Farrah Fawcett hairspray – to impress the attendees of the Snow Ball at school.
Let me be pedantic for a moment here: I don’t think the can Dustin is using is the original one. If you look closely, the writing on it is different from the writing on the original can. So they took the writing of the non-aerosol version and put it on the aerosol one. Good job!
