Once a heartthrob, always a heartthrob – at least, that’s the case for John Stamos!

The Full House star took to Instagram to share a throwback Thursday that goes way, way back – all the way back to his high school prom.

Stamos, 52, kept the caption nice and simple: “#TBT #Prom #Hair.”

Indeed, the actor’s long, blown-out ‘do truly steals the show in the hilarious picture of him holding his date in perfect prom stance, decked out in all white with a tuxedo, bowtie and ruffled button-down with red detailing to match the corsage pinned to his lapel.

Stamos has had a busy year between filming Fuller House, the much-anticipated reboot of the beloved ’90s sitcom, and starring in Fox’s new comedy, Grandfathered.

Stamos, who entered a 30-day substance abuse program this summer after being arrested for driving under the influence in June, was sentenced to three years of probation for the charge on Tuesday.

“I’ve had a rough year with my mom dying, so it all came to a head, and it was a turning point,” Stamos told Details magazine in their October issue. “You either continue on that path – and some of it’s fun, but a lot of it’s not – or there’s this other thing, this golden opportunity sitting there with all this work and all this goodwill that you have going for you. That’s the key.”
