Aside from catapulting his physique into a demigod-like status, 28-year-old actor Zac Efron, once better known as the cute teenager in High School Musical, also recently chose to switch up a major part of his look: his ‘do.

Earlier this month, Efron took to Twitter to share a new image of himself in which he flaunted freshly dyed blonde locks, but what exactly called for the change? We caught up with the hunk at the L.A. premiere of his latest flick, Mike and Dave Need Wedding Dates, on Wednesday, where he dished on his hair plus how he maintains his toned body.

“I would love to gain 30 pounds and play an aging rock star. That’d be an awesome transformation,” he told reporters on the red carpet, adding, “Otherwise I’m just going to stay mentally and like healthy-fit.” For Efron, doing so seems easy: “I try and get my heart rate up every day. So it depends … today I trained with a trainer,” he told InStyle.

Muscles aside, Efron revealed the no-fuss reason for his hair change in one word. “Baywatch,” he said.

Now you know.
