Efron slyly debuted the new look on Instagram, posting a photo of himself rock climbing that showed just the front part of his newly-dyed hair peeking out. You can also see that he's rocking a scruffy beard, which is something we cannot support enough.
The reaction to the news has been decidedly un-chill, with fans extremely on-board with this new look.
Now, this isn't actually the first time Efron's rocked a lighter 'do. For the 2017 cinematic masterpiece Baywatch, he had blonde highlights running through his hair — and he rocked blonde hair the summer before its release, too.
This does appear to be the first time he's dyed his entire head platinum, however, which makes this his most dramatic real-life hair transformation to date. We're sure those locker pictures will be updated shortly.
