Via The Insider:

Zac Efron isn’t sure why people like his hairstyle enough to copy it. He revealed his dirty secret:

“Someone said to me that guys are trying to copy my hairstyle, but to be honest, this hairstyle is derived from laziness. I wake up and go – that’s it. There’s no product in it, nothing. If you really want your hair to look good, just don’t wash for a day. That’s my secret.”

He also told TOTP magazine:

“On a normal day, I’m usually out of the shower and ready to go in a couple of minutes. I’m not a naturally groomed guy. I like to look good, but I don’t get obsessed about it.”

We’re not so sure why people want to recreate his hairstyle either because he always looks a mess. It’s no surprise that he doesn’t wash his hair too often because his hair often looks greasy. Ew.
