From 'High School Musical' to Hollywood Heartthrob! See Zac Efron's Changing Looks

Musicals, comedies, dramas -- is there anything this guy can't do? See the actor's changing looks (and successful career path) as he turns 26

It might have been his breakout role in Summerland that hooked you. Or perhaps it was his three-time turn as Troy Bolton in the High School Musical series that made you a fan. If not, you probably jumped on the Zac Efron bandwagon after his starring roles in movies like 17 Again, New Year's Eve or The Lucky One. Regardless of why you're a fan, we can't blame you for loving this Hollywood heartthrob, who turns 26 on Oct. 18. Here's a look at how Zac has changed through the years.

Although Zac's career began with small guest spots (on TV shows like ER and CSI: Miami), his breakout role came on The WB's Summerland, on which he played Nikki's (Kay Panabaker) boyfriend, Cameron Bale. His most successful years were yet to come, but with those baby blues, Zac already had America in the palm of his hand.

It looks like life does imitate art after all: As they approached superstar status, Zac and High School Musical costar Vanessa Hudgens began dating. For the next four years, it was impossible to find a picture of the couple that wasn't adorable.

Age 19

What a difference a haircut can make! In 2006, Zac traded in his trademark shaggy blond 'do for a darker, closer cut. One thing that didn't change: his trademark smirk.

In addition to being a wildly successful movie star, Zac can hardly complain about his costars throughout the years. In 2007, he traded in Hudgens and Ashley Tisdale for Nikki Blonsky, a former Coldstone Creamery employee whose big break came via the leading role in Hairspray. If being an overnight success weren't enough to make us green with envy, working alongside Zac for a year definitely is.

Age 21

Long hair no more! As the High School Musical film trilogy came to a close, Zac's big-screen career really took off. What better way to celebrate a new life chapter than a new haircut? And even though Zac gained a huge fanbase with his long hair, dare we say the short 'do suits him better?

Age 22

Even after their Wildcat days were over, Zac and Vanessa stuck together in front of and behind the camera. Although they ultimately called it quits in 2010, the pair looked as seasoned and glamorous as ever at the 2009 Golden Globes in Beverly Hills.

If there's anyone who can pull off a suit on the red carpet (on par with Ryan Gosling, at least), it's Zac! And he had plenty of red carpets to walk as he grew older, maintaining a healthy career that included one of his most dramatic roles, as the title character in 2010's Charlie St. Cloud.

Age 24

Scroll back up to the top of this page, and the eager 17-year-old you'll find there is barely recognizable! Just seven years later, Zac had matured a remarkable amount, shooting the cameras a smoldering gaze at an N.Y.C. Fashion Week show in 2011.

Age 25

First musicals, then comedies, then dramas... then romantic comedies. Zac took the plunge into the rom-com genre in 2012, opposite Orange Is the New Black's Taylor Schilling in The Lucky One. And while we never would have pegged Zac as the type to slick his hair back, we can't deny how suave he looks at the film's Hollywood premiere.

On his 26th birthday, Zac looks as professional and sexy as ever. Now sporting a short wavy 'do and an even bigger collection of dapper suits, Zac remains one of Hollywood's hottest heartthrobs -- and his phenomenal success isn't too shabby, either.
