Rooney Mara With Platinum Blonde Will Make You Do A Serious Double Take — PHOTOS

If you thought Taylor Swift going platinum blonde was the hair transformation of the summer, get ready for a complete shock. Adding to the list of celebrities that have picked the light hue this season, Rooney Mara now has platinum blonde hair. The actress went from one extreme to another with this change, but looks pretty darn good in both colors. This isn't the first time she's rocked an unconventional hair look, and I'm guessing it won't be her last.

Mara has always been know for her dark hair, vampy look, and effortlessly cool style. Well, prepare for the world to turn on its head, because the actress has just surprised everyone with her most drastic change yet. The 31-year-old traded in her dark brunette hair for something a bit more summery. And by that, I mean the brightest she could possibly go. It's definitely the star's biggest hair transformation yet, even compared to all her quirky red carpet updos.

Mara isn't the first celebrity to ditch their signature style for platinum blonde recently. Swift, Emma Stone, and even Kim Kardashian have tried out the shade. This is definitely the most drastic of them all, though. Some social media posts infer that she might have gone blonde for her new role in The Discovery, so it'll be interesting to see how long she sticks with the bright color.

Yep, that's a blonde pony sticking out of that beanie! If you think this is good, just wait until you see it down.

You almost can't tell that it's actually her. Here's how it looked before, so you can see the true transformation.

Mara has had plenty of fabulous styles over the years, but this definitely takes the award for most drastic transformation. Let's just hope she keeps up with the awesome updos even though she's going for a new look. Here are some of her best quirky styles yet.

What looks like it might have started off as a half-up, half-down look transformed into something seriously stunning.

If you can believe it, this isn't even her coolest hair look.

The actress slicked back her hair to look like she had bangs, which is pretty fabulous if you ask me.

Not just anyone could pull this off.

Why bother with one ponytail when you could have two?

Although the front was slicked back, the actual ponytail was disheveled, making for a romantic look to match her gown.

Teach me your ways, Mara!

If this isn't walking art, then I don't know what is.

6. Low Braided Bun

She could've just opted for a low bun, but then it wouldn't be a true Mara style.

7. Unconventional Accessories

Just when you think it can't possibly get any better, she adds hair accessories.

I could go on all day about how fabulous this woman's hair is, but you probably get the picture. Let's just hope the gorgeous updos continue with her platinum hue as well.
