Here's why Sia hides her face with wigs and bows

Sia may be a musical genius, but what does she look like under that huge bow?

Turns out, really different.

The 40-year-old singer recently performed at the Apple Keynote 2016 event and, as usual, she rocked her blonde and black wig that covered the majority of her face with a whopping white bow perched precariously on top.

Sia sang two songs as her dancer Maddie Ziegler performed off to the side.

Though she's been writing songs and making music for almost two decades, she only recently reached her current level of fame after a 2011 hit with David Guetta. Sia has made it point of hiding her face since she started becoming known in the industry in an effort to be less recognizable.

"I don't want to be famous, or recognizable," she explained to Chris Connelly on Nightline in 2014. "I don't want to be critiqued about the way that I look on the internet. I've been writing pop songs for pop stars now for a couple of years and I've become friends with them and see what their life is like and that's not something I want."

Sia also wrote an op-ed in Billboard about her decision in 2013.

"If anyone besides famous people knew what it was like to be a famous person, they would never want to be famous," Sia wrote in Billboard. "Imagine the stereotypical highly opinionated, completely uninformed mother-in-law character and apply it to every teenager with a computer in the entire world. Then add in all bored people, as well as people whose job it is to report on celebrities. Then, picture that creature, that force, criticizing you for an hour straight once a day, every day, day after day."

However, Sia often attends events without her staple wig, and you'd probably never recognize her sitting in the crowd with her platinum hair piled on top of her head:

Her own wispy blonde bangs aren't so different from the blunt cut of her wig. She also consistently rocks her statement red lipstick.

And she really loves the top bun look.

It's possible Sia's desire to hide her face stems from more than just her fear of the dark side of fame. Sia has been publically open about her past struggles with drug and alcohol addiction as well as depression and bipolar disorder. She even considered suicide in 2010.

Still, whatever the reason, Sia has dozens of blonde or dual colored bob wigs that she wears when she performs around the country. Now, her look is iconic.

"I'm trying to have a good life," she told NPR. "Basically, my plan is to enjoy what I have."
