From the very beginning these two weren't afraid to play around with styles.
The '90s were an interesting but adorable time.
But the year 2000 called for an edgier look.
Even when they rocked identical guitars, hair style could be used to set them apart.
Sara wanted to see if blondes had more fun.
Some highlights were experimented with in 2001.
Moving forward with harsh asymmetrical styles in 2004, the pair was back to brunette.
In 2007 they introduced the mullet that would change everything.
Note the subtle differences in side burn style. Touché ladies.
Everyone wanted to impersonate the look.
In 2008 the duo tackled ponytails...
...and battled against bangs.
Which led to the perfection of the hair swoosh technique you see today.
Who knew there were so many variations on the mullet style?
Like the subtle wispy mullet:
They proved to the world that mullets could be absolutely adorable.
The twins tried out close-cut bobs for their album "Sainthood" in 2009.
Pompadours also made a temporary appearance.
They rocked the Justin Bieber look before he was even on the scene.
Tegan's hair moved in the curly and textured direction in 2010.
While Sara got some inspiration for a new style watching Demi Moore in "Ghost".
Tegan can only part her hair in one direction, but Sara often changes it up.
Tegan experimented with long hair in 2011, while Sara kept it short.
Which brings us to their current hair perfection.
They certainly aren't afraid to think outside the box.
Sometimes they have the same haircut...
...sometimes they switch it up.
But they are ALWAYS perfect.
