Baby Olivia Benson before lots of layers.
She means business.
She really means business. Hargitay said this haircut almost got her fired.
The Justin Bieber before Justin Bieber was a thing.
She's looking for the scissors.
This is kind of quintessential Olivia Benson.
Remember this episode where she talked to a girl on the phone the whole time?
Post-baby (in real life), sassy new 'do.
Werkin' that bridge.
Classic later seasons Liv look.
No blunt haircuts here.
The first season without Stabler, Liv let her hair do the talking.
Look at those waves.
After being held captive and tortured, Benson chopped off her hair.
Benson became a sergeant in season 16, you can tell by the "I'm in charge" look on her face.
No more waves, Benson's gone pin-straight and down the middle for season 17.
This isn't your typical mom 'do.
She's sarge and in charge. Not a drastic change to season 18, but there are more choppy angles here.
Sleek and simple. Still similar to her previous seasons look, but with a middle part.
Just a casual windswept moment.
Did we shamelessly use this selfie as a way to work in a Stabler and Benson reunion moment? Why yes, yes we did.
We need the number of Hargitay's hair colorist.
