For the Emmys in 2009, Byrne rocked a sleek lob with golden highlights. Her hair was matched with a paired-back makeup look, consisting of rosy cheeks and a subtle smoky eye.
At the Get Him to the Greek premiere in 2010, she opted for voluminous, brushed-out waves and repeated her trusted makeup look - a natural face with dark eyes.
Bryne coordinated her bright lips with her dress and offset the look with bright pink eyeshadow. Her tight curls and pinned back fringe set all the attention on her makeup.
In 2012, updated her hairstyle with a shorter fringe and mid-length bob. This classy look was rounded out with rosy cheeks, pink lips and dark eye makeup.
Bryne swapped the shorter fringe for full, rounded bangs and a tight bob. This time opting for different eye makeup, the highlights in her hair matched with her golden eye shadow.
Beginning to experiment with her beauty look, Byrne went for neon pink lipstick, silvery eyes and bright blush; all to bring out the colours in her dress. She styled her hair in finger wave curls and swapped her bangs for a parted side fringe.
Byrne's go-to beauty look of a simple face and a smoky eye seems new and refreshed here, with her hair sleek and tucked back.
Glossy red lips and elegant waves set the tone for Byrne's beauty look at the 2016 Tony Awards. Her bold lip colour was paired with pink glitter around the eyes.
Byrne shocked the world when she debuted her platinum blonde hair at the premiere of Broadway play The Lifespan of a Fact. In a major transformation, Byrne ditched her iconic brunette hair colour for a bleached blonde look.
Still rocking blonde locks, Byrne softened her hair colour by adding in some honey yellow tones. Her pretty makeup look consisted of pink lips, minimal blush and eyeshadow and strong eyebrows to contrast her blonde hairstyle.
