These Are Hands Down Ashley Olsen's Best Hair Looks—Because It's Her Birthday

To say Ashley Olsen's hair is iconic would be an understatement—at least for the bevy of blondes growing up in the '90s and early 2000s. She's been my cool-girl wave inspiration for as long as I can remember. So much so that her hairstyles garner thousands of searches on Google each month. "We've been working with Mark [Townsend] since we were 12 or so. It's a great relationship and one that allows us to evolve together," her sister told me when I interviewed them this summer.

So we thought it necessary to round up her most iconic styles to click through (and pin, save, or screenshot) for whenever you need hair inspiration. Behold a comprehensive history of Ashley Olsen's hairstyles.

In 2005, Olsen went platinum blonde with a straight, bouncy updo for a party hosted by Lucky Magazine in L.A.

That same year, Olsen arrived at the ACE Awards in New York City with tighter curls cascading from her '90s-inspired updo.

In 2006, Ashley Olsen attended the Met Gala with a deep side part and wispy front pieces.

Also in 2006, Olsen posed in front of the step-and-repeat for Free Arts NYC's 7th Annual Art + Photography auction benefit. She wore her milkmaid braid with pieces pulled out for an effortless, cool-girl effect.

For the launch of her new apparel line that same year, Olsen showed off big, brushed-out curls with a '70s vibe in Sydney, Australia.

In 2007, Olsen went for a Brigitte Bardot vibe with big, sexy volume and lift at her roots for the reopening of the New Museum in New York City. 

Later that year, she arrived at the Chanel Cruise Show in Santa Monica, California, with an undone updo.

Ashley Olsen arrived at the Sex and the City: The Movie premiere at Radio City Music Hall in 2008 with a slightly edgier, brushed-back style.

In 2009, Mark Townsend cut her iconic hair into a sleek, graduated bob.

In 2013, Olsen wore her hair parted down the middle and slicked back into a low bun at Club Monoco's Fifth Avenue flagship in New York City.

For the Costume Institute Gala that same year, she went au naturel with the bedhead waves we know her for (and can't get enough of).

Ashley Olsen attended the 2014 World of Children Awards sporting her usual middle-part, messy-wave style, only this time it was slightly longer.

In 2015, Ashley Olsen arrived at the China: Through the Looking Glass Met Gala with slightly darker hair and a half-up bun style.
