Marilyn Monroe and Lauren Bacall showed off one of the era's hottest looks as they make their way down the red carpet on either side of Humphrey Bogart: Finger waves.

Audrey Hepburn didn't invent the pixie cut, but she sure brought it to the mainstream. Here she stands out among a see of Marcel waves with her slicked back, spiky crop.

Just because you had a short crop didn't mean you had a flat-laying one like Hepburn. Here Dorothy Dandridge arrives at the 1955 Oscars with a head full of short but showstopping curls.

She was and is a total queen, so it's only natural that at one point or another, Taylor would wear a crown to prove it.

While it might have seemed like the majority of the screen sirens had their hair done up into shoulder-brushing curls, a lot of actresses really committed to the short chop. Here is Miyoshi Umecki winning her Oscar in '58 with feathery bangs, becoming the first Asian actress to win the award.

The star's adorable bob at the 1965 Oscars looked perfect with her glamorous fur — and Warren Beatty by her side doesn't hurt, either.

Native American activist Sacheen Littlefeather is shown here with middle parted, straight hair that is infamous for the 1970s, but she came to the awards ceremony to reject Marlon Brando’s Oscar for him as a stand against how American Indians are treated by the film industry.

Farrah Fawcett brought out the feathered, bouncy goodness on the red carpet that was going to pave the way for the giant, helmet hair of the Dynasty decade.

Michael Jackson walked the red carpet with his perfectly oiled and coiled Jheri curls, and looked fly doing it.

Morgan Fairchild sums up the hair trend of the '80s perfectly: The bigger, the better.

From the choppy bangs to the daisies that appeared on just about every babydoll dress ever manufactured, Drew Barrymore's flirty bob is perfectly '90s.

This Halle Berry haircut (which walked the red carpet in 2002) was so iconic that even my Slavic, immigrant mother requested it at one point.

From 2014 to present day, we've seen more and more black actresses rock their natural hair, just like Lupita Nyong'o and her headbanded coif.

Hathaway won Best Actress for Les Miserables in 2013, but her surprising, tousled short hair really stole the show.

If celebs didn't want to go the polished and straightened route, then many of them opted to tip their hats back to the '20s and '50s with finger waves, Old Hollywood curls, and Marcel dents. Not that any of us are complaining — it looks amazing.

Seeing how hair dos have ran the gauntlet in the past, it's definitely intriguing to think about what this year's trends will be. Timeless, trendy, or all-around unique — hair is one of the most interesting things happening on the Oscars red carpet.
