Shailene Woodley's Changing Looks

The fresh-faced young star, pictured here at age 15, began her acting career at age 4 with small roles in TV.

Going for a more sophisticated look, the Secret Life of the American Teenager actress paired a voluminous updo with a subtle smoky eye at the 2008 American Music Awards.

Woodley complemented her long, side-swept bangs with sun-kissed highlights and a layered cut for the ABC Summer Press Tour Party.

Barely-there makeup and a defined middle part let her natural beauty shine through.

Woodley went for a simple surfer-girl look with natural makeup and a tousled fishtail braid to attend the 2010 MTV Movie Awards.

Later that year, Woodley went back to her natural darker hue, styling her hair in voluminous waves for the annual Teen Vogue Young Hollywood Party.

For the Los Angeles premiere of The Descendents, Woodley piled her hair into a chic but messy updo and kept her makeup natural.

Subtlety defined eyes and a light pink lip offset her messy fishtail braid at the 21st Annual Gotham Independent Film Awards in New York City.

Woodley went glam for the 84th Annual Academy Awards with a bronze smoky eye and a sleek updo.

The actress sported an undone look with face-framing loose waves for the 2012 MTV Movie Awards.

Woodley sported golden blonde locks, which she dyed to take on the role of Tris Prior in Divergent, at Summit Entertainment's Comic-Con event.

After shearing off her hair to play Hazel in the upcoming film The Fault in Our Stars (and donating her locks to the charity Children With Hair Loss), Woodley showed how chic a short 'do can be by slicking back her strands.

For the premiere of her movie White Bird In A Blizzard at the Sundance Film Festival, Woodley let her bright red lip do the talking, keeping the rest of her makeup simple.

Woodley lightened up her cropped cut with honey highlights while promoting The Fault in Our Stars.
