Michelle Obama's Changing Looks

Barrettes and a brain: Michelle LaVaughn Robinson attended the gifted program at Chicago's Bryn Mawr Elementary School.

The Whitney Young High School senior (and class salutatorian) wore her hair in a gravity-defying pouf.

Still Michelle Robinson, she showed off her natural curls (and her mortarboard) for her Princeton graduation.

The new Mrs. Barack Obama wore her hair pulled back into a classic chignon for her wedding day.

The hospital administrator (and U.S. senator's wife) tinted her signature body-filled bob a subtle cinnamon shade.

Mrs. Obama got glam for the NAACP Image Awards via a sleek updo and copper shadow.

She hit the presidential campaign trail with a voluminous, face-framing bob.

The new First Lady showed off her cut's versatility with playful waves.

No short crop here! "I'm a big fan of what I call the up-tuck," her hairstylist Johnny Wright told us. "You pin-up all the hair in the back, and then let the front fall naturally. It's like you've gotten a haircut."

Mrs. Obama sported sexy side-swept fringe and eye-catching long lashes.

"I like updos that look very simple and natural," Wright said. "People try to make their hair a little too perfect with updos, and that's where it goes wrong. Honestly, the messier the better." The First Lady looked stunning in a half-updo with loose curls at the nape of her neck.

An evening look doesn't always require an updo! Mrs. Obama looked extra glam with modern, messy ringlets.

A smooth bun was an elegant daytime look for a visit with the King of Spain.

The First Lady dressed up for a state event with a glamorous pompadour, a chic smoky eye and clear gloss.

The First Lady wore her bob in loose curls at a DC event.

Obama chose a sleek look for a meeting of the Hollywood Guild and military families.

A textured updo for BET Honors.

Mrs. Obama was back to silky layers for the Nickelodeon Kids' Choice Awards.

The First Lady debuts sleek bangs to complement her bob.

So many changes, so little time! Obama ditches her bangs for a side part, and opts for ombre tresses.

The first lady kept her hair and makeup simple while attending the Let Girls Learn Global Conversation in New York City.
