Michelle Obama has only been the first lady for a few weeks, but her chic head-to-toe style is already inspiring millions! And when it comes to her hair, it's always about the right style for the right event. The man who's been her hairstylist for more than 25 years, Rahni Flowers, explains his approach for his now-famous client.

"She has a very active life," he says. "She works out a lot, she's got two wonderful children, she has a job, and she's a wife. She needs a hairdo that functions and works with her. In a collaborative effort, we work to get the look that will work with her lifestyle." And since Rahni isn't always around, he also gives Michelle specific instructions on how to achieve that look herself.

With Rahni's Van Cleef Hair Studio in Chicago and the Obama family now in the White House, Rachael asks if he will continue to work with her. "It would not be a very pragmatic thing to fly me back and forth to Washington D.C. in light of the economic climate in the United States," he says. "What we agreed to do is I would help train people who live in D.C. to maintain her look and her schedule -- that would be a lot better."

Rachael, who interviewed Michelle before the election, comments, "She is such a beauty."

Rahni agrees, "She is -- inside and out."
