HER HAIR STYLIST: ANDRE WALKER

From her big, blown-out '80s do to bangs, a bob, ringlets and braids, Oprah has entrusted her hair to one man: Andre Walker, who has worked with the talk-show queen for 25 years. "That's why I still have my hair," she says. In turn, Oprah has named Walker's hair-care line one of her Favorite Things and let her longtime confidant make over her Santa Barbara, Calif., guesthouse, which she then featured in an issue of O at Home and on her show in 2006.
