Catherine Zeta-Jones doesn't need chemicals to whiten her teeth. She just eats a few strawberries. "The juice or pulp of strawberries contains malic acid which serves as an astringent and can lighten surface stains," she says. "Pineapples work the same way." She also suggests conditioning with honey and beer. "I smell like the bottom of a beer barrel for days afterwards but it's very good for the hair." [Daily Mail]
