Our Celebrity Hair Look of the Week goes to British singer/songwriter Leona Lewis. Pictured at the annual Rockefeller Christmas Tree lighting at Rockefeller Center in NYC sporting her famous voluminous curls. What we love about this look is the amazing texture and color. Its what I like to call Winter Blonde, not to bright but with just enough glow to brighten up her look and the dark roots really adds dimension to the look . The curls have great texture not at all frizzy but not to stiff and perfect. Her hair looks soft and touchable! Lovely! Check out more pictures below!
