Michelle wore her light blonde pixie 'do cool and casual to the 84th Annual Academy Awards. She has gone peroxide blonde here. The solid buttery color isn't as flattering to her face or the cut as the more natural looking blonde shades, but pixie cuts do look more edgy with bold, monotone colors. The back and sides are tapered into the head with the edges chopped and sliced to achieve a light and wispy finish all over. This low-fuss hairdo is easy to maintain with regular trims every 4-6 weeks.
