This is Pantene commercial hair. You know—the impossibly glossy and super-straight hair that those shampoo models have, which I always suspect is digitally enhanced. Here it is in real life—and whatever Sandra's using to get this look, I want IN. (I suspect there was, at minimum, some smoothing shampoo and conditioner, plus styling products to straighten and provide heat protection from the flat iron.)

The tucked-behind-one-ear style is actually a variation on a style we saw on <a href="http://www.oscar.com/redcarpet/?pn=gallerybyyear&amp;g=1&amp;i=70" target="_blank">Gwyneth Paltrow at the 2007 Oscars</a> (remember that blush-toned Zac Posen gown?). Loved it then, love it now.
