The secret to the actress's perfect blonde hair color? Rick Wellman, the Patrick Melville Salon & Spa colorist prepping her for the award season's ultimate evening this year, tells us it's all about a gentle touch. "Highlighting blondes using the Bio-lights method creates dimensional shimmery blonde, as if you were born with it without the risk of over-processing," he explains. The aluminum foil-free highlighting process uses only cotton pads during processing and is far less harsh on hair.
