Salma Hayek, Katie Holmes, and Kristen Wiig have been keeping their hairstylists busy this week! Hayek unveiled tawny copper highlights at an event in Paris, while Wiig arrived at the New York City premiere of Anchorman 2 in a deep auburn hue. Both stars are no strangers to shifting shades — experimenting with dark brunette colors, ombre highlights, and many trends in between — and their current looks are especially flattering against each of their complexions. Holmes, on the other hand, took her lengthy strands to a shoulder-skimming cut. The style isn’t as dramatic as the bob with bangs she sported back in 2008, but we think it’s gorgeous all the same, especially since the actress prefers to keep her hair on the longer side these days. “At the time, I wanted something much easier,” she previously told us of the ultra-short crop. “I like my hair long for now, but that might change!”
