Wondering how to convert your favourite beach waves hairstyle into something smooth and sleek this Spring? Look to Olivia Wilde for inspiration. At the Rush premiere in London, the actress wore defined, glossy waves that were more sophisticated than tousled. There are multiple ways to re-create the look at home. First, prep the hair with a heat-safe hair spray like Living Proof Flex (for a similar look try Living Proof Flexible Hairspray, $39) to make sure your hair is protected and to keep curls defined.
Then wrap one-inch sections around a clampless curling iron like the Cloud Nine Wand ($279). You can also use a flat iron to get the almost zig-zag pattern. Gently run your fingers or a wide-tooth comb through the curls to erase any separation between sections. Avoid the brush to maintain the most definition. Finish off the look with more hair spray and a touch of shine serum for that smooth shine on the ends. You can also take another note from Olivia's red carpet look and wear red lipstick for a hint of vintage glamour.
