According to the dynamic threesome behind RA_Hair House, L.A.'s celeb-frequented hair salon, "short and sexy" is in. However, as celebrity stylist and co-owner of the salon Whitney Colleen points out, summer is all about the Parisian blowout -- which, believe it or not, is way more attainable than it sounds. You can achieve the look by "letting your hair air dry and then going in with a blow-dryer, flat iron, or curling iron and tweaking just a few pieces," says Colleen. The result: model off-duty hair that It girls like Whitney Port, Gigi Hadid and the Olsen twins have made their signature. To create the perfect combination of shine and surf, Colleen recommends Kevin Murphy Hair Resort Spray and a touch of the brand's Shimmer Shine, both available in-salon only.

Scarlett Johansson
Edgy and unexpected, the undercut has been on our radar for some time now. And, thanks to reminders from celebrities like Scarlett Johansson and Evan Rachel Wood, we fall in love with the multi-layered look again and again due to the style's effortless adaptability. If you've been considering a ballsy chop, (but aren't ready for a full-on pixie), consider this sexy-for-summer haircut the ultimate set of training wheels.

Kerry Washington
A summer sans ponytail is like ordering a margarita without the salt -- practically illegal, yes? A seaside savior, this signature tail (be it high or low) can be updated with a side order of thick-cut bangs. Glamorously demonstrated by actress Kerry Washington, the laidback hairstyle delivers drool-worthy drama that still feels cool for summer.

Rachel McAdams
Though this summer will be all about natural, barely touched texture, don't kick your curling iron to the curb just yet. A large-barrel wand is a stylist staple and creates the prettiest of bends when paired with just-above-the-shoulder length, as seen here on Rachel McAdams. According to Blum, ends should be light and carefully textured. To keep the style sleek and polished, use a light-handed dab of hair oil.
Expert tip: Do like the pros and nab the wallet-friendly BabylissPro Nano Titanium Spring Curling Iron, $49.95, which, Blum tells us, is a backstage staple during New York Fashion Week.

Felicity Jones
According to Matrix Celebrity Stylist Nick Stenson, you can dramatically shift your look for summer with the following three ingredients: mid-length cut, flirty fringe and undone texture. We love Felicity Jones' understated, vintage take on a classic summer hairstyle that still feels effortlessly current. If hair is on the finer side, Stenson says to steer clear of thick, heavy bangs, as "this will only take away the length and fullness needed around the face." Instead, get the volume you crave with the help of strategic styling. A skilled stylist will be able to add texture to mimic the look of natural fullness. Matrix Style Link Blowout Big Queen, $16, applied before blow-drying and Matrix Style Link Mineral Airy Builder Dry Texture Foam, $18, applied before curling are a few of Stenson's red-carpet must-haves.
