A ballerina bun is an office-appropriate summer hairstyle that won't let you down. The gravity-defying, twisted nature of top knots can sometimes be too casual in an office but not the ballerina bun. Keep it chic by avoiding hair-nets of any kind and by smoothing down errant baby hairs. Pro tip: Run an old toothbrush that has been misted with a bit of hairspray over front layers for a sleek finish.

Keep strands off your hot neck by parting hair down the center and gathering the ends into a loose twist. Gently encourage shorter pieces to come out so they can frame the face. Pair the hairstyle with a collared shirt and possibly a statement necklace and you've mastered summer work style.

Whether hair is long, short or in a lob, a brushed-back hairstyle is a great summer work option because it's easy and appropriate. The key is getting the finish right. Leave gel off and use a non-crispy hairspray to keep strands in place. Moroccanoil Luminous Hairspray Strong, $24, is a weightless, non-flaky formula that doesn't leave behind a sticky residue. It also repels humidity and fights frizz.

Even if you're not at the beach, the warm weather can dry out hair and leave it prone to frizz. A protective hairstyle will provide a cooler finish than a blanket of hair. Part tresses in the center and braid a few thick cornrows on either side. If hair is long, twist the ends into a low bun for optimal neck coolness.

Plagued by oily front layers that look and feel greasy even if they were just washed hours ago? Survive the eight-hour (or more) workday with a sleek half updo. Part the layers on the top of the head to form a thick section that spans the distance between brow arches. Pin strands at the back of the head with bobby pins or a pretty barrette. Leave the rest of the hair loose. The look works whether hair is straight, curly or somewhere in between.
