It's the most wonderful hair time of the year--prom season!

If they're not already, prepare for every Saturday for the next three months to be booked solid with special occasion style appointments, which many stylists will hail as their absolute favorite appointments to take on. Though Pinterest has aided tremendously over the past year to helping clients enter the salon better prepared with photos of the looks they'd like to achieve, stylists still have some prep work to do to steer clients in the right direction with fresh, trendy styles. And this is where MODERN would like to help.

From funky to fabulous, here are 10 memorable celebrity styles that may be of interest to your special occasion clients seeking that standout look for their big night out this spring.

Kate Middleton's Chignon

It's likely your younger clients will forego the hat with this look, but if Kate liked the idea of this updo enough to wear her hair up (a rare occasion), then it's sure to be a winner of a prom style.

Julianne Hough's Pinned Pomp

Prom isn't just about updos--expect some requests from clients for styles with a bit of an edge and be prepared to offer up hair inspiration like this look from Julianne, which is ideal for ladies with locks on the shorter side or in between growth stages.

How-to: Try these tips to recreate Nikki's structured bun, styled by Mara Roszak.

Bella Thorne's Twisted Pinup

Christina Aguilera's Purple-Kissed Tips

Because we figured we'd end this on a particularly colorful note. If your client isn't necessarily seeking a complicated updo or even the super-trendy Hollywood waves, consider color work--temporary or not--to add some punch and complementary style to her down 'do.
