By Katherine Fritz, a Philadelphia costume designer who writes regularly for MTV Style:
As the cold weather creeps in around Philadelphia, it's temping to let the gloom take over and the hibernation set in. It can be hard to feel like your best self with a red nose, icy fingertips, or split ends.
Rather than spending winter in the land of the messy bun, consider boosting your mood with a fresh new hairstyle.
This past year saw the rise and fall of several trends, some of which might quietly disappear -- glitter roots, anyone? -- and some of which are forecasted to stick around for awhile. It's not hard to see, just walking around the streets, how quickly these celebrity looks have influenced current style.
Whether you're curious about how those trends might look beyond the pages of a glossy magazine, or simply want some tips on integrating on-point trends into your everyday look, Solaris is here to help. We scoured the Internet for our favorite hair trends of 2015, from the celebrities to the girls-next-door (er, on Instagram), and can't wait to help you discover your best hair for these cold winter months.
While the "long bob" has been gaining in popularity for years now, it was the unveiling of Kim Kardashian's bold new lob that really broke the #hair #internet this year, with celebs like Julianne Hough, Taylor Swift, and Lucy Hale swiftly joining her ranks.
We love the textured playfulness of this style, and as trends go, we hope this one sticks around.
The piece-by-piece asymmetry gives the look a feeling of effortlessness, and makes even the dreariest winter day feel just a bit like the beach.

This timeless, striking style took on new dimension this year when it made thousands of headlines, otherwise known as the "man bun."
Ladies, don't let the headlines scare you: it's not just a trend for dudes. It's actually the perfect way for those with longer locks to get a high-fashion look with minimal effort, particularly in those cold winter months when it's tempting to hit the snooze button and spend less time with a comb.
Simply sleek your hair into a ponytail positioned at the upper-back of the head, wrap, and secure with an elastic or pins. There's merit and elegance to the sleek, smoothed version sported by Demi Lovato, although we have a secret soft spot for the messier variety that's been cropping up all over Instagram.
The braided hairstyle got a high-profile update this year -- not from a runway or a red carpet, but from a boxing ring.
The explosive popularity of women's MMA (Mixed Martial Arts) fighting and its breakout superstar Ronda Rousey led to women copying her look: feminine yet strong, practical and elegant.
The first female UFC Champion also periodically takes to YouTube to demonstrate how she styles her hair (that is, when she's not leaning on longtime stylist Abraham Esparza); we love that Ronda's identity of "strong, athletic, warrior woman" can also include hair tips.

At the advent of those endless holiday parties, those with shorter hair might find it hard to keep their options open.
Despite chopping her hair into a shoulder-length bob several weeks ago, Jennifer Lawrence has been attending Hunger Games premieres with a seemingly endless variety of chignons, slicked '60's inspired waves, and this effervescent princess look. How? With just enough hair to turn under, the braided updo is possible for most medium-length haircuts, giving the illusion that more length exists.
The pieced-together whimsy is a perfect pairing for a dressier formal event; holiday office party, perhaps?

This year's fashion trends saw menswear repurposed as womenswear: suspenders, hats, combat boots, and harem pants all made big reappearances on the scene, in reinvented, mainstream ways.
It's no surprise, then, that the undercut has been adopted from a traditional man's haircut (think 1920's-era "Peaky Blinders") into a bold look for men and women both.
It's extreme, and not for the faint of heart: one or both sides of the temple areas are cut very short or shaved.When worn down, of course, longer hair conceals the cut -- leaving it up to you how to best feature your secret punk neckline.
Some ladies are even asking their stylists to shave patterns into the hair, leaving plenty of opportunity for creative experimentation.
If you're taking your cues from icons like Miley Cyrus or Scarlett Johannsson, we say: be bold, live free, and shave it off!
This past year might as well be dubbed The Year of the Headband: from Ariana Grande's signature cat-eared look, to the thousands of free-spirited women rocking bold flower crowns all summer.
The look can be minimized to accommodate winter needs too, and a metallic headband is often the perfect accessory to complement any formal or work-related winter event.
While the headband alone does most of the job itself -- just brush hair, add headband, and go! -- an easy way to add extra elegance with minimal effort is to incorporate it into a more complex style.
These classical-Greek inspired updos pair perfectly with the right simple headband: from the more flashy pearl or rhinestone pieces to the thinner, shiny elastic variety, to the metal-and-gemstone variety.

Elegance-on-the-go, with a nod to the swinging sixties, this look is the perfect thing for when you want to test out your skills with a liquid liner, or simply transition from the workplace to the evening with a fairly easy-to-navigate step.
It doesn't hurt that it's the favorite look of celebs from Beyonce to Ariana Grande, and it's a perfect showcase for dangly, chandelier earrings that add a little sparkle this time of year.

On those days when you want to show off your mermaid-like length, but don't want to brush it out of your face continually (and who does?), look no farther than real-life Princess and elegant icon Kate Middleton.
Her half-up twist lends a degree of formal elegance to her lengthy locks that's way above a ponytail holder or some bobby pins, yet isn't so complex that it takes too long, or seems overly fussy.
It's a trend that resurfaces every so often in slightly new ways, and for a good reason: it straddles the gap between updo and casual, and its simple charm never goes out of style.
