If you've been wearing the same haircut and hairstyle for a while, it's time to freshen up and do something different with your look, don't you think? Hair should never be boring. As Jo Robertson from GHD hair straightener famously said, "Your hair's the ball gown that you never take off."

So, naturally, you want your mane to be sophisticated and gorgeous in order to show off your best self. For some serious inspiration on what to do with your hair this season, just check out what popular celebrities are doing with their manes. "I think I'll change my hair" is one of the most common sentences they've been known to say on a regular basis, and there have been many crazy hair transformations in Hollywood this year alone.

From Kate Hudson, who went from flowing locks to a straight-up pixie cut, to Julianne Hough, who traded in her long blonde hair for red flowing locks (that are super hot this season, by the way), here are 25 of the most popular celebrity hairstyles that are making waves, if you'll pardon the pun. They'll also make you book an appointment with your hairstylist after you're done reading this article.

25 Kate Hudson's Pixie Cut

How shocking and thrilling to see actress Kate Hudson cut off her long, flowing locks for a racier pixie cut!

Not only does this style highlight her facial features, such as her defined cheekbones and pretty eyes, but it's become a big trend to be more daring with a shorter 'do.

The bonus of cropped hair is that it makes doing your hair in the morning so much easier, so you can focus on more important things, like taking selfies with your friends.

24 Katy Perry's Cropped Hair With 'Tude

Another cropped haircut can be seen on Katy Perry. She's always doing trendy things with her hair, but this hairstyle is one of the most talked about because it gives her appearance an edge.

Her platinum pixie is so stylish it hurts, but it's so much more than just about her hair. As she told Byrdie, "I don’t think that 'sexiness' and 'femininity' is just one thing—long hair. I suppose the goal is to redefine what femininity means to me." Nice!

23 Julianne Hough's Red Flowing Locks

Actress Julianne Hough's signature blonde hair has been traded in for darker, fierier red locks - and she looks just as gorgeous!

Tones of red are heating up hair trends, with everything from auburn, cherry, and copper colors steering people away from their blonde or brown hair.

It's easy to see why. There's a red shade to flatter everyone! As reported by Glamour, red shades like auburn and copper are specifically being requested of stylists - and they're some of the hottest shades to be seen in this year.

22 Emma Roberts' Blonde Lob With Dark Roots

Lobs are big news. Emma Roberts looks fantastic with her buttery blonde hair in this picture, while her dark roots are another big trend to try. Everyone's making their roots more visible, and honestly, it's refreshing.

While it used to be frowned upon for roots to show that one hadn't touched up their hair color in a while, now the more contrast between the hair and root color, the trendier! It certainly helps to have big names like Emma Roberts rocking the trend.

21 Cate Blanchett's Tousled Bob

On the subject of lobs, what makes them so great is that you can wear them in so many different ways. One of the most beautiful styles is to copy Cate Blanchett's wavy, tousled lob.

It looks edgy and fun while still being stylish enough to wear to a glamorous function.

The soft waves and bends in her hair create a softening effect, and best of all it doesn't have to be perfectly curled with a heated iron to be gorgeous.

20 Rihanna's High Ponytail

Rihanna's always rocking a stunning hair trend, and this high ponytail is one of the latest ones. Ponytails have become very stylish, with lots of new ways to jump on the trend without feeling like a schoolgirl again or that they're too casual to wear outside of the house.

Setting the ponytail higher up creates beautiful volume while styling the ponytail length means you still have a hairstyle to put on display, such as by curling it to achieve Rihanna's chic 'do.

19 Mila Kunis' Angled Lob

Another hot lob idea is to choose the angled lob like Mila Kunis. Her hairstyle has been seen everywhere because it's so chic and stylish, whether it's worn sleek and straight or wavy.

As reported by Marie Claire, what makes the hairstyle so fabulous is that it's got a choppy angle and bright auburn highlights to give it extra personality.

Best of all, the lob looks best when it's not over-styled, as Lauren Conrad (another proud lob wearer) points out on her website, LaurenConrad.com. 

18 Demi Lovato's Oversized Braid

We've been seeing lots of mermaid colors in hairstyles lately, as well as attention to the humble braid. Combining the two is an easy way to stay on trend while having an interesting hairstyle you can pretty much wear anywhere.

The bold color takes a plain braid to a higher level of style. The important thing is to make the braid as wide as possible so that it looks like a mermaid's tail, as it does on Demi. Whether you swing it over your shoulder or wear it down your back, it looks beautiful.

17 Gigi Hadid's Middle Parting

Gigi Hadid's middle parting hairstyle suits her so much.

It's a clever way to make the flowing waves of her hair fall beautifully over her shoulders while also framing her face.

Wearing your hair with a straight middle parting requires a clever tip, though, as mentioned on Style Caster: to make it look natural and prevent your hair from fighting back (such as if you've worn your hair in a different parting for a while), part your hair with a rattail comb when it's wet.

16 Ruby Rose's Long Pixie Cut

The pixie cut is always gorgeous, but you don't have to keep it super-short if you don't want to. That's why Ruby Rose's stunning cut is so trendy. With longer pieces in the front, this style gives you much more room to explore different hairstyles, play around with hair accessories (which are especially great for growing out your hair with style), or opt for an asymmetrical haircut. There are many ways to wear the longer pixie cut. Who said short hair was boring?

15 Nina Dobrev's Curtain Bangs

Bangs are in! Instagram recently went crazy over actress Nina Dobrev's curtain bangs. As reported by Elite Daily, her hairstyle looked shaggier and bouncier than ever before, and her bangs effortlessly fell to the sides of her face.

This gave her a fringe that looked chic and effortless, which is what bangs should be like, especially if you don't want to waste hours trying to style them just right.

Keeping the rest of her hair tousled makes the overall look so stylish. This hairstyle is going to be a winner for a long time.

14 Emma Watson's Baby Bangs

Another type of bangs that we're seeing is the baby bang as spotted on Emma Watson. A super-short, choppy fringe looks fantastic on her! It's supposed to look a little uneven, as mixing up shorter and longer pieces of the fringe gives the hair more dimension.

Although it can be scary to imagine cutting off your hair into such short bangs that you can't really do much with until they grow out, be bold. Bangs are a great way to open up your face, as reported by Allure.

13 Kim Kardashian's Soft Curls

Can Kim Kardashian ever do anything wrong when it comes to her hair? Okay, so she recently regretted chopping off her long locks, and we have to agree these long waves are a winner.

Let's be honest: Kim K's long look is a classic that you can never go wrong with when wearing.

The important thing, however, is to keep your hair as healthy as possible and nourished from root to tip so that the soft curls remain flawless rather than frizzy.

12 Lucy Hale's Glass Hair

Glass hair is a current Hollywood hair trend, and as its name suggests, it's when hair is so glossy that it looks like it's made of glass. But, it also requires that hair is cut into a blunt-cut bob and styled by with a hairdryer.

Loads of celebs, including Lucy Hale, have been jumping on the bandwagon, such as Jenna Dewan and Kim Kardashian, as reported by Her. Glass hair is painfully stylish while being a classic that always looks good, no matter the season.

11 Jourdan Dunn's Bob With Messy Bends

Tousled bobs and lobs are always pretty, making you think of hitting the beach or rocking a fashion runway looking like you just rolled out of bed.

But a nice spin on that look is model Jourdan Dunn's bob with messy bends in it.

It basically looks like her hair has kinks in it. The hair doesn't sit in a sleek, perfectly straight style - it sticks up in some places, without looking slept on. The point is to have pieces of different lengths and not be afraid to let them stand out so that you gain va-va-volume!

10 Jenna Dewan's Textured Lob

Jenna Dewan's textured lob is a softer look than Jourdan's, and it's been such a hot trend for a while now. With its gentle waves, the textured lob is flattering on everyone while being chic. It's not always easy for your curls to stay in place, though, so a good tip is to use pin curls.

As celebrity hairstylist Jenny Cho tells Style Caster, after curling your hair, you should roll each section up and use pins to keep it in place. Let the curls cool for 15 minutes, then take out the pins and shake out your curls.

9 Hailey Baldwin's Headband

Hair accessories are having a big moment, and one of the hottest ones to get your hands on is a headband. As seen on model and TV personality Hailey Baldwin, a humble headband can be used to give an otherwise plain hairstyle a bit of character and more volume.

Whether you choose a floral, velvet, or metal headband, it's an easy way to clinch some style without having to do much to your tresses.

If you regularly wear your hair in the same way, a headband gives you a nice style upgrade without being expensive or requiring a trip to the hair salon.

8 Lily Aldridge's Low Bun

Buns have been increasing in popularity for a while now, with messy topknots being a firm favorite. But the humble low bun is back, thanks to the effortless class that it exudes. As reported by Vogue, wearing a classic bun is just one way to nail the trend.

Besides her sleek and neat bun, model Lily Aldridge has been seen wearing a low bun with the tips of her hair sticking out of it, while other celebs have also experimented with different looks. Kendall Jenner, for instance, has been seen with wet-look gelled buns. There are a million different ways to wear them!

7 Jennifer Lopez's Slicked-Back Hair

When Jennifer Lopez wore slicked-back hair to the 2018 Met Gala, heads turned her way. There's no doubt Jennifer's always been stylish, and it wasn't just her gorgeous dress that caught everyone's attention.

Her sleek lob was styled back so that it was both glossy and fresh, with the tips gently curled outwards.

The look was achieved with more than just a good cut - products such as volume-building mousse, hair gel, and hairspray helped to lock it in place, according to Allure.

6 Emma Stone's Hairpins

Another hot accessory to wear is hairpins. As can be seen on Emma Stone, they're a fun way to bring more attention to your hair while pinning it in place. Pretty and practical! To make them feel less like the pins you wore in your teens, use pins in different colors and apply them in patterns, such as by crossing one pin over another or placing one across three pins. Remember to choose a pin in a color that's different to your hair color so that they really shine- you want them to be noticeable.

5 Shay Mitchell's Super-Long Hair

With so many short hairstyles that are making waves at the moment, it's refreshing to see really long hair on Shay Mitchell.

While wearing long hair sleek and straight is a stylish option, letting your hair cascade over your shoulders and back in a more casual, wavy style is trendy right now, too.

It also gives your hair much more body. Make sure to get your hands on a shine spray so that you keep the look beautiful and touchable.

4 Olivia Munn's Bouncy Curls

Having a lob doesn't mean that you only have to have tousled, messy curls, or a sleek cut. You can go out there with big, bouncy curls, just like Olivia Munn. Parting the hair to the side prevents the curls from looking boxy around the middle, while the spray of caramel highlights on her dark locks creates a beautiful sparkling touch to the overall look.

The point is to go big and bold with your curls without letting the length stop you from having fun.

3 Rosie Huntington-Whiteley's Layers

Layers are always trendy and they work with lots of different hairstyles to add dimension and turn up the volume. Model Rosie Huntington-Whiteley had her trademark long blonde locks cut into a shorter, more layered style. This frames her face while also giving her hair greater movement.

As reported by All Things Hair, the layers create body and texture.

Interestingly, this haircut isn't such a dramatic change from her longer hair, but it really adds more bounce and style. It just goes to show how a small tweak to your tresses can make a big difference.

2 Camila Cabello's Parted Fringe

Singer-songwriter Camila Cabello's parted fringe is quite simply darling. What's so nice about it is that it has a bohemian appearance, thanks to its long and loose waves, as reported by Vogue. Don't underestimate the power of a fringe! It can totally transform your look, and it's also youthful.

As reported by Grazia, a fringe is known as the "French facelift" because of how it hides a range of flaws while bringing attention to your eyes. When fringes are fuller in front, they can also make you look younger because they prevent hair from being too thin.

1 Cara Delevingne's Blunt Bob

Recently, model and actress Cara Delevingne sported a freshly cut blunt bob for a Puma campaign. Instead of being spaghetti straight, her hair's got wet-look waves that look fresh and casual.

Grazing her chin, the bold bob draws attention to her facial features, while her blonde waves look beach-ready.

This is definitely a style to try, and it's perfect for those in-between hair lengths whether you're growing out your hair or plucking up the courage to cut it all off.
