20 Celebs Who Aren't Afraid To Get Bold With Their Hair Color (& 5 Who Shouldn't Experiment)

We absolutely love celebrities who are fearless when it comes to experimenting with their look. After all, they usually have an extremely talented team of experts who can help bring any vision to life - why not have fun with things?

Of course, there are often restrictions in Hollywood. For example, if an actor or actress is playing a particular character with a particular look, especially for an extended period of time on a television show, they often have limitations when it comes to what they can do to their look. However, once they're given the freedom to mix it up, many do - especially if they've been stuck with their character's look for years on end!

From vibrant, bold colors to eye-catching pastels, from pinks to blues to greens, celebrities have dyed their hair just about every shade under the sun - and so many of them look absolutely amazing with the end result! It just proves that you should never be afraid to take a beauty risk.

Here are 20 celebs who weren't afraid to get bold with their hair color and pick something definitely not on the neutral end of the spectrum, and 5 celebrities who perhaps missed the mark when it came to their transformation.

20 Celebs Who Aren't Afraid To Go Bold With Their Hair Color:

25 Dascha Polanco's Ice Grey Locks That Are Majorly Chic

Obviously, while she's filming Orange Is The New Black, Polanco can't get too crazy with her hair color - after all, there's not a lot of hair dye options in prison. However, in her time between seasons, she decided to mix things up and trade in her brown locks for an icy grey shade. It looks absolutely gorgeous on her - and though she had to dye it back for another season of filming, we're really hoping she returns to it soon! It's super glam and totally gorgeous.

24 Kylie Jenner's Fuchsia Locks, Proving That She Still Has Major Style As A Mom

Kylie Jenner is a bit more open to mixing up her hair color than other celebrities because she so often does it with a wig rather than by actually dyeing her hair. However, we have to hand it to her - the woman is utterly fearless when it comes to trying out new shades. And, somehow, they all manage to look utterly amazing on her. This pink shade would look super fake on many celebs, or wash them out, but on her, it looks fun, flirty, and super chic.

23 Gigi Hadid's Flirty Pink Ponytail

As a model, Gigi Hadid is used to having to change her look for shoots or runway shows - and we love the pink ponytail she was trying out in this look. Rather than dyeing all her strands, she decided to add a few streaks of pink, in a variety of shades, to her regular blonde locks - and the result is beautiful. It just goes to show that there are so many ways to incorporate color into your look - you don't necessarily have to dye all your hair one bold shade if that's not your style.

22 Alicia Keys' Bold Orange And Pink Braids

Alicia Keys has rocked a lot of hair looks over the years, but we have to admit - we have a soft spot for when she rocks braids. There's just something about them that looks so gorgeous on her. And, while her normal hair color is amazing, we love that she wasn't afraid to go bold with her braids and incorporate shades of neon orange, yellow and pink. It's definitely not a look for everyone, but she totally pulls it off in style.

21 Ruby Rose's Vibrant Pink Hair That Totally Matches Her Name

With a name like Ruby Rose, it's only a matter of time before you dye your hair pink or red - and this gorgeous actress definitely didn't disappoint! While she would look amazing with any hair color because, well, she's stunning, there's something about this edgy deep pink that seems like such a perfect fit for her. We're not sure how long she's going to keep this particular shade, but fingers crossed that it's a long-term look for her - we're obsessed with it!

20 Rita Ora's Sassy Pastel Rainbow Ponytail

When it comes to celebrities who experiment with their hair color, Rita Ora is definitely at the top of the list. The British pop star has a super fun, funky sense of style, and that extends to her beauty choices as well as her red carpet looks. We love the contrast between her regular blonde hair at the roots and the cascading shades of color throughout her ponytail. It's done so masterfully and it's a great way to mix up your look without having to commit to a single shade.

19 Hilary Duff's Blue Hair That's Definitely Not So Yesterday

Hilary Duff may be best known for her California girl blonde locks, but that doesn't mean she's unwilling to experiment with different colors - in fact, she seems to absolutely love playing around with her hair color, as this look proves. A while back, she played around with a gorgeous icy blue shade that we can't get enough of. This would be such a great shade for fall/winter too - paired with a deep plum lip like she's rocking here? Flawless and totally fierce.

18 Lena Dunham's Creative Mint-Colored Coiff

When it comes to style, Lena Dunham definitely isn't afraid to march to the beat of her own drum - and that includes her hair color! She decided to trade in her normal brown locks for a minty green color, and we have to admit, it's kind of chic. We'd rather see it without the dark roots, but hey - maintenance can be a bit of a hassle, we get it! We'd love to see her totally mix up her look at some point and go for longer locks again (although the short styles look adorable on her as well).

17 Jemima Kirke's Dreamy, Romantic Pink Highlights

Lena Dunham's former co-star Jemima Kirke has become known for her long, wild, wavy blonde locks, and we don't blame her for wanting to keep those as is. However, we love that she decided to mix it up by adding a splash of pink into the mix. The shades of pale pink mixed in with her gorgeous blonde hair creates an effect that's just breathtaking. And we thought her hair couldn't get any more gorgeous! It just proves how transformative a splash of color can be.

16 Nicole Richie's Super Chic Lavender Look

When it comes to her hair, Nicole Richie has rocked a lot of looks - and luckily, her more recent choices are a lot chicer than the styles she favored back in the day. She's dyed her hair just about every color imaginable, but one of our favorites is definitely this lavender look. The length is elegant yet flirty, the shade looks absolutely gorgeous with her hazel eyes, and the whole look just totally works for her. We love this one.

15 Azealia Banks' Seaweed Green Mermaid Waves

Azealia Banks isn't afraid to speak her mind, so it probably comes as no surprise that she also isn't afraid to mix up her hair color and go a little bit bolder. She decided to go green a while back with a super dark, rich seaweed shade that we absolutely love on her. The shade is so deep that it almost looks like a dark brown or black at first glance until you look a little closer and see the true shade. Gorgeous!

14 Rihanna's Rich Red Hair That Was A Total Gamechanger

Okay, we're pretty confident that Rihanna could rock literally any look and look amazing - including this long, fiery red hair vibe she had going for a while. In fact, in comparison to some of her other looks, this one is almost a little tame. However, there's something about the way the shade brings out the warmth in her skin, goes with her deep brown eyes, and pairs so perfectly with a classic red look. This one is definitely a winner!

13 Anna Paquin's Daring Purple And Green Look That We're Super Into

For quite a few years of her life, Anna Paquin played the role of Sookie Stackhouse on the HBO hit True Blood. As such, she couldn't really experiment with her look all that much, because she'd always have to return to Sookie's look. However, once the series wrapped, she celebrated the end of that chapter of her life by dyeing her hair a vibrant shade of purple (with a splash of blue thrown in, just for fun). We totally love the end result.

12 Perrie Edwards' Ombre Pink Look That Is Amazing On Her

We're not sure what on earth Zayn Malik was thinking when he dumped Little Mix band member Perrie Edwards - I mean, the woman is totally gorgeous and insanely talented! She's become known for her platinum blonde locks, but she decided to mix things up a little with a pink ombre look that we're totally into. The fact that she incorporated a darker shade towards the bottoms of her hair and a lighter shade at the roots gave two colors that might be a little flat on their own a ton of dimension.

11 Kylie Jenner's Super Long Peach Locks

Okay, honestly - is there no hair color that Kylie Jenner cannot totally rock? She stepped out a little while back in a pale peach wig that looks absolutely amazing on her - and also proved that she wasn't going to give up her beauty chameleon identity just because she became a mom! She's still planning on mixing up her hair from day to day, and we have to admit, we're totally into the peach - it's a bit softer than what she normally goes for, and a refreshing change of pace.

10 Zayn Malik's Pink Tips That Prove Guys Can Have Fun With Color Too

When Zayn Malik left One Direction and decided to embark on his solo music career, he knew he'd have to stand out from the crowd - and one of the ways he did that was by mixing up his look. One particularly bold look was this one; when he paired the shaved sides with frosted pink tips. It's a bit of a throwback to the frosted tip look that was popular in the '90s but in a way that's modern and updated.

9 Grimes' Pink And Black Ombre Look That's Super Cool

Grimes' look proves that you definitely don't need to commit to one color when it comes to playing around with a bold hair look - ombre can be super chic, and a great way to try out a new look. She paired pale pink and black for a feminine yet goth-inspired vibe that we're totally digging. And, having the paler pink near her face is genius, as it prevents her from looking too washed out with a darker color. She looks totally gorgeous.

8 Taraji P. Henson's Purple And Silver Ombre Look That Is Totally Cookie-Approved

Taraji P. Henson's character on Empire, Cookie, definitely has a style that's all her own. From leopard print to bodycon, there's nothing Cookie won't rock. However, her hair has always stayed the same shade - which is why we totally love that she's stepped outside the box with this amazing purple and grey ombre look. It's chic, it's a little magical, and it's super flattering on Taraji. Here's hoping she decides to experiment with a few other bold looks - we have a feeling she'd look amazing in just about any shade.

7 Britney Spears' Mermaid Ombre Style

Britney Spears has been in the industry for a long time, which means she's had her fair share of crazy outfits to rock on stage, and over the top hairstyles for photo shoots and videos. We love that she's fearless when it comes to her looks, and this amazing mermaid hair is the perfect example. Fully dyed blue hair might have been a bit over the top, but a gorgeous mermaid ombre? Super cute. We love this look on her.

6 Julianne Hough Says Bye To Blonde And Goes Pastel Pink

You know the saying that blondes have more fun? Well, Julianne Hough, who is normally a blonde, might just have a slight revision to that statement, because she seems to be having an absolute blast rocking her pink locks. With her fair skin and bright blue eyes, any kind of pastel shade would likely look amazing on her, but we totally love the pink. Maybe she'll hop on the grey hair bandwagon next - she'd look super amazing with some icy silver strands.

5 Who Shouldn't Experiment:

5 Avril Lavigne's Multi-Colored Locks That Are A Little Too Juvenile

There's nothing wrong with incorporating a few different shades into your hair look, but it's a lot chicer when those shades are incorporated in a more subtle, blended together fashion. The issue with this look is that she's just got bright strands scattered through her hair - it looks like the kind of thing you'd do at home as a teen, not something you paid to have done in a salon as an adult. We know she loves to channel that punk rock vibe, but this one just kind of missed the mark.

4 Lily Allen's Pale Pink Hair That Leaves Her A Little Washed Out

The problem with picking a shade like pink is that it can be tough to find the exact right shade. Many women don't want to go too super bright, because that's definitely a whole lot of look. However, the risk of going a bit too pale is that you can look washed out - which is what Lily Allen did here. Between the two different tones of pale pink, the black roots, and the overall style, this just isn't the best look for her - we know she could look so much more amazing!

3 Nicki Minaj's Daring Yet A Little Questionable Leopard Dye Look

Nicki Minaj has become known for her super bright clothes, make-up, hair, everything - it's sort of part of her persona. And there are some looks that are kind of whimsical and work, at least on stage. However, there are some that are just a little too over the top, like this look. We're not sure who gave her the idea to dye her hair with colorful leopard spots, but it's just a little bit bizarre. After all, the last thing you want your hair to look like is splotchy.

2 Ellie Goulding's Yellow Hair That Proves It's A Tough Shade For Anyone To Pull Off

Ellie Goulding usually has blonde locks, so when she decided it was time for a bit of a change, she went with something somewhat close to her natural shade - an orange-tinged yellow. The problem is, the shade just isn't quite right. If it was more blonde, it would look great on her. If it was more orange, it would be bold. Heck, even a gorgeous peach shade like Kylie Jenner rocked would be really chic. This shade, however, just misses the mark and does absolutely nothing for her complexion.

1 Kaley Cuoco's Bubblegum Pink Hair - And Eyebrows!

Kaley Cuoco has always seemed like the kind of star who has a really fun-loving personality, so we absolutely adore that she decided to try out pink hair for a while. And the shade itself looks pretty cute on her. The issue is, she decided to go all out and dye her eyebrows pink as well. We know it seems like the thing to do - you'd want your brows to match your hair, right? - but it just looks a little off. There's a reason many people who dye their hair rainbow shades leave their brows natural.
