Think Pink With 20 Cotton Candy-Colored Dye Jobs

1. Deep Side Parts

Coming in at #1 on our "outdated" list are deep side parts. They used to something we admired on everyone from Amy Winehouse to Katy Perry, but now they remind us of the questionable choices we made in our early 20s.

2. Space Buns

Princess Leia may look great wearing her space buns in the Star Wars franchise, but we think you shouldn't bring them into 2025. The last time someone on our team wore them was between 2018 or 2019, so that should say a lot.

We don't say this often, but let's wear hairstyles that don't revert us back to our grade school days.

3. Side Braid

Unless you're trying to relive your childhood days or want to mimic Blake Lively's character in It Ends With Us, this outdated hairstyle shouldn't be on your list of favorite looks to wear. There's other braided styles you can wear that are way more stylish anyway!

4. Super Visible Highlights

Whether you're getting microlinks or a sew-in, wearing super visible highlights in 2025 is truly outdated. It's one thing to switch up your style, but it's another to let the world know how much you love a good contrast by letting your hair scream it from the mountaintops.

Keep your color of choice seamless this year if you decide to get a color service.

5. '60s Up-Do

There's a time and place for everything, including updos that resemble what was popular during the '60s. If you must wear this style, go for a more modern take that doesn't feel as stiff. You might want to update your bangs too.

6. Wand Curls

When's the last time you heard someone mention this once popular style? Chances are you haven't because it's a reminder of how long it took to achieve overly done curls. Depending on the size you wanted, you could spend anywhere from 45 minutes to over an hour on this style. Oh, and it was mandatory to wear the accompanying glove that came with the 'wand' or else you risked burning your fingers!

No thank you!

7. Barbie Bleach

Remember when it was a cardinal sin to show up to the beach without "effortlessly wavy" hair? It seems more people are moving away from that and embracing 'messy' buns and the beauty of textured hair. It's one thing if you hair naturally looks like this, but it's another if you try to make your hair conform to this style just because it's "on trend."

Newsflash: you don't have to force your hair to do something it doesn't want to! (And not everyone has to look like Serena van der Woodsen!)

8. Millennial Pouf

Oof, how can we forget the millennial pouf? This was one of our go-to hairstyles that we swore we'd always wear. Little did we know how much we'd avoid it once we graduated from college.

It's not the most annoying style, but we're throwing this one in the "outdated" bag so we can't even pretend we're going to start wearing it again.

A Chic Gray Bob 

Go for the classic style by asking for this exact cut at the salon. This shape makes everyone looks amazing and is probably one of the most versatile gray bobs that can inspire your next trip to the salon. To maintain it, you'll want to protect your hair with a scarf at night. During the day, make sure you use a heat protectant before curling it with one of your flat irons.

This blunt hairstyle looks SO good with glasses, too! Pair it with a statement lipstick, and you're really making some stylish moves!

A Gray Lob

Bobs can be as short or long as you want as evidenced by this longer 'lob.' This is for the person who doesn't want to have hair like Rapunzel, but still wants to maintain some of their length. If you ever want to go for a shorter look with this style, all you have to do is pin curl the ends of your hair.

I love how this cut cascades with naturally curly or wavy hair!

I mean, look how flattering this is!

Plus, this slightly shorter length can really add some body to the ends!

A Bob With Bangs

Listen, a bob and bangs are a match made in heaven. I don't make the rules — it just works beautifully! If you're looking to really frame your face, this is a really great option! And look at how it makes your gorgeous features stand out even more!

A Perfectly Curled Under Gray Bob 

Then again, you can keep it short and simple with this perfectly curled gray bob. Whether you consider yourself bold or not for rocking this style, it's one of those looks that'll stand out if you add a beautiful balayage to it.

Did we just give you an idea? We think so!

And with the round glasses to boot? Yeah, this woman screams, "I look good, and I cannot be stopped!"

This look can also add a lot of softness to your aura, too. Really love how it hugs her face here!

A Shorter Gray Bob With Side Bangs

The best thing about shorter hairstyles are their ability to highlight someone's features. If you have an oval face with high cheekbones, this style will amplify them. Not only that, but you'll have fun parting your hair to create side bangs.

Tip: Use a small flat iron to create depth without over-curling your hair.

Look at how this cut angles perfectly with her face! So sleek!

A Stacked Or Graduated Bob 

Another chic bob to wear is a stacked or graduated bob. Similar to the stylish woman in the picture, we imagine this hairstyle is for the woman who loves letting her personality shine through whatever she's wearing. We're jumping the gun, but this is one of those hairstyles you'll have fun planning outfits around.

I just love how this frames and elongates her face! The hairstyle makes her look refreshed and young, giving features like her eyes a chance to really shine!

A Gray Wavy Bob

This is the perfect length and shape to make your natural curls or waves shine. You won't even have to worry about curling your hair with this style because it doesn't require you to. If you're not sure what to use on your hair, we recommend using products from Sienna Naturals to help with the overall health of it.

This hairstyle adds so much movement to your look!

You don't have to have such exaggerated waves, either. Some subtle waviness to your gray bob hairstyle is just enough to add that beautiful movement!

A Fully Curly Bob

Curly hair don't care? A gray bob hairstyle is PERFECT for you. This look says you're fun, fabulous, and ready to have a good time. Plus, it's yet another look that goes oh-so well with your statement glasses — the perfect chic look, if I do say so myself!

1. Flower Crowns

Rainbow Flower Crown

When millennials wanted to look 'boho chic,' they immediately busted out the flower crowns. This accessory infiltrated practically every occasion, from high school dances and music festivals like Coachella – or even (sigh) regular trips to the mall.

While the trend might've felt fun and carefree at the time, flower crowns are super cliché today and just remind me of Tumblr's heyday (IYKYK).

2. "Geek" Glasses

Black Nerd Glasses

It's funny to think about how popular wearing fake "geek" glasses was, particularly since so many teen movies of the time, like Mean Girls, sensationalized being "cool" and "popular."

Nonetheless, plenty of millennials set out to appear quirky by topping off their outfits with thick, oversized hipster frames, even if they didn't actually need glasses. Some people even used their leftover 3D glasses from movie theaters and simply popped the lenses out – guilty!

3. Hair Feathers

Feather Hair Extension Clip

Similar to flower crowns, hair feathers emerged as a bohemian-inspired way to add a pop of color and texture to your locks. Some people opted for thinner solid or multicolored strands; meanwhile, others went full-throttle with larger feather shapes or even bead attachments.

This is another "hipster" trend that, while maybe still appropriate for some music festivals, should stay in the past when it comes to everyday wear.

4. Jeggings

Halara Flex High Waisted Stretchy Leggings

Jeggings were supposed to be the perfect blend of comfort and style... or so we thought. The idea seemed genius at the time, but in retrospect, they were just a fashion mistake.

This pant style attempted to blend two completely different types of garments and created a result that's now considered a fashion faux pas. Jeggings are just too tight to ever be flattering and don't deliver that same classic denim look.

5. Converse Sneakers With Anything

Converse Chuck Taylor All Star Canvas Sneakers

Skinny jeans, skirts, maxi dresses, and mini dresses. Today, you'd probably pick different shoe choices for all of these outfits, but millennials undoubtedly had a go-to: Converse.

These sneakers were the perfect footwear for practically any look, but the trend quickly became overused. Even celebrities were showing up in low-cut Converse to walk the red carpet, a statement that would leave younger generations scratching their heads today.

6. Belts Over Shirts

Grommet Leather Belt

Along with the excessive layering of tank tops and t-shirts came the addition of belts on top. While this might've been an attempt to add some structure or flair, many belts in the 2000s were more clunky than chic.

This trend is making a comeback, particularly with oversized outerwear. But, again, younger generations today are making more pattern- and color-conscious decisions (and not just cinching their waists while wearing Hollister v-necks, LOL).

7. Ombré Hair

Ombré hair is often associated with balayage, a hair-painting technique that remains insanely popular in 2025. However, many millennials didn't hit the salon to achieve their ombré – and took matters into their own hands at home.

Regardless of whether they tried to darken or lighten, it typically resulted in a not-very-well-blended horizontal line of color across their hair.

8. Fedoras

Finally, I believe that you should be entitled to compensation if you've been personally victimized by a fedora. Everyone from Justin Timberlake to Paris Hilton wore these hats, making millennials think they were cool. In hindsight, perhaps everyone (including the A-listers) blundered with this fad.
