5 Outdated Warm Weather Hair Looks To Avoid During Summer 2025

Summer 2025 is all about transformation and intentional reinvention. Everything begins to soften, from our wardrobes to our routines. Hair, too, gets a seasonal reset; as the temperatures rise, so do the stakes for our hair. Gone are the styles weighed down by past trends or too many products. In their place comes movement, freshness, and ease.

After years of undone styling, we are witnessing a shift. Hair is trading in last decade's tousled ease for something sleeker and more intentional. Women exclusively spoke with celebrity hair stylist Jessica Ruby, owner of The Flamingo Lounge salons in Los Angeles and New York, for the scoop on which styles are trending, and which 'dos you should ditch. "[Women] are craving the fresh crop — letting go of old energy and stepping into something bolder," says Ruby. "Expect to see Prada Bobs, structured mid-length cuts, and confident blunt shapes."

Color is getting the same treatment. Ruby notes a magnetism towards rich reds, from deep garnets to sunlit coppers. There's also a more toned-down approach to blonde, with Ruby's salon seeing a surge in "recession blondes — soft, lived-in blonding that grows out gracefully."

It's all about smart beauty: personalized, powerful choices that feel fresh and future-forward. That also means knowing what to leave behind. Sleek styles and breezy cuts may be in, but these five throwback trends are better left in summers past.

Is the deep side part the skinny jeans of hair? The answer is quite possibly, (because let's face it, we need to prepare for skinny jeans not coming back any time soon). The line has shifted — quite literally — with modern trends leaving behind the form-fitting pants once favored by punks, power dressers, and early-2010s YouTubers.

In its place comes something styled much more intuitively. As Jessica Ruby exclusively tells Women, "I'm predicting a major style evolution this summer: Deep side parts are being left behind in favor of center parts, curtain bangs, and soft face-framing layers that create a more effortless, up-to-date look." Fortunately, there's no shortage of hair inspo from celebs who have rocked chic curtain bangs. Sabrina Carpenter gave them a caffeinated dose of old Hollywood glamour, Alexa Chung brought her signature indie insouciance to the look, whilst Kelly Rowland proved how the style can strike the balance between elegance and edge.

The era of "I just threw it up" hair might finally be drawing to a close. Maybe it's for the best; messy buns were never quite as effortless as they claimed to be. More often, they relied on a lucky cocktail of product, pins, strategic tugging, and some good, old-fashioned wishful thinking.

This summer, the messy bun gets a glow-up. According to Ruby, "Messy top buns are feeling outdated. Sleeker, structured updos — whether slicked back or softly tousled with intention — are replacing the thrown-together styles." But that doesn't mean uniformity. The new updo meets you where you are, and here's one for every texture, every mood, and every kind of summer day. The best updos from curly-haired celebs celebrate definition and volume, rather than smoothing them away. Elsewhere, the modern celeb updos that scream the '90s welcome nostalgic flair with a fresh, editorial edge.

If you've got a thick head of hair and no patience for bobby pins slipping out by midday, updo hairstyles that are great for thick hair offer sculptural structure without struggle. And for those who want ease without sacrificing on-trend style, claw clip looks prove that minimal effort can return maximum impact.

Of all the trends we're trimming back this summer, streaks are high on the list. At least, they are in their original form. The overly distinct stripes that filtered through the internet's e-girl aesthetic — high-contrast and front-loaded — are fading fast. This isn't the MySpace revival.

That being said, there's no need to rule out funky, dramatic hair entirely. "Harsh e-girl streaks are evolving into softer placement highlights — especially woven into shags and wolf cuts, which are still staying strong through summer 2025," explains celebrity stylist Jessica Ruby. The aim is to let the color amplify a cut, rather than dominate it.

Where once we saw thick, disconnected stripes that overwhelmed the shape of the hair, we're now witnessing a return to tonal pieces placed with precision. That way, they can catch the light and add a romantic depth.

When Kim Kardashian debuted her icy blonde bob, it sent fans (and hair stylists) into overdrive. Cool-toned blonde became the aspirational shade almost overnight, until people realized how much commitment it takes to maintain. In summer 2025, the ice is melting, and people are warming to something more sun-kissed and sustainable.

Naturally, our favorite stars are setting the tone (brass-free, of course), with an abundance of blonde shades to inspire your next salon trip. As Jessica Ruby notes, "Warmer tones, golden highlights, and buttery blondes are making a comeback, offering a softer glow that's easier to maintain."

Hair accessories are anchoring our looks again this season, framing personal style over simply embellishing it. The era of minimal pins and barely-there barrettes is giving way to the loud and deliberate. According to stylist Jessica Ruby, "Accessory trends are shifting too: statement pieces like oversized bows, bold clips, and dramatic headbands are replacing tiny rhinestone pins, making accessories a true focal point again."

Of course, hair accessories, like most adornments, toe a delicate line. A misfire can feel like a holdover from adolescence, falling perilously close to mall-era sentimentality at the expense of refinement. But in the right hands and with the right materials, they can make even the simplest outfit feel fully styled.
